Features

Lightweight

RELiON lithium batteries provide more power than lead-acid batteries and are typically half the weight. Boosting both performance and agility on the water.

Long Life

RELiON lithium batteries provide up to 10 times longer life than lead-acid batteries, and they still provide 80% of the rated capacity after 3,500 cycles.

Partial State of Charge Tolerant

Partial charging does not affect performance quality or battery life. A low self-discharge rate means worry-free storage so even occasional users can be assured of reliable performance.

Maintenance Free

Plug, play, and charge. No watering, no corrosion.

Lower Total Cost of Ownership

Changing batteries less often means fewer replacement and labor costs.

Highly Efficient

Fast recharge time and a 99% efficient recharge process, which means less wasted electricity.

More Usable Capacity

Lead-acid batteries are typically sized up to two times your energy needs to account for extended periods without sun and less usable energy with higher rates of discharge. Plus, you are typically cautioned to limit your use to 50% of the rated capacity, as using more can significantly reduce performance. Lithium batteries provide 100% of their rated capacity, regardless of the rate of discharge. And, you can use it all and still get substantially longer cycle life.

Extra Safe

Inherently safe chemistry coupled with the BMS and protective features at the individual cell level provide maximum protection.
