I am trying to hit higher and higher speeds on the street using an RC8.2E. Currently I have the RTR version with Tekin RX8, on 5s lipo, and I am moving to a 6S pack.

Since the voltage and amperage drop during a speed run, I thought about something. What if I added a small 2S pack in a place I have found it to fit, connected it by some type of relay, and when the vehicle reached top speed, I could use the 3rd channel on my M11 tx to activate the voltage in the boost pack, which would only be used for 2-4 speed runs as to not deplete the pack.

Is this possible to do? Say with a pair of large capacitors between the two voltage sources?

The goal here is for a nitrous/turbo effect on the car. The car doesn't need the weight of a big block engine (8S or [2x 4S]) pack weight, the main pack is still decently large, the small pack doesn't add much weight, and it dumps itself quickly in contribution to the top speed of the short run. I got the buggy cheap and track racing is not my thing yet, so I went the max speed route for fun.
