I have a kind of interesting view on this. A Lot of Tige owners are looking to move their batteries FROM the very spot you want to move yours to, in order to make room for custom surf sacs. So why do you want to move yours? i will say though, that adding a house/stereo bank (extra battery) with an ACR/VSR, will have little to do with the location of the original main/starting battery. Example: i did a stereo bank in an 05 Tige 22V. We left the two original batteries with multi-battery switch as they were in the rear port locker/transom area and added two group 27's in parallel in the starboard mid-ship storage locker dedicated to the stereo. These banks are combined with an ACR and also have an on-board charger for maintenance. You need to account for the length of cable and load it will carry, but yo do not need to move the original batteries just because you are adding a 2nd bank.
