Discover® AES PROFESSIONAL LiFePO4 battery models are purpose built to replace and fit the standard groupings of batteries. AES PROFESSIONAL batteries incorporate a proprietary high-current BMS that delivers superior peak power along with lightning fast 1C continuous charge and discharge rates, plus they feature COLD CHARGE functionality allowing for cold temperature charging to begin from -20°C / -4°F. Independently tested to the highest safety, performance and transportation standards, a single battery will do the work of many lead-acid batteries and unlike lead-acid batteries can be continuously operated in a Partial State of Charge (PSOC) without degrading performance.
