Before anyone runs out to buy a dual 6-volt battery box, here are some things to consider:
1. Even though the 12-volt battery box is near and partially under the hydrolic pump platform making it awkward to replace or service, dealing with the dual 6-volt box is more difficult.
2. The dual box must be loaded into the front bay to the left of pump and then slid under the platform to roughly the same position as the old box.
3. There may be some fasteners protruding from the floor of the bay with which to contend. I had to reposition the battery's ground cable.
4. When in position, there is no room to load the batteries, so you must load both the heavier 6-volt batteries, box and all into the bay and slide the box into position.
5. There is just enough room to attach the box cover which is secured by threaded knobs. It fits very nicely. This means doing a visual inspection of the installed batteries is very difficult when the box is in position under the pump platform.
6. If you have, or intend, to installed a nice wire shelf to the left and on the same plane as the pump platform (like the new Montanas), be sure to make it removable to facilitate servicing and/or replacing your batteries.
7. The box will have to be altered after you get it. holes for the bottom drain and the top vent will need to be cut and (if you choose) couplings will need to be epoxied to the case at those sites.
Conclusion: You have to be convinced the transition to dual 6-volt golf cart batteries is worth the effort. The box, itself, is far superior to the OEM boxes in the units. An alternative may be to install the box in an area of the bay with better access, but I didn't want to give up the space.
I purchased my box from another MOC member who had one more than he needed. The box I have is manufactured by Blue Sea Systems. You can order directly from them at
