1992 V20 - Looking to add a second second battery

[Petrus]

My 1992 V20 has a single battery located under the baitwell in the starboard side of the transom- it looks like there is plenty of room to add a second battery- The 1992 v20s had second batteries as options- anyone know where the battery switch should be located? The transom looks like the obvious place but would like to know before I start drilling. Thanks

Pics would help but, my buddy has a 1992 Center console and he has two batteries, switch, and charger all tucked into the starboard well area.

TX Airslot- boat is under wraps for the winter- will post pics once I get her uncovered and ready for the water. Spring can't come fast enough.

When I bought my 94 center console both batteries were on the same side . I move one to the other side where is shares space with the oil tank . I wanted to even out the weight as much as possible .

My '91 has the battery switch and one battery on the starboard side and the other battery on the port side under the rear hatches. You had to remove the liner to get to the switch so I installed a new hatch near the floor for easier access. I removed the oil tank from the port side because I went to a 150 Honda 4-stroke and installed a wash-down pump. I now want to install a set of Bennet trim-tabs and dont' know where to install that oil tank.
