Re: pro peak constellation charger

lower the charge rate to the nicad so you only use 3 amps from the supply ,
hi dave !

Re: pro peak constellation charger

Tried that. It's saying that the output voltage is too low?

[razerdave]

Re: pro peak constellation charger

That could well be the cause, I've had it happen when a fuse went on a power supply not rated for use with the pro-peak

Re: pro peak constellation charger

got it all sorted now. made a stupid mistake on the settings! 12c should have been 10c! thank you all for your help!

Re: pro peak constellation charger

Updated the battery to 16.8v nimh 4300mah but it's doing the same thing again! Discharge is fine but on the charge, the charger is turning off and on therefore cancelling the charge. It's a 14 cell pack so ive changed the 10c bit to 14c but other than that everything else has stayed the same (4300mah, 3amps max charge and 5m/vc or whatever that bit is!)
Thanks

Re: pro peak constellation charger

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

Re: pro peak constellation charger

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?!

Re: pro peak constellation charger

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)

Re: pro peak constellation charger

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

[jonny]

Re: pro peak constellation charger

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

Re: pro peak constellation charger

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

is the charger screen turning off or is it the 13.8v supply turning off to the charger ?

what supply is it ?

[Danjr1]

Re: pro peak constellation charger

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?!

Re: pro peak constellation charger

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 ?

Re: pro peak constellation charger

Say 20 minutes? I'm charging the 4300mah 4.8v pack now and it's currently on 4360mah and rising......
