Features of 12V 40Ah lifepo4 starting battery

1. Easy to use, no need to add water

2. Small size, light weight, and easy to carry.

3.Fuel saving by 5%,. The voltage of lifepo4 batteries is very stable (13.2V), so the car ignition system can always maintain a higher and more stable voltage.

4. Long service life.which are not easy to age. After 2000 times of repeated charging and discharging, the decay rate of its capacitance is only 15%.

5.Good start at low temperature,lithium iron batteries can maintain 80-95% of energy at minus 20 degrees.

 

BMS function of 12v 40ah lithium ion starting battery.

Lithium iron phosphate battery bms can effectively monitor, protect, energy balance and fault alarm of lithium battery pack, thereby improving the working efficiency and service life of the entire power battery pack.
