I use 2S A123 + 4300kv on my HB 12x. (T-bar)
Here is what I have posted before: http://bbs.rc-evo.com/viewthread ... p;page=1#pid1200958
this is just an experiment. the biggest advantage of A123 is the charging ability. I can use 10A to charge the A123 and it will finish charging in 15-20 mins.
the disadvantage of A123 is its large size and weight. The A123 just fits under the body. Also I will have to add a lot of dead weight to the make it balance.
If your car can fit 1s Lipo (or 2s lipo), it is better because of the light weight and small size.作者: Edwin 時間: 2009-9-23 12:45
Thank you for your reply. Could you tell me if there are any difference in terms of handling and acceleration between Nimh and A123?
Thank's a lot!作者: hardmankam 時間: 2009-9-23 15:18
I havent tried A123 and NiMh back to back using the same car.
BUT...
In terms of weight, A123 wins ... thus better acceleration, less tire wear
In terms of balance, NiMh wins ... thus better corning and handling
It also depends which 1/12 you have, you have a T-bar or Linked 1/12?作者: Edwin 時間: 2009-9-24 11:03
I have Xray which is a T-bar.作者: hardmankam 時間: 2009-9-24 14:58 本帖最後由 hardmankam 於 2009-9-24 15:01 編輯
For t-bar cars, all 3 types of batteries can be used. but the issue will be how to balance the car.
For linked cars, only lipo or NiMh will fit. The round A123 will not fit under the shock. (unless they create flat A123 like lipo or you raise the shock)
So for me:
T-bar: 2xA123
Linked: NiMh
FYI: Westerners are racing with 1S lipo now. So this could be the new standard.
