Dual 9volt works but not 18 volts.

LOL. dude, you're cracking me up.


I will give you that two cells @ 10C ratings with different mAh ratings, the higher mAh rated battery will outperform the lower one.

It really is simple math. C rating is a reference. 1C is commonly called "one hour discharge". 2C is .5 hour discharge. 10C would be 1/10 hour discharge. a 750mAh cell with a 10C rating will STOMP a 1000mAh cell with a 2C rating. And trust me, 1000mAh cells with 2C ratings do exist, and people do try to use them. These are commonly called "low dischage" cells and are more suited for use in low draw devices for extended runtimes.


Blah blah blah. Is right. So far i've seen you post nothing to back up any of your statements.

Ok, you win. Let's be friends.

Actually, not tru. Being the mad scientist (and alot of pressure from the local RS) we were curious how much voltage the new ones could handle. So i had a single AAA holder, a double AAA holder and a few of the quad AAA holders. Started out with the stock 4 (Yes we kept the batterys fully charged) added 1, tested, 2, etc etc etc. We were able to get up to 16 AAA batterys (19.2v) and the only thing that fried was the motors (Went through 3 of em). We sheared the dogbones, && stripped the rear end. I was surprized that the servo didn't fry with how spaztistic the front tires were. U might b saying to yourself, "so you got a good board", this is what i thought, so i tried it on the H2, and the Firebird, the firebird didn't want to turn on past 12 cells, but the h2 turned on, and blew the rear end first time i got on it. I might have been lucky, i don't reccommend on jumping from 4 cell to a 12 cell, step up gradually. We also tried the dual 9v bat. We came the the conclusion that a 6 cell (rechargable) could beat a 9v (Alk). We didn't try rechargables, just regular Alkaline 9v's.

He was referring to a gen 1 xmod, which will blow at that high of voltage.

its basically impossible to burn out the stock motor i ran 36volts which was super duper fast on only the motor and it was fine but it seemed to be some what back firing 4 9 volts wouldve tried more but couldnt find anymore 9 volts but it might be slower than what i had mine runnin it was the stock motor no mods and i was runnin super low resistance cause i was using a single copper for every connection in the circuit

First of all, there are a few things wrong with this whole situation. Voltage only makes the motors go faster if you can supply the current it draws at that voltage. 9V batteries are not able to dump the amount of current needed because they're composed of 6 tiny cells. Also, with small copper wires, you're also limiting the current to the motor. Try 10 Li-po cells hooked in series if you're that confident. The armature wire inside will instantly melt.

The only reason your motor ran was because the current was restricted.
