The cells come in 3.3V, 2300mah. So what you need to do is connect 4 cells to make to whole pack 6.6V, 4600mah. So 2 sets connected in series and those 2 sets connected parallel (If I'm wrong, please do correct me).

My questions:

-Which charger charges with 10 AMPS or more and is reasonably priced (preferably with display!)?
-Do you really need to balance the cells and how do you do that?
-How do you connect (if needed) the balance cables if soldering my own cells?
-Some other tips and tricks or facts?? All are very welcome!

-Right now I use a MM Cell Master (not suitable for A123) and I have access to a Robitronic Overloader 1. Is this one suitable??


A lot of questions, but I hope most of them will be answered.
Just to be clear, I'm not looking for a lipo versus A123 or Sub-c discussion, becauce my mind is set on these cells because of the earlier mentioned specs.

Additional information: car: Tamiya TRF416, LRP Sphere TC.

Thank you in advance!

Hyperion looks good and is reasonably priced.
@ DLS II: Could you be a bit more specific please? What do you mean with MEC SPT? When I google it, looks like something with De Walt...I know that De Walt uses A123 cells, but are these usable?
@ Eddie_E: looks like a good charger, but would still like to charge with higher amp rate.

Any more suggestion or any other complementary information?

Thanks.
