Re: Building battery from MAKITA Konion PACK

I would make all “P” groups the same voltage which would be most important. Then you want your “S” groups to be the same as well or as close as you can. If not the higher resistance “P” groups (lower voltage) will drag the rest of the pack down and if you use those in the middle of the pack could ov...

Re: 20s15p Sony Konion pack for sale

If you absorb the cost. I have a few looking so I think I’m going to replace the bad cells. That way it’s ready to go for whomever buys it.

Re: Building battery from MAKITA Konion PACK

Put them in groups......all cells that kept voltage at full charge 4.2 volts in one group. All cells that fell to 4.0 to 4.1v in another and so on.

Hopefully you end up with enough 4.2 cells to build your pack.

20s15p Sony Konion pack for sale

So I built this a couple years ago. Works great but I just built a 45amp 30Q pack and don’t need a second for back up. The good, I bought a bunch of Makita 18 volt packs from Doctorbass and pulled them apart. I went though all the cells, pulled the good and pitched the bad. Built using .2mm nickel a...

Re: Electroplating copper with pure nickel (PICS)

I have a fairly powerful capacitor discharge welder at 800 watt seconds (according to the designer can peak at 10,000 amps!) and can tell you that both copper and brass are very hard to weld. I’ve tried copper, glidcop and tungsten electrodes with almost no difference. I have read that a couple have...

Re: QS 205 experts needed

Lights, horn and accessories are better powered by a DC/DC converter. Vicor is the best. Or, there are now available some lights/horn kits that are ´universal’, up to 85c DC. Mopeds are usually not so good at handling the full power of a QS205h50. Let’s say, many would need some upgrades, suspensio...

Oh forgot to say there are many ways to get a charger that will work for you either pre built or gang up server power supplies to get to the voltage you need.

Re: Lets play build a battery.

All a big guess on what you actually might do and since your not for sure here goes, My figures should be pretty good in a hypothetical draft! :D Id tell you to stick with 24s which is 88 volts nominal and 100 volts hot off the charger. Since your looking at a 20kw motor we need to see your max amp ...

Re: BMW i3 Batteries

Ok, so 40HP = about 30KW. So if I use two of these BMW modules in series it will be 24S & at 250A continuous that’s roughly 22KW. 500A bursts would be roughly 44KW. I don’t think I could realistically match the performance of the tuned FL400 you had but stock should be doable. What about weight? An...

Re: Suzuki GSX-R e899 K2

Agreed....looks like something was bouncing around in there causing havoc. Wonder what that could have been? Since the magnetic ring is OK it might just be easier to order a new stator to your specs?
