I was talking with the guy winterizing my boat about a second battery and he sent me some install pictures. Most look like yours except for the attached. When I researched the VSR it the pic, it said it was necessary to charge both batteries at once. Did you have any charging issues or do only charge one per time? Thanks.

Always nice to actually attach the pic!

I usually run both until I park, then I will turn off then switch to one of the batteries if I am sitting a long time running the radio and stuff

I recently had a second battery installed in my 2012 Seadoo Challenger 210. The installer did and awesome job-looks almost factory.

Here are a few pics....

The factory battery in black, new X2 battery on opposite side, and new battery switch with position 1, 2, off and 1&2.

Was told to run battery 1 going out and while using radio, etc. while out. Then switch to battery 2 coming back.

Love the peace of mind this gives me while out with family!!!!

This is an excellent write-up. I have a few questions. First, how deep did you set the drill stop? As you mentioned, I dont want to drill through the hull. Second, what year is your boat? I dont know if I have that space available on my 2012 180SE. Last, does the additional battery weight on that side of the boat have any negative impact on how the boat naturally sits in the water?

The only difference from what you show is that I may use regular aluminium pop rivets and liquid nails to hold the battery tray in place. Hopefully my Perko dual battery switch fits the original OEM holes.
