Only applicable for devices under 230.4Wh. Please check the rated power of the equipment before placing an order! !
Light clean energy: only 25% of the weight of equivalent lead-acid batteries, but with a lifespan of at least 6 times. The properties of "environmentally friendly and clean energy" make them an ideal alternative to the most traditional lead-acid deep cycle batteries.
LONG LIFE - High quality lithium phosphate batteries (LiFePO4) have a long cycle time. Under 100% DOD conditions, the battery capacity can be longer after charging and discharging 1C and reach 3500 cycles. The longer service life (up to 5000-7000 cycles) will be even lower, and the unloader will reach.
BUILT-IN BMS & LOW TEMPERATURE CHARGING PROTECTION Our powerful built in BMS can automatically stop charging below 0℃ to protect the battery from damage. By the way, it avoids the most common problems of LiFePO4 batteries, such as temperature changes, overload, overload, overcurrent, overload, overheating and grounding, which can cause battery failures.
