My boat has been sitting a bit lately (winter here) and I've been noticing that I haven't been able to really get my batteries as full as I would like using my poxy K-Mart style battery charger (2A). Well turns out it's totally goosed and only putting out 11V so in fact been flattening by battery's every time I use it.
Had a look around at what to get and found this digital style charger that thumps out 24A on boost then comes back for trickle. Nice. Its got a nice chassis so I can mount it to the wall of the garage and create a permanent loom in the boat for connection. I've wired up jumper set as well for charging the truck if needed.
