My BPS two bank is still going strong. It is a 2000 year model. I recently sold the boat and just bought another one from BPS. If it lasts and works as well as the other one, I will be more than happy. So, I would recommend their 3 bank charger. Their chargers are made by another company, Pro Mariner I think and you can buy under that brand also.
Someone chime in if I got the name wrong, but it was something close to that.
