For Sale: Battery Combiner 50 amp

[osirissail]

Amongst my spares I found a brand new, still in the sealed package, West Marine Battery Combiner 50. This is a small self contained relay unit set to combine batteries when the voltage exceeds 13.3 volts DC and separate them when when the voltage drops down below 13.3 vdc.

Excellent way to keep house and engine start batteries charged in small boats. New cost for similar item is over US$100 and I will let it go for US$50.
