This Mini battery fits 100Ah into a Group 22NF case that WattCycle lists as 39% smaller by volume and 11% lighter than its standard 100Ah battery. Bluetooth connects to the WattCycle app for live monitoring, and a 100A BMS disconnects the battery automatically if there is a fault. It works down to -4 F.
