This is our custom made dual bank lithium marine waterproof charger. It has Bank 1 for 12v 10A lithium batteries and Bank 2 is 36v 10A for single 36v lithium batteries! Even when running 2 of our 36v batteries in parallel this one charger will charge both at the same time! This charger is 100% waterproof and can be mounted onboard your boat as you normally would with marine battery chargers!
This charger has built in low voltage cut off charging activation with a push of a button. This means when you run your lithium batteries all the way down they will reach what is called low voltage cut off, when this is reached the BMS (battery management system) basically turns the battery off at this point showing zero to little voltage to where the charger doesn't recognize that there is a battery connected. The activation button adds a short pulse charge into the battery waking up the BMS and allowing charge to start entering the battery.
