pro peak constellation charger

**Danjr1** · 19th May 2011, 19:10

And on the discharge, the battery voltage is dropping below 16.8v?! But that's on the nimh automatic setting rather than a custom setting

any help on this would be great! im tearing my hair out here. its reaching a peak of around 18.5v then the charger is cutting out. its discharging down to 16.6v approx. weirdly, the fan is staying on during charging which it has never done before?!

on my constellation the fan is constantly on when charging a high cell'd pack like my 24v and isn't on at all when charging my 6v (when charging both at the same aperage)

I really can't work out?! If I can't get it working, I'll have to bring it down to Guildford for some help

i'll have a look at it at guilford if you want but i'm by no means an expert, i've only been using the constellation for about 2 months now

Thank you. I'm sure it's only something simple but I can't work it out at all!

what supply is it ?

The supply is a maplins 12v 3a supply. Never had any problems with it. Another weird thing it's doing is that I set the limit to 3a during charging but it creeps up to 3.01a. Couple of minutes later it turns off but it never went above 3a when charging the 12v battery. I've separated the packs now and am cycling them and I've had no issues at all?!

In the past ive had problems with supplies dropping the output voltage a bit low so the constallation charger cuts out,
normally due to cheap supplies !. All of my constallation chargers charge a bit more than you ask it to never worked out why. you said you have now seperated your packs to charge and they are now ok, how long were they charging for ? im wondering if the supply was getting too hot ?
