small lipo charging problem?
 
I have a trakpower vr-1 charger w/ the docking power supply. When I go to charge my small 2s packs it charges them for a minute or 2 then reads full , but they aren't. I have an eflite 800mah 2s that I charge at .8 amps and a venom 2400mah 2s that I charge at 1.4.I've tried charging cc/cv and fast charge modes w/ same results.wth am I doing wrong?

Doesnt sound like your doing anything wrong. What does it say your voltages are when done charging?

Sounds like you're using a powerlab? If so, try one of the default small pack pre-sets.

they jump up to 8.4 pretty rapidly like they are being charged at 2c but when I put them in remote only at 7.3 to 7.7

Do you balance charge them?

yes

My old radio did that too. After I fully charged my lipo then put it in the radio it only registered 7.8 and the charger said 8.4. Is it a spektrum? If so try a voltage regulator unless its a DX3R Pro, you won't need it

crazy nick, that's one of the best sigs I've seen in awhile..:lol:

shagino 06-06-2013 12:30 PM

Agreed. Great sig. My fear is she sells it and finds out how much I spent on it!

I have the same charger. Do you get the same result out of port 1 & 2?

shagino 06-06-2013 02:55 PM

You may want to ask this question the the TrakPower thread. A bunch of us in there have this charger and there's definitely TrakPower folks who can help you.
