Protek 3600 vs 4900 for stock buggy racing
Anyone using the lighter 3600 model. It is 55 grams lighter. Been using 4500 orion but need a new battery for my new 22 4.0 buggy. Trying to keep the weight down but do not want to hurt for power. Mains run 7 minutes and sometimes 10 minutes.

I've had mixed results between running a sub shorty and standard shorty pack. The sub shorty is a cheap method to reduce weight to reach min class weight which will certainly improve acceleration to clear jumps easier as well as slightly faster corner speed, however I've had even better luck by reducing weight with lighter drive line parts to reduce as much rotating mass as possible, then I try to remove as much weight placed high such as minimizing wire length, mount the motor tabs as low as possible, lightened body, titanium hardware, etc then go with the standard shorty to bring the weight back up to spec and selecting the highest C rating and capacity (multiply them together to get relative amp draw = rA). Given 2 cars of equal weight, the pack with the higher rA will win out. Only drawback to running standard shorty at min class weight is that it can get pricey to reduce rotating mass with upgrades through MIP, etc...

It can be fine if you need to, but you'll have lower finish voltage compared to the 4900mah pack.
You will feel this at the 6 minute mark for sure if you're in tune with your car.

i think the higher avg voltage at the end of the run will out weigh the grams saving
