The project: New batteries. The ones that came with the boat weren’t holding a charge as well as they should be.
The considerations: Upgrade? Add another bank?
The outcome: We decided to keep things simple and replace with Trojan T-105 deep-cycle flooded golf cart batteries. Why?
- It’s a tight fit! A major re-configuration of the space would be required for different sized batteries.
- Price. Golf cart batteries are $180 (CAD) each.
- On Hydroquest we had to replace a battery down in Mexico… We learned that it’s nice to have something that is fairly standard and available in other parts of the world.
- We plan to set up the boat with charging systems to keep the batteries nicely topped up at all times (try not to draw down more than 30%), so a huge storage capacity is not so important to us.
The outcome: 450 AH. Two banks, each with two 6V batteries in series. Plus a separate starter battery for the engine.
