What type of cells do you use in the LiFePO4 battery?
We use lithium iron phosphate or LiFePO4.

What are the advantages of the LiFePO4 battery?
LiFePO4 batteries have an advantage in overall life, lasting anywhere from 3000 to over 4000 cycles, depending on external conditions. This higher number of charge/discharge cycles, as compared to other lithium chemistries make this battery great for permanent off-grid systems that require longer life cycles for daily energy use.

What is the downside of the LiFePO4 battery?
Because of their lower energy density, LiFePO4 batteries are heavier than other lithium chemistries. This can also affect their charging performance at very low temperatures.

What is the cycle life of the LiFePO4 battery?
About 3,500 cycles at 80% remaining capacity, and 6,500 cycles at 50% remaining capacity, the industry standard.

Does this battery require any maintenance?
As with all lithium battery types, no maintenance is required of the LiFePO4 battery. Each battery has a built-in battery management system (BMS) that will monitor cell voltages, currents, and temperatures to ensure safety and long life.

Can I mix battery chemistries with the Titan Power Station?
Yes, you can mix battery chemistries with your Titan Power Station; however, it needs to be reprogrammed to be used with the new smart A/C charger.

How can I fully charge my battery to calibrate my meter?
In order to fully charge your battery to force the meter to recalibrate, you must discharge the battery below 26.0V and then charge it up to 28.8V via solar or the included AC charger. The meter will then calibrate.

The LiFePo4 battery has a power button on it, when do I turn it on or off?
The power button on the battery should be off before connecting the battery to other batteries or the power module but it should be on any time you are using power. The LED light will not go off when connected to batteries that don’t have a power switch (older NMC batteries). This is fine and uses very little power. However, the battery should be removed for long storage so there is no battery drain.

The LED light on the LiFePO4 battery does not go off even when it is turned off?
The LED light on the battery will stay on whenever power is available. If the battery is connected to a battery that is not turned off, or does not have a battery power button, the LED light will stay on. This is fine, and uses very little power; however, the battery should be removed for long storage so there is no battery drain.

Is Lithium Iron Phosphate better than other battery chemistries?
Lithium iron phosphate batteries offer numerous benefits: faster charge and discharge rates, wide temperature range operation, longer lifespan, zero maintenance, and a 5-year warranty. They provide reliable and efficient power storage solutions.

How does Point Zero Energy's LiFePo4 Battery compare to others on the market?
Point Zero Energy takes pride in offering the industry's highest energy density LiFePO4 battery. With an impressive 52 wh per pound, our LiFePO4 battery provides more power for less weight compared to other LiFePO4 options in the market. This translates to optimal efficiency and performance for all your energy needs.

How much does the LiFePO4 battery module weigh?
Approximately 45 lbs.
