Another E-Slayer hits the Short Course

[E-Revonut]

3 of my 4 600mah packs went way out of balance 2 weeks ago, eos0606i wouldn't do anything for them on it's own. Made a harness to connect from balance tap to main charge leads and did a 1A discharge on the cell with higher voltage and checked it every few minutes till it was close. Now I have a few more runs on them and they seem to be doing ok. Just running hot in the E-REVO battery compartments.

That is the best way to get a cell back up without excessive balancing. I wish the chargers would charge each cell individually, and vary the amp rate to get everything equal. I can only imagine the amount of circuitry required to do that, basically have a bunch of 1s chargers connected to a "brain"...

The problem is that the balance leads would have to be large enough gauge to handle 1c charging, which could easily be 6 amps... It would be a killer charger! And pricey...

I keep my little 5i hyperions to charge individual cells. If someone sends me a pack with bad cell(s) the other cells can often be well out of balance. I seperate all of the cells and charge them at .5-1 amp rates until they top off. If the cells are not puffed, but under 3v it often takes a few trys to get them to reach full capacity. Almost seems like they "false peak" (old nimh terms, HAHA) sometimes. Have to let them sit and stabilize. Slow charging with a low amp rate works best.

Yeah, way off topic now...

And to answer the original question, do you have the clutch shoes setup as traxxas recomends? Tekno says to flip them over, so the trailing edge engages first. That should make it engage faster. Or remove the spring altogether, but that may be too fast...

Yes I did

I just may need more Cells
