So some of the progress i have made in some time...

Well after some time, I finally got the dam thing mostly usable. The 38120 headway cells did not go over so well..... so RC Lipo it is. 2 series 4 parallel. Within the pack. There are 12 cells in total, half of which are in series. The other half are in parallel total pack voltage 100.8@ 20Ah. I...

Slowco thanks for the comment! It means a lot! And you hit the nail on the proverbial head!! The cell's are space far apart for air cooling and also, space and for a rubber retaining ring to keep them isolated from the aluminum sheets that hold them together. I set the seat that far back for a...

Not to much to say. But some more progress!!!

Noted, thanks for the idea

so when, and if the charger that i have built fails open there's not that much crisis. If it feels closed it goes straight to Mains for .04 sec ( tested )and the 15 amp breaker will trip immediately. I am not saying that the charger that I have made is safe in any way, nor have I suggested for...

Thanks for the tips.

flippy. The base current is set buy the pot only the side of the case and that is independent of voltage to a point. But i am sure you know all about this as this is Elementary level power control. Let me ask you what happens when any powersupply fails. S#÷t goes awry as I am sure you are...

Punx0r Indeed !

Flat tire the type of pot that I have utilized is lockable. And the only pot is for establishing base/max current the 5740TV takes care of the rest. This is not cc/cv this is a cv charger I set the charge currant the 5740TV takes the pack off line when the cells all reach 3.5 volts my last pack...

I am not sure of that without more information on your set up.... all I can say is that what I have used works for me....but I am sure it depends on the current voltage level that you are trying to achieve

Sorry john61ct I will stop. I was just trying to show how I made my charger that's all

You have made many assumptions. And that's OK we all do it. Also Google JLD5740TV. Once again you assume someone would plug battery pack directly into a wall... you assumed the term Universal motor is the type that some needs frequency control. You know the type of motor with electromagnets...

I'm not sure who's more confused you or me. I to dabble in the world of power electronic design. switch mode topologies is my specialty. Just wanted to offer a bit of cheap knowledge for anyone willing to build inexpensive extremely dangerous charger that works well.
