CFX3 Coolers
What is the battery protection system?
The battery protection system is a feature of your CFX3 that actively monitors inbound DC voltage and turns off the cooler if it senses low voltage.
This feature is designed primarily to prevent the cooler from draining your vehicle’s starter battery and leaving you stranded while out on the road. It also prevents damage to accessory batteries
The battery protection system has three levels: High, Medium and Low.
