Lightweight 12V 100Ah LiFePO4 power for electric boat motors, fishing boats, and long days on the water – with more charge cycles and less maintenance than lead-acid batteries.

PROTECTION AGAINST HIGH CURRENTS

150A Smart BMS. For electric boat motors.

The intelligent 150A BMS gives your 12V electric boat motor more power reserve and monitors the battery status in real time. It protects against overcharging, deep discharge, overcurrent, short circuit, and extreme temperatures – for a safe, stable power supply and long days on the water.

Ready for cold days

The intelligent BMS stops charging at 0 °C and resumes it at 5 °C to protect the cells. Discharge protection kicks in at −20 °C – for cold mornings, storage on board, and use on the water.

Frequently Asked Questions

Any questions?
You can find more information in our Frequently Asked Questions.

Question: What applications is this 12V 100Ah TM battery particularly suitable for?

Answer: It was developed for 12V electric boat motors, fishing boats, bass boats, kayaks, inflatable boats, and small onboard power systems. It is also suitable for motorhomes, solar systems, and emergency power supply when a compact, powerful 12V LiFePO4 battery is needed.

Question: Is this battery suitable for electric boat motors?

Answer: Yes. With its intelligent 150A BMS and multi-stage peak current output, it is designed for 12V electric boat motors. It supports short start-up surges and steady motor loads. Always check your motor's voltage and current requirements before use.

Question: What does the 150A BMS mean in practice?

Answer: The smart 150A BMS enables a higher continuous current output than many basic 100Ah batteries. It powers electric boat motors, onboard electronics, pumps, and other 12V devices and protects against overcharging, deep discharge, overcurrent, short circuits, and extreme temperatures.

Question: How does 550A peak current help when operating electric boat motors?

Answer: When starting up or during sudden load changes, electric boat motors and onboard devices may briefly require high currents. This battery delivers up to 550A for 1 second, providing additional power reserve for short peak loads.

Question: Is this battery waterproof?

Answer: The battery has IP67 protection and is suitable for damp conditions on board and outdoors. It is protected against dust and exposure to water, but should not be intentionally submerged or operated underwater.
