Discover HELIOS Battery

DISCOVER HELIOS Energy Storage System batteries are purpose-built for the drop-in replacement of 24V and 48V groupings of the popular GC size battery used in off-grid solar systems. DISCOVER HELIOS batteries incorporate a proprietary high-current BMS that delivers superior peak power along with lightning-fast 1C continuous charge and discharge rates, and unlike lead-acid batteries can be continuously operated in a partial state of charge (PSOC) without degrading performance. DISCOVER HELIOS features COLD CHARGE functionality allowing cold temperature charging to begin from -20⁰C / -4⁰F.
