Detailed description
Detailed description
Designed for sailing, the Range Extender 42 V / 5 A waterproof from REBELCELL allows recharging 36 V Rebelcell batteries directly from an outboard motor’s alternator. This solution extends battery life on the water, enabling users to maximize their time afloat without relying on an external power source.
Charging performance and compatibility
The Range Extender delivers a capacity of 210 W with a maximum charge current of 5 A. It operates with an alternator input voltage between 9 and 18 V and provides an output voltage of 42 V, optimized for 36 V Rebelcell batteries. The alternator must have a minimum output of 17 A. This device is compatible with outboard motors from brands such as Honda, Yamaha, Mercury, and Suzuki, using a 12 V alternator. It can be used with lead-acid or LiFePO4 starter batteries (with a minimum capacity of 50 Ah for the latter). The Range Extender’s peak efficiency is optimized, minimizing energy losses. An optimized charge profile ensures safe and efficient recharging of 36 V batteries.
Marine integration and protections
With compact dimensions and a weight of 1.45 kg, the Range Extender is designed for permanent installation aboard. Its IP65 waterproof rating makes it suitable for marine environments. It operates across a wide temperature range. Connections are made via screw terminals. For system safety, the device includes protection against starter battery discharge, starting charging only when the starter battery voltage exceeds 13.2 V and stopping if it falls below 12.8 V. It also features protection against temperature (dynamic thermal output control), short circuits, and output overcharge/overvoltage. However, input reverse polarity protection is not included. An integrated LED indicator signals the charge status. The Range Extender is CE certified and comes with a two-year warranty. It does not provide input/output isolation and is not designed for parallel connection.
