FAQ
Is 12V(14.6V) 40Ah lithium battery charger waterproof?
No. The 12V(14.6V) 40Ah LiFePO4 battery chargers are not waterproof and should always be used in a dry environment.
For trolling motor batteries or marine household backup batteries, we recommend pairing them with a waterproof charger to ensure safety and long-term reliability.
