People chime in with suggestions about making a tilting battery tray...

Quote:
If that rear seat folds forward you could put the batt rack on hinges and fold it forward as well to get at the spare tire. might be a bit heavy but how often do you need a spare anyway.
That's a neat idea.

I'd have to get some good leverage to fold it forward though, since the rack, batts & cabling will weigh around 280 lbs together. But that's not impossible.

Another thing I'd have to check is the angle the batts need to be at to get the tire out from underneath - don't want to tip them so far that acid could leak from the caps.

(periods are your floor, underscores are your battery tray, seatback is to the left)

Then you can move the batteries forward without tipping them at all. The leverage wouldn't have to be as much either.

Sorry for the ACSII art. I hope it makes sense.

Cool idea, especially if counterbalanced somehow. How much cable flex can you afford though? You don't want to change your flat tire only to knock a cable loose... or worse, break a terminal.

BTW, very elegant illustration, that ASCII art.
One of Wayland's Datsuns actually has an entire rear tray that slides in and out of the trunk area electrically.

That parallelogram hinge idea is nice. But truth be told, I'm going to stick with plan A just to keep things moving along. I already work slow enough - don't need to be re-engineering things on top of that!
