I run 4s 6500 packs from MaxAmps, 15 to 20 min run time depending on the size of the track.
3yr warranty and excellent punch and power.

I run a Turnigy 4s 30c 4500 hardcase for our 10 min Ebuggy mains. For 15 min mains I run a heavier Turnigy 5800 4s 25c battery in my Xray 809.

+1...the mah is up to you but the 1900kv runs best on 4s.

If you can go to 5s and gear the 1900kv down, do that. 1900 does run good on 4s, but a 5s would be better. 25C batteries heat up a bit, 30-40c would be best.

The Turnigy/Flightmax 40c-50c are pretty good. You can get them in 5000mah. I run 10 min easily, 15 could be done with the proper gearing/setup.

The 1900 wasn't designed to run on 5s. Stick with 4s. Like the guys said the mah will only affect your runtimes. More is mah is more runtime, less mah is less runtime.

Also make sure to get at least 30c continous discharge.

So what is the max RPM to run the T8's at? I can't believe 35000 is too much for these beasts. My 1900 on 4s draws a ton of juice, but watching a 5s 1700 setup runs much more efficient, but it's lacking a little speed.

I use a 5000Mah setup, because i busted my 5800mah one from not knowing about the velcro on the bottom of the battery.

I might upgrade to the 6500mah one in the future, but the 5000mah seems to give me optimum performance for the lower weight of the battery and smaller size. discharge is 35c and I only use 4s's.

BTW, I have a Tekin RX8/1900kv setup.

Im a n00b at this sport so PLEASE take my advice with a grain of salt as I am not the most credible.

Yes 4 cell is what you need. 4000-5000mah is good for most races 30-40c. Most get 230-250mah/minute so do your math to see what you need. the closer to 4000mah pack you get the more balanced you'll be on your chassis (granted your not running saddle pack set up)

Some of you running 4500mah for 10min and 5800 for 15min are getting terrible milage.

I use 3000mah in 15min on a grippy track, 4500 will dump just after 12 on a slick, dusty track.

Track size, shape, and condition can change your fuel requirements alot.

Turnigy is okay. IMO the best battery for the money is the Hyperion G3 5000mah. Killer punch, double the cycles of other lipos. That adds a ton of value right there. The price is right too.
