Weak generator battery

[Gregory OConnor]

Shane, sounds like a good device for my three bank system. Is the
blueSea able to pass 79 amps? Or return pass the request amps of a
failed start using aux "combined"??? the mfg calls it a charging
link. recharging a genset battery should draw no more than 20 amps.
with a good starter the momentary "combined" to start should not be
needed. I would think 79 amps would cook the BlueSea and the only
time there would be a big cross would be using aux to make a start
of gen or the detroit with compramised starters. I now use mini
alligator clips and 14 ga wire to charge my add on genset battery
and have no issue unless I drain the battery when boondocking by not
unclipping a clip. I think charging and starter issues begin with
overuse of momentary aux "combined"????
