Hi Tony glad to hear from you. I always value your input. Thanks for your insight and for the resource info. I have not used them as a vendor.
Take care of yourself!
Hey Rick, I’m still here. Busy but I still come to look at the pictures. And boy do you post some nice ones. After logging around 6000 miles and three hard accidents including one dead deer, I blew up my bike. I had just begun the inspection tear down that morning, when my friends said they’re out on a ride and to meet them up in the mountains. At about 50mph one of the corner cells blew up, blowing half the pack out the bike, slightly bruising my leg. The pack and onboard charger were like guts, just hanging out the side swinging on the battery cables. That half of the cells got road rashed and caught fire about an hour later.. in the back of somebody’s truck. Fortunately the truck did not get scrapped but I had to replace his bed liner. I shoulda known not to use polyester resin in my bodywork as it is very flammable. My side cover completely burned back into pure cloth form. At some point something else caught fire and burned the other side, completely melting my throttle, headlight, and burning some more of the flammable bodywork. Not knowing the cause of the problem I immediately recalled all packs I built with that type of cell. Fortunately I didn’t sell many as the cells were hard to find, so I only recalled one pack and offered replacement options to other customers who ultimately decided to keep them. Later research and inspection led me to conclude the battery had gotten damaged in the prior accidents. Since it was a pain to access it I did not inspect it each time.
I’ve been using pouches from other manufacturers with no issue. I just picked up some 75ah cells that boast super rates including a rated charge in 20 minutes; but it would require some more hardware. For now I’m setup for 72v 90 amps charging or 80% in about 40 minutes. This might just be fast enough. The 48ah packs I’ve been selling, I’ve charged at 40-45 amps and they take it will a little heating. Even that is enough, at this point the experience has less to do with charging speed and more to do with vehicle comfort and riding habits, ie how fast the battery is spent and how often you take a break.
