LifePO4 BMS 4s are rechargeable batteries that can connect to solar panels to store excess solar energy. These batteries are used for power backup, solar storage, and electric vehicles. These are about half the weight of AGM or lead acid batteries which have high charge cycles. They are also more stable than other Lithium Iron (Li-ion) batteries. We also have 24V, 36V & 48V Batteries, and BMS packages available. To know more information, visit our website now!
