I'm wondering the same thing. I have the rtr battery and it runs out quick in my barrage. I have a dynamite 7.4V 180mAh 20C 2S LiPo (same connector) sitting around and I'm wondering if it's not a good idea to use for some reason?? I put it in for a few minutes to see if anything drastic would happen and it seemed ok - definitely has a little more get up and go.

I'm new to a lot fo the tech stuff in this hobby so any help is appreciated.

Just a quick followup - I figured I might as well ask Horizon about this. THey said that yes I can use that Lipo, but to be careful not to drain it too low since the esc doesn't have a cutoff.

2s lipo is fine, but as said the electronics don't have a LVC so you may want a cheap Lipo alarm. Another problem is lipo has more voltage and definitely more punch from a dead stop. It makes the lack of gear reduction much more obvious.

The next step after volting up is of course gearing down. The Version 2 (V2) transmission from the RC4WD is pretty popular and with custom brackets and some work on the driveshaft outputs it will bolt up for about $25-30

Another option is the CR-24 transmission, especially with the stock spur gear from a Barrage which is much bigger, and a 9t pinion. If you order the transmission case, gears, shafts, bushings, skid plate,and motor (slightly different mounting) it should cost you the same or less than RC4WD and be completely bolt in.

If you want the smoothest slowest low speed control above that it's time for a better ESC and radio. The XYS-BL20A is pretty good for the money (less than $10)
However the best is going to be a Castle Creations micro ESC or a Tekin B1R, both are smooth with adjustable throttle curves.

As far as batteries with the proper connector, they are out there, but cost a bit more. IMO it's a perfect excuse for a cheap soldering iron or soldering station. It's a very useful tool in the RC Hobby and around the house or any other electronics.
