The LiTime 12V 100Ah Plus is a Group 31 LiFePO4 deep-cycle battery built for trolling motors and electric outboards. It delivers high sustained current (150A for 3 minutes, 300A for 10 seconds, 500A for 1 second), which is more than most 100Ah lithium batteries of this size offer. A 100A smart BMS with low-temperature cutoff and IP65 sealing suits marine use, and Bluetooth lets you watch charge and current from your phone. Owners say it holds steady power all day and lasts several fishing trips between charges; the main gripe is that its Group 31 footprint does not fit trays sized for Group 27 lead-acid batteries.

Rated 4.9 out of 5 from 159 ratings, buyers mostly praise the steady power, long runtime and working Bluetooth monitoring. The recurring complaint is the Group 31 footprint forcing a battery tray change.
This 12V 100Ah LiFePO4 deep cycle battery is made for trolling motors and electric outboards. It sustains 150A for 3 minutes and handles 300A for 10 seconds or 500A for 1 second. It works with Minn Kota, MotorGuide, Garmin, Lowrance, Newport, Haswing and other brands in 12V, 24V and 36V systems. It is not for engine starting.
The battery uses EV-grade LiFePO4 cells and an ABS housing. It is rated for 6,000+ cycles at 80% DOD. The IP65 rating protects it against water and dust in marine and humid environments. A 100A smart BMS provides 20+ protections, including low-temperature cut-off, overload auto-recovery and added moisture and salt-spray resistance.
Bluetooth 5.0 monitoring shows battery status, performance and key data on your phone. The Group 31 size is a drop-in replacement for lead-acid batteries. Check that your battery compartment has enough space first, since some buyers had to change battery trays from Group 27 to Group 31. Up to 4P4S can be connected, for systems of up to 51.2V 400Ah (20.48kWh).
