In my case, I have a relatively low output alternator (55A) charging two
battery banks. House consists of 2 6V golf cart batteries in series with
210AH capacity. The other is a conventional starting battery. If alternator
is charging House (which may be down to about 50% charge) and just reaches
13.3V, what happens when the combiner contacts close? Presumably it adds a
load to the alternator and the voltage drops a bit below 13.3v? Then,
wouldn't the combiner disconnect and keep repeating the cycle? The BEP site
warns against this and provides sizes of alternator/battery to prevent
cycling. Is there any built in protection against this in your unit?

Thanks for your interest,

GBM

We made the West Marine battery combiner for them for 13 years but now
are using Defender as our primary retailer - you will find Defender's
prices are much better than WM had. I don't know what is wrong with
other combiners but we've not had any of the problems you describe with
over 26,000 sold and all on UNCONDITIONAL warranty. If there were a
problem we surely would have heard something by now.

You can download the owner's manual from
http://www.yandina.com/acrobats/C150Data.pdf
and you will find a number of suggested schematics.

You can contact Defender at

I will be happy to answer any questions you have.
