Wich NIMH battery for brushless setup?

[Jasper]

Hey guys,

I need some some advise for new batterys for my J-truggy. The motor is a wanderer A class 12XL with a warrior 9920 esc. I run a xushobby ubec with standard HPI servo for breaking and BMS 630 for steering.

In Germany I can get good cells for an reasonibly price. I always have driven GP3300 cells on my brushless setups. But there are new cells now. The IB3800 en IB4200 seems to be a good cell with a nice price tag. Can the IB cells handle the power off brushless? Or should I stay with the GP3300 cells? Are the IB cells also bigger than the GP3300.

Thanks.

The ib's carry a nice voltage. But personally nothing beats the gp3300's. Durable, long life, nice power and wont burn on you!

IMO, the 12XL is reasonably gentle on batteries due to its low max current draw (55A) as compared to some of the more powerful motors. As long as you don't use cheapie batteries, you should be fine. Higher capacity batteries will increase runtime.

If you dont mind me asking, hows that A class motor working for you? What happened to your old gp3300's?

Thanks guys.

@ Sylvester,

the A class motor is working really good for me. In my buggy I got 40/45mph and 30 minutes runtime with crappy GP3300 cells. These cells are dead now. Because I ran the buggy with fresh batterys, wich were 40 C and the outside temperature was 30 C. So after a few lines running, the batts began to smoke. They are toasted. The motor is running really smoothly. The flat grinded spot on the shaft is also really helpfull to attach the pinions. And the big heatsink provides a good transformation for heat. The runtimes are really amazing with this motor. I am really curious on how the motor perfomances with new cells!

I would go for the IB's.

[Sylvester]

IB's or Gp's, ib for more runtime for sure, gp for reliability. Cant go wrong either way!

[Jasper]

I just ordered 20, GP3300 P/M 2nd generation cells. I allready got 30 minutes off runtime. With crappy GP3300 cells. So with new cells the runtime will be increasing. So dont need for more mahs. And my battery slots are designed for the GP3300. So I don't have the issue with maybe a hard fit with the IB's.

Thanks for the advice!

[Sylvester]

Nice! Where you order from??

I have had good luck with gp 3300 gp 3700 and ib 3800. I think I had little better performance from the ib 3800.

I would actually recommend the GP4300's. Or Nickle Metal Lipo ;):D

[neweuser]

Lipo would be nice if you could afford them, less weight, more speed, and if you take care of them, they take care of you! Otherwise, it depends on what you want to run. Consider weight a factor when getting more mah. so it depends. IMO, ib 3800's. i have two 7 cell packs that i have been running real hard for a long time. Also have two 8 cell packs. I was thinking 4200's, but the weight backed me away. IB 3800's are a good in between, good runtime, and are RELIABLE as well...So it depends on what you want to run...

[squeeforever]

I wouldn't choose the GP4300's. They don't hold there voltage well and I haven't heard anything good about them yet...

My IB3800 started poping a week or so ago and one acually burst into flames and blew up yesterday but thtats after id gad them a year
