Gotcha. Yeah, the stock motors are rated for 9 volts, so pumping 11.1 volts from a 3S isn't a huge increase. It's just a couple volts. Literally, like 2.1 volts. From a performance-boost standpoint it's very similar to putting IMRs in a 6 volt blaster. Both of those upgrades provide a 23% increase in power/range/FPS. Weird coincidence ... right ? Not really.

I don't think you're getting the whole "current/voltage" thing. It doesn't matter how many amps the battery can supply, it's all about how many amps the motors want to draw. Here's a real-life example. I'm sure you know you can plug a night-light into a wall socket. It barely glows at night, right. Well, you can also plug a chainsaw, or a leaf blower, or a microwave oven into that same socket, right. And they work fine too !

That's because a typical household electrical socket provides about 15 to 20 amps of power. But different devices plugged into that socket will draw different amounts of current. Night-lights will draw a few milliamps (aka thousandths of an amp), whereas leaf blowers and shop vacs will draw 13 to 14 amps.

So why doesn't all that current in the wall socket blow the night-light right out of the wall ??? Heck, with all that power it should blow it up and catch fire, right ??? That's because it's not about how much power the socket supplies, it's about how much the device draws (aka requires).

And it's the same with LiPo batteries. I don't know if the lightbulb went off already, or you've done the math. But that 3S LiPo isn't giving you a great performance boost. Yes, it's an improvement, but a really small one, and for completely different reasons. And unfortunately that 21 amp switch was unnecessary. Cool, but totally unnecessary  🤘 If you're interested why, let me know. I'll be glad to explain it to everyone.
