LiFePO4 off grid batteries

Australia isn’t a tiny country; instead, it spans thousands of square kilometres, with most of the population across the eastern coastline side. Many families reside in mainland Australia where life is very harsh as the various utility companies find it hard to facilitate them. Electricity is a basic necessity; we can’t imagine living without it without that. The solution here is the off-grid energy solutions, while solar off-grid solutions are on top as Australia is blessed with sunlight more than eight hours a day.

The solar system will produce electricity continuously during the daytime. At the same time, the LiFePO4 off grid batteries are a great energy source when sunlight isn’t an option due to bad weather or evening time. Deep Cycle Systems is an energy company serving Australian families by providing affordable energy solutions that best suit their needs. We are a team of committed experts who are industry leaders.

Lithium-ion Vs Lead-Acid Batteries

Lithium-ion batteries or LiFePo4 batteries have matured enough to replace the lead-acid batteries completely. They are far better than them, with many advanced features that add value. A lead-acid battery is the first one that humans have used for over 150 years; however, they seem to be out of touch with modern functions. On the other side, a lithium phosphate battery is about three-decades-old technology; however, it provides numerous benefits that a lead-acid battery can’t compete with.

An off-grid lead-acid battery needs regular maintenance and check-up to avoid battery damage, while it also requires ventilation to prevent any explosion due to hydrogen gassing. This is not the case with a lithium battery, as it is designed and proved to bear harsh weather conditions. It can operate between five degrees Celsius and sixty-five degrees Celsius. Apart from its role for domestic use, a LiFePo4 battery is getting the attention of electric vehicle manufacturers aerospace and marine projects.

A significant advantage of a lithium battery over a lead-acid battery is its extended backup time due to its ability to store more charge, and surprising element is its compactness with many features to outperform lead-acid technology, including:

High Energy Density

Off-grid LiFePo4 batteries are known for their ability to store more energy than any other technology, and this makes them lightweight, and you can quickly move them when required. These batteries are three times lighter than a typical lead-acid battery backup.

No Memory Effect

Memory effect in a battery can lead to energy losses as it impacts the ability to hold current. It is also known as the battery effect or lazy battery. This could cause a repeated recharge cycle after a battery is used partially and thus not discharged to its full potential. That is not the case in a lithium-ion battery. You can charge and discharge a lithium battery as per your requirements.

Low Self-Discharge

A self-discharge is a condition in which a battery loses its stored energy without connecting to an active source. This phenomenon is caused by the chemical reaction of a battery and impacts the lifespan of a battery. Typically, general batteries have a ten to twenty per cent ratio of self-discharge. In contrast, the lithium-ion battery bank has a shallow discharge rate of under three per cent during a month.

Deep Discharge

A lithium battery provides more than 90% discharge ability to make the best use of your investment. A lead-acid battery will provide only fifty per cent of the stored energy, which means you can benefit from only half of the investment in your battery, and the rest is considered a useless expense. LiFePO4 off grid batteries can be charged in a brief time.

FAQ

Lithium Ferrophosphate (LFP) is a flame retardant, stable, safe and proven cell chemistry that has a very good energy density around 325 Wh/L. This cell chemistry can be engineered for various applications by adjusting the ratio of elements to provide high performance characteristics. E.g. the DCS marine battery range runs 2C cells, which means our little 75Ah battery will discharge comfortably at 75Ah x 2C = 150A. The DCS 80Ah Extreme runs 10C cells which means the 80A can comfortably discharge at 80Ah x 10C = 800A but is of course limited to lower currents due the the Battery Management System.

LFP also has very good cycling durability between 2,000 ~ 12,000 cycles can be achieved depending on how well the cells are managed, and the lowest rate of capacity loss (aka greater calendar-life) compared to other lithium cell chemistries.

Battery cells are simply a bunch of resistors with the ability to store energy. A 100Ah battery pack has a different resistance characteristic compared to a 50Ah battery pack, that theoretical difference in resistance is 2:1. So if you connect a 100Ah battery in parallel to a 50Ah battery there is no way for these two batteries to equalise and therefore you can’t charge them correctly. So for example connecting a 60Ah calcium starting battery to a 120Ah AGM via a VSR (Voltage Sensing Relay) you cannot charge both batteries correctly and from that day onwards you are prematurely destroying both battery packs. Same theory applies with lithium’s it’s still a battery pack.

What’s the solution? A DC-DC charger, you now have a permanent point of isolation (meaning that both batteries are never connected to each other in parallel). The DC-DC charger takes the surplus power from battery A (engine) and chargers battery B (aux/house). This device now allows any battery capacity and or chemistry to be used.

Yes you can, but lithium’s have a different voltage curve, so you would still need to use a programmable VSR to dial them in correctly. You would also need to ensure the batteries are programmed to never exceed a 10%SOC variance, any larger and you risk damaging the BMS's. These devices also draw a lot of power when engaged to so it’s best to run the two batteries in permanent parallel and run a load disconnect instead of a VSR.

Lithium battery cells have a super low resistance so are very easy to charge and very efficient. This level of efficiency means you can charge them at very high C rates. For example if you look at the charge rate of a 100Ah AGM battery the recommended charging current will be around 25A, which is a 0.25C charge rate. If you consider the DCS 12V 100Ah Lithium battery it can be charged at up to 70A which is a 0.70C charge rate. This means you no longer need to consider DC-DC chargers as you can connect our batteries directly to high power charging devices such as suitable alternators, or large buck boosters. For example our popular dual 90Ah battery system for boats and 4WD vehicles, can be connected to alternators up to 160A.

Because our batteries are internally voltage regulated and because our BMS has such a high sustainable peak discharge current they will do an amazing job of equalising very quickly.

The BMS will emergency open circuit the battery terminals to protect the cells. This means there is no longer any resistance in the system. The BMS needs a 12V supply with at least 1A of current to release and wakeup from a cell emergency protection state.

Most mains chargers with a lithium profile will do a slow recovery charge as will most solar regulators. Some chargers on the market today that are advertised as ‘lithium’ compatible still don’t have the firmware to do a slow recovery charge to release BMS’s. If you have a charger that will not wakeup the BMS, easiest way to wake it up is to connect a unregulated solar panel directly to the battery terminals, ensure all loads are disconnected before you do this. Having said that every system should have a suitable low cut off voltage to shutdown loads/accessories so that the batteries are not fully drained.

"Batteries cannot be left flat/empty, if the low voltage cutoff is triggered the battery pack should be fully charged as soon as possible. If access to a suitable charger is not possible, disconnect all loads from the battery terminals. The warranty will be void if the battery pack has been left in a low voltage cutoff state for longer than 14 days."

Most important thing is to isolate everything from the battery terminals, as cables/loads connected to the terminals causes more power drain as the FET gates have to remain closed to cull the accessory standby loads connected to the battery pack + offset BMS standby power consumption.

Use the following settings:

Charged voltage 14.0V
Tail current 4%
Charged detection time 1min
Peukert 1.05
Charge efficiency 98%
Current threshold 0.1A
C rates: refer to the battery pack capacity

Fully charge to 100% isolate everything from the terminals and leave for max 3 months and then cycle (fully discharge and fully charge) and leave again for 3 months etc…. Minimum 4 cycles per year to not effect the cells capacity.

The reason many factory batteries fall over after 9/12 months is because modern/smart alternators typically drop the alternators voltage output to 13.5/13.6V. This voltage is not high enough to charge wet/calcium/lead acid batteries so from the getgo they are destined to fail prematurely. They are typically under charged to around ~80%SOC at these voltages.

So what happens when DCS Hybrid batteries are connected to smart alternators? Exactly the same thing they get charged to around the same 80%SOC. However because LFP has no memory effect that's perfectly fine. By only charging to 80% you are further improving the service life of our batteries. It's no not necessary to charge our batteries over 80%SOC. The only advantage is that you give the BMS a chance to detect full charge voltage and calibrate the SOC readout. So try to plug into mains once a week to fully charge your batteries, especially if your not running any fixed solar supply.

All DCS 12V cylindrical cell packs can be charged as follows:

Bulk: 14.4V
Float: 13.5V

The DCS 12V 180Ah Auxiliary prismatic cell packs (SKU: DCS-12V-180Ah) need to be charged as follows:

Bulk: 14.2V
Float: 13.5V

When the battery pack is discharged down to 11.50V the BMS resets to 0%SOC and now is placed in a relearning state - the pack must be fully charged continuously without stopping to calibrate again. Charge it on a mains charger to 14.60V.

Depending on the usage pattern, best to fully cycle the batteries once every 3 months to give the cells a refresh. To fully cycle a 12V pack discharge to 11.50V and charge to 14.60V.

CELL SAFETY INFO - Why LiFePO4 (LFP)?

Lithium Ferrophosphate (LFP) is a flame retardant, stable, safe and proven cell chemistry that has a very good energy density around 325 Wh/L. This cell chemistry can be engineered for various applications by adjusting the ratio of elements to provide high performance characteristics. E.g. the DCS marine battery range runs 2C cells, which means our little 75Ah battery will discharge comfortably at 75Ah x 2C = 150A. The DCS 80Ah Extreme runs 10C cells which means the 80A can comfortably discharge at 80Ah x 10C = 800A but is of course limited to lower currents due the the Battery Management System.

LFP also has very good cycling durability between 2,000 ~ 12,000 cycles can be achieved depending on how well the cells are managed, and the lowest rate of capacity loss (aka greater calendar-life) compared to other lithium cell chemistries.

WHY YOU CANNOT USE A VSR BETWEEN TWO DIFFERENT BATTERIES CAPACITIES & CHEMISTRIES?

Battery cells are simply a bunch of resistors with the ability to store energy. A 100Ah battery pack has a different resistance characteristic compared to a 50Ah battery pack, that theoretical difference in resistance is 2:1. So if you connect a 100Ah battery in parallel to a 50Ah battery there is no way for these two batteries to equalise and therefore you can’t charge them correctly. So for example connecting a 60Ah calcium starting battery to a 120Ah AGM via a VSR (Voltage Sensing Relay) you cannot charge both batteries correctly and from that day onwards you are prematurely destroying both battery packs. Same theory applies with lithium’s it’s still a battery pack.

What’s the solution? A DC-DC charger, you now have a permanent point of isolation (meaning that both batteries are never connected to each other in parallel). The DC-DC charger takes the surplus power from battery A (engine) and chargers battery B (aux/house). This device now allows any battery capacity and or chemistry to be used.

What if both batteries are the same, can I run a VSR between exactly the same two batteries?

Yes you can, but lithium’s have a different voltage curve, so you would still need to use a programmable VSR to dial them in correctly. However these devices draw a lot of power when engaged to so it’s best to run the two batteries in parallel and run a load disconnect instead of a VSR.

The advantages of the lithium battery cell chemistry

Lithium battery cells have a super low resistance so are very easy to charge and very efficient. This level of efficiency means you can charge them at very high C rates. For example if you look at the charge rate of a 100Ah AGM battery the recommended charging current will be around 25A, which is a 0.25C charge rate. If you consider the DCS 12V 100Ah Lithium battery it can be charged at up to 70A which is a 0.70C charge rate. This means you no longer need to consider DC-DC chargers as you can connect our batteries directly to high power charging devices such as suitable alternators, or large buck boosters. For example our popular dual 90Ah battery system for boats and 4WD vehicles, can be connected to alternators up to 160A.

WHY CAN DCS BATTERIES BE CONNECTED IN PARALLEL WITHOUT ANY EXTERNAL COMMUNICATION SYSTEM?

Because our batteries are internally voltage regulated and because our BMS has such a high sustainable peak discharge current they will do an amazing job of equalising very quickly.

WHAT HAPPENS IF I FULLY DISCHARGE MY BATTERY TO EMPTY?

The BMS will open circuit the battery terminals to protect the cells. This means there is no longer any resistance in the system. The BMS needs a 12V signal with at least 1A of current to release and wakeup from a cell protection state. Most mains chargers with a lithium profile will do a slow recovery charge as will most solar regulators. Some chargers in the market today that are advertised as ‘lithium’ compatible still don’t have the firmware to do a slow recovery charge to release BMS’s. If you have a charger that will not wakeup the BMS, easiest way to wake it up is to connect a unregulated solar panel directly to the battery terminals, ensure all loads are disconnected before you do this. Having said that every system should have a suitable low cut off voltage to shutdown loads/accessories so that the batteries are not fully drained.

BATTERY MONITOR SETTINGS

Use the following settings:

Charged voltage 14.0V
Tail current 4%
Charged detection time 1min
Peukert 1.05
Charge efficiency 98%
Current threshold 0.1A
C rates: refer to the battery pack capacity

What is the best state/charge to store these batteries ?

Fully charge to 100% isolate everything from the terminals and leave for max 3 months and then cycle (fully discharge and fully charge) and leave again for 3 months etc…. Minimum 4 cycles per year to not effect the cells capacity.
