I was thinking more of having Ping assemble it as a 12v pack... He USED to do lots of custom stuff, and was reasonably priced and good quality. You now can get 12v 10Ah Dakoda Car Batteries for $99 with BMS's and everything built in so I was hoping to get something a bit bigger for similar...

Since I built the Sidekick, and was working on an Electric Geo I have moved several times, and gotten a bit older... Most of my Weekend projects have been donated to various schools, and that hurt a lot.... However, got ONE project left... Camping with toys and gadgets.... Have a 6x10' cargo...

Since 18V seems an "odd" voltage, can I just use TWO (2) 9.6v packs in series? That should make the packs standard, and the charger(s) as well... Should be cheaper as I have some 2-packs of 9.6v racing lipo packs CHEAP... Not sure what the Peak current output of a SubC NiCad is...but I am...

Looks good, a question or so... 5S makes sense 5A Charger Makes sense Why do I need a 12V Power Supply? Aha... Not charging Directly, have to go 120V>>12V>>Charger...Now it makes sense...sortof.... Might be a bit more of a kludge than I expected... I will look at that a bit more...

On something TOTALLY Different... My Cordless Chainsaw has eaten the third and Final 18V Pack I had.... I would like to take one of the Dead packs, put a short cord on it to a wearable pack... BUT... I haven't seen any 18V Packs or Chargers available, and don't really want to build one myself...

Well the Side Kick came out of winter storage, the NiMH pack was topped off, and away it went... So I can say that the NiMh pack stored well (off a charger) with no problems... It is from http://www.coloradoadvancedbattery.com/category-s/22.htm and it does exactly what they say it does... I...

After smoking several Crystallite controllers on my PVC-Quad, I tried a Kelly controller and it has survived and has done well. That was the SOLE reason for its inclusion in my final list. Both this board and the EVDL board are full of posts about Kelly's "cutting back" after prolonged use...

That is not a controller I have seen on the lists... I have seen it when I did my searches, but didn't see ANY in use in the 30 or so Geo Metro's that have been converted. It is an expensive controller, and liquid adds a bit more to the price... I also don't want to be Beta plus... The Zilla...

I have been getting closer and closer on my CAR project to where I needed to order a Big Controller... the 144V-650A size.... I had been waffling between Kelly, Zilla, Curtis, Synkromotive, logisystems and a few other Big controllers. Slowly I had eliminated the "Dumb" controllers as I wanted...

What I really want is a "Battery Top Clamp/Shunt" similar to the picture. OR.. A version that would bolt to ONE terminal and have a pigtail to the other to allow for varying size batteries. Each would link to it's brethren with a 4 pin cable and then to link to a "master" controller that gives...

Over of the EVDL list, which is more for Car and Truck type EV's, the chargers of choice are Zivan, Manzanita or Rusco. Depending on your source voltage they are capable of 60 or even 80 amps, so the 30A (.5C) needed for a 60Ahr pack would be easy. I am looking into a "hybrid" system using the...

I took a look at the "Assembly Instruction" which also included the latest schematic.... While the Shunt portion of the BMS looks like it would be fine for the final balancing portion of the charge, I don't think the FET, even with a HeatSink will be even close to handling the Full (bulk)...

Can you put several of these in Series to charge even larger Voltage packs? I am looking at a 40-Cell (120V) pack for an EV car... You also mentioned some mods for larger current packs, but I never saw a follow up on that item? (My target pack is a 120V (40 Cell) 150Ahr Blue Sky Pack)

I know the Potentiometer that Curtis uses in the ubiquitous PB-6 is an Odd one, like 170deg turn or something... Does someone know the specs so I can try to find a Hall-Effect replacement on mouser or DigiKey ??

I finally have a donor car and am starting the homework for converting to Electric. I would love to see some discussions on LARGE packs as I am looking in the realm of 120V and 100Ahrs... (With a 700lb lead pack this will give me about 20-25mi usable range, but limited cycles...) Prismatic...
