A pack like Paul would build keeps all the dangerous and technical stuff hidden so all you have to do is ride.Īs I continue to get deeper into this stuff, the final requirements start to figure out. If you were to split the pack into multiple small packs for easy fitment on the bike, you increase the chances of someone getting hurt reconnecting wires if they get knocked loose. If your wife is going to be using the bike and she doesn't want to understand all of the technical stuff about the batteries, that's even more reason to use a safe pack with a BMS and simple charger. By the time you get through all the hassle of using them you could have just gotten an idiot proof pack from somewhere that is as easy to charge as a cell phone. You end up needing monitoring devices and a balance charger as well as parallel connection wiring. They also can require a confusing mess of wires to connect. When you figure out what voltage and capacity you want it wouldn't hurt to send them an email.Ĭheap lipo packs are tempting but they can be dangerous. If you wanted a really strange shape and didn't care about a warranty I think he would still do it. Without a BMS he wouldn't warranty the pack.

The only stipulation on the custom pack was that it needs to be wide enough to incorporate the BMS. There is a small upcharge for the custom configuration but still very reasonable. Im not sure there is a link to custom pack building but I have emailed paul within the last year about a custom 72v pack and he got back to me with pricing. I'm sure I will have a ton of questions to come, just please, help me to start. Which vendor? I heard a lot of good things about em3ev, does his reputation worth the additional price? Which battery to take, so it will be compact and strong?ģ. Which option is the best, with the reliability at first?Ģ. I need the motor for singles and sometimes steep ups. 350W/500W/750W? I am 170-180 lbs fully geared and still loosing.

No to the first step questions, I can't figure out by myself, since I don't have a slightest idea:ġ. So I need to attach the battery to the downtube, but this limits me to compact, and thus powerful cells. I can't have the battery on a rack, since it will just fall off. Now to the problems - the frame I try to couple with BBS02 is an Ibis frame, which means there's almost no straight lines. After a lot of inquiry I found the motor that will suit me, my riding environment and riding style the best. I need to electrify my Mojo, and seeking for the community help, since I'm a complete noob in this whole e-biking.
