Re: Assembled Hi-Power LiPo battery packs - any interest?

Am I to surmise that storing lipos at anything below 4.2 is fine? how goes the cycle tests so far? I've also read and tested (not at any great lengths yet) that if you compress lipos they work better as the partials are forced closer to each other

Re: Definitive Tests on the Heating and Cooling of Hub Motors

The green compound the copper is in cased in looks like it, would no doubt, be detrimental to the over all cooling process, claims of 6k continuous, has anyone got one of these can report findings?

Re: Definitive Tests on the Heating and Cooling of Hub Motors

has anyone done a system where you shoot water at your hub with a water pump, water on the hub is very effective at cooling the motor, I find that the hub motor with fins and ff work well with no Re Gen but as soon as that Re Gen kicks in the hub becomes a grill pan, although it does stop the motor ...

Yes one of these would be boss, now how do i get the money. Do you think they are going to be a better version of this somewhere down the line, because with 80-100 volts and a slightly wider frame for moto tyres this could replace dirt bikes?

Re: Advanced ADAPTTO controllers and compatible products

I think the problem with adaptto was with the mosfet number they only used 18, sabvoton uses 36 for the same power. mosfet number is related to the wave signal to the motor, it seems to me that the more mosfet you pack the higher the wave function (complexity of the wave, or purity of sine wave shap...
