Seconded on the MUHAHAHA and what's a bms more MUHAHAHA.
Oh and were the heck dyou get a 6" copper nail from
Heh you don't need a 6" nail, the shunts are only about 15mm long.
Thanks for the info Gangster and supplying these fab motors.
Oh crap got to take that frockin case of again :?
Just don't break it because this goose has laid the last of those golden eggs
The hulking 5404 can probably take 100 amps for a while and the H40 can too but not as much. I have had the one on my fighter pretty warm when thrashing but then I am feeding it with double the power.
You may not need to remove the board from the case. Remove the end plate with the switch on it and shunts maybe be visible and accessable just there. I know they are on the 12 fets and some of the 18 fets but my particular one is different.
There's a few methods for shunt modding:
* blob on a bit of solder (which I wouldn't recommend)
* solder in a few strands of wire in parallel with the existing shunts (what I often do)
* wrap a bit of copper wire around the 2 shunts up to 1/3rd or 1/2 their length (or what ever) and then solder over it. That will increase the current by the factor that wrap the shunts together (eg if you half wrap it the current will double) I'd start with just 1/3rd, that will give you a decent boost in power that's still safe for the motor and controller.
If you dont get what I mean by wrapping the wire around the 2 shunts - imagine the shunts are your 2 legs and you're bandaging them together. Start and the ankles and strap the 2 legs together until you reach the knees
