The next generation of power storage is here! These LiFePO4 batteries may look fairly similar to lead acid batteries, but internally they’re a totally different, next generation concept. They’re actually made up of regular 32650 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.
