This is a 12V 100Ah LiFePO4 deep cycle battery for trolling motors. It delivers 1280Wh of energy and is built for 30–70 lb trolling motors. It is sized as a drop-in replacement for Group 31 lead-acid batteries.
The battery uses EV-grade LiFePO4 cells rated for 4,000+ cycles at 100% DOD. It has an IP65 rating for resistance to moisture, dust, salt spray and vibration. A smart BMS with 20+ protections guards against overcharge, over-discharge, overcurrent, short circuit and temperature extremes. If overload protection triggers, the battery recovers automatically with no manual reset.
Charging stops automatically below 32°F (0°C) and resumes above 41°F (5°C). The recommended charge is 14.4 ± 0.2V CC/CV at 20A, using a LiFePO4-compatible charger. If deep discharge triggers BMS protection, disconnect the battery and let it rest for 30 minutes. If needed, use a charger with a LiFePO4 activation function to reactivate it. This model has no Bluetooth monitoring, so its state of charge can only be roughly estimated from resting voltage.
