These batteries may look fairly similar to lead acid batteries, but they’re actually made up of regular pouch LiFePO4 cells, which are in mass production for many portable devices. An internal battery management system (BMS) ensures all cells are uniformly charged and discharged, as well as providing short circuit, over current, and reverse polarity protection. This provides you with a higher degree of protection than a traditional lead acid battery which is unprotected, and can discharge rapidly under short circuit conditions, causing fire and damage. The internal BMS will also limit discharge and manage cut-off voltage, to further protect the internal cells.
It’s not suitable for a primary vehicle starting battery, however is absolutely perfect for house batteries, backup batteries, and virtually any other application where you would typically use a large lead acid / AGM battery.
These batteries can be used at max of in 4 series or 4 in parallel setups. In combination, this is limited to a max of 4 in series and 2 in parallel at the same time.
It's recommended to regularly charge the batteries independantly to maintain internal cell balance.
