Charging Your LiFePO4 Batteries

The most important thing when it comes to charging your LiFePO4 battery is that you use the correct charger. Look for a charger that is specifically designed for li-ion or lithium iron phosphate batteries, as these are specifically designed for this type of battery and offer better charging accuracy and protection from overcharging.

Once you have the correct charger, make sure to select the correct voltage settings based on the specifications of your battery. This will ensure that your battery gets safely charged without any risk of overcharging or overheating. Finally, when charging always make sure to follow the manufacturer¡¯s instructions closely and don¡¯t leave it unattended while charging.

Things to Avoid When Charging Your LiFePo4 Battery

When it comes to charging your LiFePO4 battery there are certain things that you should always avoid doing in order to keep it safe and properly functioning:

Never use non-lithium or lead acid chargers ¨C these are not intended for Lithium-Ion or Lithium Iron Phosphate batteries;

Do not use car chargers ¨C they cannot accurately measure how much charge is left in a cell which can run down its lifespan;       

*Never attempt to jump start a dead cell ¨C this will cause additional damage;      

*Avoid discharging past 80% capacity - going beyond this point could harm the cells leading them towards early retirement.


LiFePo4 batteries are becoming increasingly popular across industries due to their long life cycles, superior performance in extreme conditions, and maintenance free convenience. That said, if you want yours to function safely and reliably then following the above guidelines on how best to charge it is essential in preserving its maximum life expectancy.
