Darn...no over-volting the Monster

personaly all i need it to do is 16nimh. then maybe some of those li-ion sony cells. in a 5-6s2p config

A 6s is 25.2 volts fully charged so that only allows .8 of a volt before melt down.

I think its disrespect to castle to call it such a disappointment.

You're right.

Castle dudes, I'm sorry I disrespected you...

[Joe Ford]

LOL...all good man. Just don't do it again.

7s A123 is max, 6s lipo max. You guys can do a LOT with 6s.

I personally think the TVS is a great idea! It keeps high voltage spikes from getting to the battery during heavy braking, which can't be good for lipos.

Didn't GriffinRU do that on hid modded MM?

[BrianG]

Dunno, I don't remember him doing that. I do know the topic has been raised before...

[lutach]

Just found it. He did do it.

So Joe, I'm gonna ask the same damn question again:

Are you planning on releasing a HV version of the Mamba Monster?

Patrick said an 8S version would need just a few changes done to the components, but a 12S version will be gladly excepted. I'm done asking. So you guys feel free to ask for one.

[captain harlock]

Just get us a 8s version out and this world will be a better place for us, Castle.

Anything between 8s and 12s would be good. Seems like using higher voltage on the cheaper feigao motors works better and produces less heat.

But the MMM will be very welcome, I am looking forward to it!

Believe me, I am looking at doing an 8S or 12S version (or both) of the MMM --

My question is:

Would people be willing to spend an extre $120.00 on a 12S MMM? That's really the minimum extra it would cost to do a 12S controller...

Also, a 12S system would more than likely be Opto, to keep the motor noise from the radio. So would require an external power source for the RX/Servos.

An 8S system would certainly be easier, but still a little more costly than the 6S system.

I guess the extra $120 will be because of the controller being completely different from the 6S right? I can work with Opto as most of my HV controlelrs are Opto. I'm in for 4 maybe more 12S units as I can use 8S and 6S as well with it.

Off topic: Can a simple forward/brake software be made for the SHV if the hardware is not compatible with the Mamba software?

The difference in cost is because of the difference in number and price of the MOSFETs. Double FETs with higher price for a 12S system. Remember, MOSFET resistance goes up by the square of the voltage.

There probably won't be any forward/reverse SHV software made available. It just doesn't have the hardware for braking/starting heavy loads.

BTW, I'm in China now, checking progress on the Neu/Castle motor assembly line design. Pretty close to building motors. If I get a chance, I'll post some pics.
