Hi all,

I was wondering weather someone can explain if this is correct.

I have a sigma pro peak charger its the same as the prodigy pro peak2 or so I have been lead to beleive but just in a different case with the advantage of 240v as well.

My query is with the discharge funtion.
If I want to do a discharge on its own I am able to set the cut off voltage for the pack I am using and it will only take the pack down to the cut off voltage you input which is feasable.

But if i use the charger in the cycle mode allowing it to discharge then charger it seems to disregard the input cut off voltage and take the pack down much lower than what you have set at the discharge funtion.
It seems to take the pack right down to a level that would seem to low and dangerous to the pack as I have heard you should not drop the pack anymore than 0.9volts per cell for a nicad pack.

Anyone know if this is how it is supposed to work or is this common with most other chargers to. I am guessing that it is trying to exhaust the pack but is this funtion safe to use on these packs.

Interested in what you guys have to say and what your observations have been with similar chargers. Am I worrying about nothin or do I have a real concern when using the charge/ discarge funtion.

Thanks Guys

There's a bug in the software when cycling as you've found out.

As far as I know, nothing can be done apart from NOT using the automatic cycle feature. It's never been much of a problem for me because I never leave charging/discharging unattented.
