I bought new Tenergy 5000 1.2 volt nimh cells. I made 1 - 8 cell pack and 1 - 9 cell pack. I soldered everything and used the deans bones to connect them. Everything seems to be connected good and i'm charging with the Prophit Plus 2 charger. The 4600 7 cell packs that I bought have twice the power and last twice as long. Did I buy bad batteries? Is the charger I got to small for these packs? Do I need to do anything special to the new batteries, they have went through a few cycles and still suck.

Did I ruin the batteries? What charger / decharger should I get?

I would appreciate any help you can give me. I know i'm new and a pain but trying to get these working.

Nope the tenergy's are just cheap low end cells....

That was very helpful

Can you point me in the right direction? What cells do you reccomend?

sorry i was tired...Anywho Elite cells are good so are Ener-g cells are awsome and IB cells
I just had a custom pack made by Cheapbatterypacks.com with Elite 5000mah's for $47.

Tenergy are lower end cells but should still last as long as the others. Did you do 2-5 forming cycles charging at 1/10C?

i have a prophet charger and lets just say i dont use it anymore- mine wiould heat the cells really bad when charging.

So i'm getting a new charger, any reccomendations?. I guess I want to be able to charge Lipo''s, 9 cell nimh packs and charge and discharge>

I didn't form the batteries. I will get a new charger and do that but is it too late? I guess i'll form them and hope for the best.

Thanks for the help.

Is there any way I can change my post count to say 423,835 posts?? So I can be considered cool and worthy of assistance?

The best bang for the buck quality charger I have is the Thunder Power 610C. It will charge ANY type of battery including up to 6S lipos at a 10amp charge rate. Comes with a built in balancer for TP and Align taps. Needs a power supply though.

Thanks for the info I got the Thunder charger. I have one more question.......

I made a Tenergy 9 cell pack so I think that is 10.8 volts??? I cycled the pack 2 times discharging to 9 volts and it automatically charged it to 13.6 volts, does that sound right??

I now know I made a bad choice on the battery selection. I bought a Lipo pack, just trying to get the ones I made working so I can give them to my nephews.

Thanks for any help.

Joe

Thats about right it took it down to 1 volt per cell(.9v is the lowest you would want to go)
And the finish volts is always higher...If you let it sit for a while then check it again the volts will be lower.My 7 cell 8.4v pack is around 11.5 volts fresh off the charger.

You are doing everything right.

I bought the Onyx 230 by duratrax it has a 10 batt memory adj from .1-7a charge, good display showing amps,charge rate,and mah for charge and will charge all batts. only about 80.00.

Is that truck in the photos yours? If so that is one sick truck, is there anything stock left on it?

Thanks for the help, I think i'm finally getting it.

Ya the truck is mine, its a ( or was ) rustler. Nothing is left from the truck except the motor and esc, nothing. I think I got a little carried away its kinda heavy now, but I liked building it. Its Fast Lane, Integy and I built a fair amount of the aluminum parts as-well. I think lighter is probably better but is still does pretty good.

So while i'm on the question thing.....

What would be the sickest 1/10 scale off road I could build, lighter this time. The fastest, most durable, well balanced for big airs, whats the best?

i hope this is on topic enough, i went lookin around to find out what the s in 3s 4s 5s etc.. lipo meant. that is explained here [link=http://www.rcslot.com/blog/lipo-batteries-explained-a-how-to-guide-for-lithium-polymer-batteries.html]3s 4s explained[/link]

and some information on charging, care, and safety with lipo packs. quite a few informative videos on them exploding under certain circumstances.
