Rebelcell is a Dutch battery manufacturer known for their high-quality products. Rebellcell's lithium batteries are designed to meet the power requirements of even the most demanding boating, sports fishing, and hiking enthusiasts – in a lightweight and environmentally format manner. Rebelcell's extensive range include 12V and 24V lithium batteries, chargers, as well the necessary wires and accessories.

Rebelcell lithium batteries are amazingly compact and lightweight compared to traditional lead-acid batteries. The high performance, deep discharge resistant Rebelcell lithium batteries are perfect for providing power in demanding conditions on boats, for example for electric bow-mounted and outboard motors, sonars, audio equipment, etc. Because the Rebelcell lithium batteries can be utilized almost up to their full nominal capacity without damaging the battery, you can replace your traditional lead-acid battery with a lithium battery with half the size. For example, in terms of performance, a 12V 50 Ah Rebelcell lithium battery corresponds to a lead-acid battery with a capacity of up to 105 Ah! The integrated voltmeter allows you to monitor the charge easily and reliably as a percentage, bars, or voltage (not included in the 7 and 18 Ah models).

The Rebelcell lithium batteries should only be recharged with Rebelcell chargers specifically designed for the batteries. You can also connect a Rebelcell battery to your boat’s starter battery for charging while on the move with the Rebelcell Range Extender charger (12v 70–140 Ah and 24v 50–100 Ah). The built-in battery monitoring system (BMS) of the Rebelcell lithium batteries protects the battery against deep discharge, over voltage, as well as low and high temperatures. Rebelcell lithium batteries are safe, maintenance free, long-lasting (estimated useful life 10 years), and high performance batteries for powering various gadgets on your boat.
