I’ve cooked two sets of Trojan T-105 house batteries in my 2013 RoadTrek Adventurous RS on the Sprinter 3500 chassis. The stock battery separator lets the alternator dump way too much current (like 45 amps) into them while driving and warps the core. The Trojan's don't want more than 25 amps.
A DC-DC charger would solve the high-current issue by capping the charge at 20–25 A, and give me a nice charging curve, but I can’t find a good place to mount one. Most are 9″ or more and want a few inches of space around them. The area around the battery separator is too small for the DC-DC charger and I have concerns about the heat under the engine hood. The only spot I see is on top of the air filter box, which I’d rather not drill into.
If you’ve put a DC-DC charger in a Sprinter 3500, where did you fit it? Or have you had my battery issues and solved it another way? Pics and tips welcome!
