I have added a dual battery in my XP41K. there is a big hole in the second box area but the battery is laying right on it. Also I have not pulled the factory battery yet I’m waiting for everything to dry out first. I did pull the second battery and it was holding water to above the batteries. I was thinking about drilling some more holes in there but I have full skid plates and I’m not sure whats up under there and until I see my buddies I’m afraid I’ll end up drilling into something or snagging wires etc.. (I have a history of drilling into things). Also thinking about adding a couple spacers under the battery so it sits up off the hole but as much mud and grime was in there the hole was plugged anyways so I doubt it would have drained with it lifted. I cut the little flange that goes between the factory battery area to the secondary battery area so water would drain out of there into the secondary compartment.

Any other ideas besides lifting battery and drilling a couple more holes?
