I have a sailboat that I keep at a marina, so charging time is not that
critical, I guess. My old, old Nav Mar HDM 30 charger is frying my
batteries and I'm looking to replace it. I have a charging battery and
two 75 amp house batteries (in one bank). Can anyone recommend a
charger for me? Would the xantrex TC10 be too small a charger?

Thanks in advance,

George
