BlueNova BN52V-280-14.5K SBB LiFePO4 Single Box Battery

Product Description:

SBB™ batteries have been developed to allow for the easy installation of 14.5kWh of high performance battery capacity in single-module installations as well as for expanded capacities in increments of 14.5kWh. Up to 9 x SBB™ modules can be connected in parallel for a total installed capacity of >130kWh.

The integrated BMS in SBB™ batteries is a completely redesigned version of the BMS integrated in our High Current & Battery Rack Series (discontinued but still supported since April 2024). Several new improvements have been made to the new BMS in SBB™ modules, while parallel integration functionality with the legacy BMS it is based on remains intact. This means that SBB™ batteries are 100% parallel-compatible with existing HC & BR installations.
