I have a twin battery set-up on my buggy, using a ‘True’ battery isolator:

As I don’t use the buggy as often as I’d like (pleeeeeze let me retire!!), I wanted to keep them both topped up with a reliable battery tender.

I wrote to those nice people at CTEK and told them of my setup. Although they make twin battery chargers, they suggested I use the CTEK MXS 5.0 wired to the primary battery.

I also installed and hard-wired a pair of their battery monitors – they flash different colour LEDs according to the remaining charge in each battery.

The monitors also act as a port to charge each battery:

By attaching the CTEK MXS 5.0 to the primary battery, the algorithm of the tender coupled with the True isolator/connector will ensure that both batteries are maintained.

That’s the theory and it’s working so far!
