After a discussion with the battery guys, Lithium Ion batteries are different and you need to change the mindset of how we have traditionally charged. The long and short is yoiu do not trickle charge....you discharge as much as possible to preserve the life of the batteries. our plan is to store the charger and pull it out when we need to charge. It will get warm while charging and we want to monitor first before any permanent mounting. In addition, you hook it up, charge the batteries and then disconnect. You do not leave a charger connected to the batteries. It is also recommended that you unplug the trolling motor from the batteries when you are not using or planning on using the trolling motor.
in a nut shell, charge the batteries before a trip and do not charge until you ready to go again. And only do that if you have discharged them to about 80% or more. We are new to these batteries
