Optimal charging profile: the Range Extender converts the alternator charge current to the suitable charge profile for your Rebelcell battery for safe charging.
Starter battery discharge protection: the microprocessor controlled battery seperator ensures that charging of the Rebelcell battery only takes place after the starter battery is full.
Overcharge protection: limits charge current automatically when battery is nearly full and shutdown if battery is full.
Temperature protection: dynamic thermal output control' feature limits (or stops when required) the charge current if temperatures are too high.
Short circuit and reverse polarity protection: automatic shutdown with short circuit. Reverse polarity protection only on input (not on output).
Warranty: two years.
