Ive just finished building my 12v 3800mah battery from 1.2v sub-c cells but the instructions with this charger are a bit confusing. anyone know what they are doing with one of these? the help would be much appreciated!

Ok, I can help you out with this: For basic charging, do as follows:
You should have a screen that has battery type, number of cells and amp rating. Press 'Setup', and Battery type should start flashing. Press up and down to select battery chemistry, and press setup again to move to the next one and change that to suit.
Press down, and you should have a screen marked charge mode. The details you put in before should be there. Press setup again, and you can select the rate of charge, and press setup again to exit. Once you have the battery details and charge rate done, connect the battery and hit enter, and charge mode will start. It'll beep when its done.
im using the automatic settings at the mo to go through a few cycles.
dave, dont suppose you could tell me the settings i need to input for a 12v 3800Mah 12 cell battery? i just cant get along with the thing!
Hey Dan
The description in my first post should have produced the desired result and have your settings ready for charge, Whats the problem exactly ? Drop me an e-mail and I can probably talk it over on the phone or something if you are having problems still.
i got most of it. what charge and discharge rates do i need for it?
I charge my 3300mA packs on a fast charge of 3A, but for a slow charge, anywhere between 1.5-2A. for a 3800mA pack, 3A will be a good quick charge rate. As for discharge rate, I've never actually done it to my own batteries, but I wouldn't discharge them at more than 2A.
whats the 5mV/C bit on the charge screen? and im guessing the ....V/cell means the voltage of each cell (being 1.2v)?
I beleive thats to what tolerance you want each cell charged at. I've never changed it, and not had any problems, so :)
ok, ill have a go. im using 16 swg wire, that ok? sorry about all the questions, im ok with the mechanical engineering side but electronics is not exactly my speciality!
