Range Extender 29.4 V / 7 A watertight (charger via alternator, 24 V batteries)

The REBELCELL Range Extender is an alternator charger designed to optimize the autonomy of 24 V lithium-ion batteries. It allows you to recharge these batteries directly from your outboard engine’s alternator while sailing, thereby extending the operating time of your marine equipment.

This Range Extender delivers an output voltage of 29.4 V and a maximum current of 7 A. These specifications are optimized for efficient charging of REBELCELL 24 V Li-ion batteries.

Yes, the Range Extender has an IP65 waterproof rating. This means it is designed to withstand marine environments, being protected against dust and water jets.

The Range Extender includes multiple protections for safety. It has an appropriate charging profile for lithium-ion batteries, overcharge protection, and overheating protection via dynamic thermal control.

To protect the boat’s starter battery, the device only begins charging the service batteries if the starter battery voltage exceeds 13.2 V. It also stops charging if the voltage drops below 12.8 V, preventing excessive discharge of the starter battery.

Yes, the Range Extender is designed to automatically stop charging when the service battery is full. It also autonomously adjusts the alternator current for optimal charging.

The Range Extender is a DC-DC charger. It converts the direct current (DC) from your engine’s alternator into a direct current suitable for charging your 24 V service batteries.

The Range Extender is equipped with overheat protection. Dynamic thermal control reduces or stops the charging current if internal temperatures rise too high, ensuring its longevity and the safety of the installation.

No, the Range Extender is compatible with traditional lead-acid starter batteries or LiFePO4 starter batteries. If you are using a LiFePO4 starter battery, a minimum capacity of 50 A is required.

This Range Extender is specifically designed to recharge 24 V lithium-ion batteries, including REBELCELL 24 V Li-ion batteries.

The Range Extender is compatible with outboard engines fitted with a 12 V alternator supplying at least 17 A. This generally corresponds to engines of 80 hp and above.

The Range Extender requires a 12 V alternator supplying at least 17 A. Low-power engines (typically less than 80 hp) may not have an alternator powerful enough to meet this requirement.

The Range Extender works with lead-acid starter batteries or LiFePO4. For LiFePO4 batteries, a minimum capacity of 50 A is required. Additionally, the starter battery voltage must be above 13.2 V for service battery charging to begin.

The Range Extender is compatible with engine brands such as Honda, Mercury, Yamaha, and Suzuki, provided they are equipped with a 12 V alternator supplying at least 17 A (typically 80 HP and above).

The Range Extender is a DC-DC charger designed for integration into your boat’s electrical system. Installation involves connections to the alternator and batteries. It is recommended to follow the user manual instructions for correct and safe installation.

Thanks to its IP65 waterproof rating, the Range Extender can be installed in marine environments where it may be exposed to moisture or water spray. It is nonetheless advisable to place it in a well-ventilated and accessible location for potential inspections.

Yes, the Range Extender is an alternator charger. It is designed to be connected directly to your outboard engine’s alternator to draw the energy required to recharge your 24 V service batteries.
