A friend of mine is trying to convince me that his lead-acids have a "memory" and need to be periodically discharged completely. Any thoughts?

motor temp

My D&D motor has a thermocouple imbedded in one of the brushes. This responds quickly altho it gives alarmingly high readings. The Advanced DC motor which I just bought for another project offers no such option so I'm thinking that the simplest way is to mount a thermocouple in the cooling air e...

Re: connectors

night train I guess I won't try it to see; I had hoped that someone already had. After my controller exploded (literally) I thought it a good idea to add an emergency disconnect so I installed an Anderson. I wonder now if that's the proper solution. In an emergency situation one might be breaking fu...

reverse
