Hi Pete,
If the batteries are shot, don't they get warm
with hard charging? Danny's original message says the batteries are not warm.
Maybe he is deep cycling the battery bank.
Cheers, Russ

This may be an indication that your batteries
are shot. The charger is working to give them a
juice and theyre just not having it. Take a
look at them before you change your
charger. But also look for loose connections.

Hi Danny,
I like how you find it goes grey, most of your fellows call it gray. :)
Anyhow, the meter pegs over 30 amps, let's say
35 for this discussion... and at 15 volts we're
looking at something near 500 watts to the
batteries. If it's a 90 percent efficient
battery charger then it has to dump 50 watts or so into the surroundings.
For perspective and giggles, turn on a 40 watt
light bulb and see how long you can hang on to it. Yow!
A machine at 160 F, you can touch but not hold
your hand on for very long, 180 F is tolerable
for less than a second. From your description, I
suggest the battery charger is operating around
150 F if you can put pressure on it with your
hand. That is not a worry if it's like that for
a few hours. I am also assuming ambient cooling (no fan).
Cheers, Russ
Sweet 35 mk-1

Hi guys,
When I turn the battery charger on it greys very
warm. The Guage pins all the way past 30 amps.
It is not too hot to touch but too hour to hold
your hands on for very long. The batteries are
not warm and seem to have taken some charge over a couple hours.
It's this normal? I don't like that heat...
