If you NEED 2 use the red top.....put it under the hood.

If you have the yellow top under the hood....your goin backwards, it's a slow discharge battery.... (deep cycle)

Put the red top under the hood.....isolate the yellow top...and hope for the best?

if not isolated one battery will most likely discharge the other as both batteries will not charge the same... so one will always pull more current then the other.. so it would lead to early failure of one or both batteries.. but when isolated you wouldn't have any problems
