M923A2 Battery Relocation Project

From your comment you are running (2) two 12VDC batteries wired in series to provide 24VDC power to the M939 vehicle. Both solar units would be wired in parallel with those two batteries. Here is a quick diagram of what I assume is your setup. Please verify the part number on the solar units before connecting.

Yes. Perfect, thank you for the detailed information. Very much appreciated.

Rubber tie strap to hold down the battries? At least use a ratchett strap.

I agree with Floridianson. Holding down 4 batteries with just 1 rubber bungee could be asking for trouble. Personally, I would have each battery secured with a battery hold down and rods. Yes, the maintenance time is greatly increased when servicing, but peace of mind making sure they don't move, even in a roll over, is
priceless. My 2 cents.
