Default Competition electronics linear turbocharger

Hi guys, I have this really old charger I was going to use for a couple weeks before I got a new one because my other one died.. I'm trying to charge 5 cell receiver batteries I think 1600 mah. Just wondering what settings to put it on. I put it at 2 amps and then I goto a screen that then it let's me choose 1c, 2c, 3c, 4c, 6c, And 7c.. aren't I supposed to be charging at 5c? Because when I goto the next screen, whichever number c I picked is how many cells it says it has.. any help would be appreciated! Thanks.

it depends on the battery it self
I use 1 amps, 1C

some can be charged at more than 1C

It's just an ofna 1600 nimh hump with 5 cells (or 5 batteries).. So if I do 1c at 1 cell and 1 amp then I should be good until I get a new charger?

why not download the manual and do it right http://www.competitionelectronics.co...-products.html make sure the charger is in the right mode as it mine had Lipo or Nimh mode as in this case I would think the C is for cells (Nimh mode) not charging rate I used to charge my receiver packs at .75amps

That's not what he has. He has the old (much smaller) linear turbocharger. Lipos didn't exist back then.

I have the same charger, use it occasionally to charge starter box batteries and receiver packs. 5c is the number of cells. Charge between 1 and 2 amps and let it rip.

Nope.

You're using the Lipo formula for a nicad pack. Nicads have a quirk where if you charge at a higher rate, the pack voltage will be higher but you will lose run time. That's good for a race pack but not a receiver pack.

Charge the pack at 1 amp and you'll be fine. If you're at the track and you're in a rush you can charge at up to 2 amps with no issues.

The charger was not designed to charge NIMH cells. You must watch the temp. of the pack, as you charge. The charger will not shut off after the battery is peak charged. Be Careful!!!!!!

It's not a problem as long as you aren't charging them fast, like over 3 amps. Does just fine.
