Rebelcell lithium batteries are incredibly small and light (even less than 70%) compared to a traditional lead battery. The high-performance and deep-discharge-resistant Rebelcell lithium batteries are suitable as power sources for applications requiring power in boats, such as for bow electric motors, electric stern motors, sonar devices, audio equipment, etc. Since the Rebelcell lithium battery can be used almost to its full nominal capacity without damaging the battery, compared to a traditional lead-acid battery, you can choose an even smaller battery to replace the same power requirement. For example, a 12V 50Ah Rebelcell lithium battery is equivalent in performance to a 105Ah lead-acid battery! The voltage meter on top of the battery can be used to easily and reliably monitor the battery charge both in percentage, current bars and also expressed as voltage (not 7 & 18 Ah models).

To charge Rebelcell lithium batteries, only specially designed Rebelcell battery chargers should be used, and in addition, the battery can also be connected to receive charging while driving with the help of a separate Rebelcell Range Extender charger (12v 35 ? 140 Ah & 24v 50 ? 100 Ah). The built-in battery monitoring system (BMS) of Rebelcell lithium batteries protects the battery from deep discharge, high charging currents, and excessively high and low temperatures. The Rebelcell lithium battery is a safe, maintenance-free, very long-lasting (assumed service life of 10 years) and high-performance battery for all types of boats as a fun battery.
