Battery charging

[Joe1967]

Hi. I have a 2021 31MB we bought last summer. It came with one battery, and I am planning on adding a couple more deep cycle 12V batteries. I was wondering if I need to do anything different to the charging system that charges the batteries when plugged in to shore power? I expect it to take longer. Thanks.

Get an upgraded more powerful three stage charger
Consider 6 volt golf cart batteries

Nothing more than cables and battery boxes needed.
Plenty of reasons to upgrade.

My first year I threw in 2 more cheap 'deep cycle' batteries, and killed all 3 learning how long we could go. I also learned how bad the built in battery monitor is. Now we're rockin as many lithiums for twice the power.
