[C320-list] FW: Re: Are 6V Batteries Superior To 12V Batteries For DeepCycle Applications?

Robert,

Both 4D's and 8D's are approx. 21" long. 4D's are 8.5" wide while 8D's are 11" wide. Given the compartment size and geometry, I doubt if you have 8D's. If you do, however, let me know so I can add it to my list of C320 Design Changes. Your hull # also.

Thanks.

I've looked, but other than they're HUGE (perhaps 2-3 feet long?), I saw no markings on them.
