I have two reedy wolf pack 3600mah 6 cell battery packs that I use for my e-maxx. I've had them since last july and they seem to be heating up a little more than usual. It seems like only two cells are hotter than the rest and my run times change alot about every two times I run them. Also They are false peaking more than usual and seem to start out slower then have a power blast, then slow down to normal running action while I drive my maxx.
I run my maxx in water usually whenever it rains and theirs no rust on the cells and they seem to have good exterior condition.
I want to take the packs apart and discharge each cell individualy then reassemble the packs in sxs form. I use a dynamite twin peak ac/dc charger.
These are the batts I use- http://67.199.85.166/main/productdet...ory=5005.xxxxx
Questions-
-I dont know really how your supposto take apart battery packs. Is there a certain way to take them apart without damaging the cells.
-Is this ok to do?
-What method should I use to discharge the batteries. Can I hook up a motor or a light bulb?
-If so, what voltage per cell should the cells be at after discharging.
Any help is gladly appreicated.
 
The cells should be at .9 volts when discharged. Your idea may work, but a normal cycle or 2 is usually all they need to spring back to their peak performance. More than likely, you have some bad cells. I could be wrong, so wait until some others chime in. Depending on how much you run your Maxx, their life may be expiring.
 
So if I take the pack apart each cell should be at .9v. I have a voltmeter so this shouldnt be hard. I'm not really sure what a cycle is but I may just go ahead with my idea, but I'm not sure how you disasemble the cells. How do you do this?
 
The only way is to cut the shrink wrap. If your careful, you can separate the cells with out breaking the tabs. Not sure what to drain them with. Your best bet would be to dump each pack to 5.4 volts monitoring them very carefully as to not go any lower. The packs voltage will rise after being discharged. Discharge them repeatedly until the pack stays at 5.4 volts. Don't go any lower or you could damage them. This way there is no disassembling of the packs. Then charge them, monitoring the temps. Cycling simply means fully discharging the packs and then fully charging them.
