The mah rating is just how much 'charge' the battery holds. The thing you have to check is the cell count, 2S-7.4v, 3s-11.1v, 4S-14,8v. However you also have to make sure the 2000mah wont be too much heavier the 850mah. you will get a much longer flight time with the 850 but the weight will be an issue and so may the cg.
one of the cells voltage was 0.7. i tried to charge it but charger kept warning low battery and stoped charging after 5 secs charge. I tried severel times until charger stoped warning, at the end cells voltage are 4.20 4.18 3.70
Hiya I am running a Turnigy 5000 in my rustler, it doesnt quite fit, but u slide it as far as it will go underneath the ESC... it will stick up some, u cant use the Traxxas battery retainer on it, but I just got 2 cable ties and held it in that way. (BTW... now I cant keep my Rustler on the ground or in a straight line! AWESOME!)
12 thumbs up!

Very good batery, I used it in my easystar FPV with a 1900Kv motor I can fly more than 30 minutes, and can climb 3m/seg... EXCELENT BATERY...
These batteries are great, I bought two of these and they were both severely underrated, they definitely held up against my 30c battery with the same voltage and amps, with one of these in my plane, I have calculated a possible half hour fly time, all for less than a 7.2v 100mah battery from my local hobby store!
