    If it was just between those two choices, 21S5P (77V 25AH)

    This is a pretty good video comparing the performance of different popular cells. The 50S I used did pretty well.

    They don't really compare directly. The biggest difference is the BGX is a lot more socially acceptable on group rides. My Stealth has exceptional speed and range. I ride them differently.

    Anything on 2 wheels is dangerous, doesn't matter how fast it is. Where I live you'll get mowed down from behind on your "legal" bike just as quick by some dumb ass that followed your advise, and got a car instead of a bike.

    Question for the brain trust, is it possible to program the DC3 computer on B52 for Li-ion battery instead of Lifepo4 ?

    I forgot to thank docw009 for explaining how to order the right size shrink wrap. Thank you, it fit perfectly.

    Stealth reminds me a lot of Harley. Harley had 2 great ideas, Sportsters, and Big Twins. Every other bike they've tried to sell that wasn't a Sportster or Big Twin ended in failure. Stealth has 2 great models too. Bombers, and Fighters. Harley tried unsuccessfully to establish a line of small...

    Welcome, and I hope you love your bike as much as I love mine. We have to stick together because there's not many of us.

    I was able to use plastic cell holders, which cut down on a lot of extra work. The copper composite strips were a revelation. Without them it would have been almost impossible to build a good battery that can handle this much current with only 7p. In order to get it to fit I had to build the...

    I just finished building my first battery pack for my Bomber. I tried to find an adequate replacement for over a year for my third worn out battery, but no one wanted to build one like I wanted, and Stealth aftermarket is nonexistent. Now after building it I can understand why, it's a tough one...

    After 50 miles of testing this is the report. It runs like stink. Off the line feels about the same, but 25 to 30 it's looking for an excuse to pull the wheel up. I cruised over 50 mph and it wasn't even full throttle, and still only 4v sag. I think I can conservatively say it now has 10%...

    Your first guess is right. I thought it was a fuse. It's a fancy butt connector. The little wire is a power takeoff for something like maybe a sensor. These connectors are how the line power wires are connected to the bms, and output cables.

    Nope, it's not a temperature sensor.

    Mr EEs background is military and defense. He added this to my battery. Anybody know what this is?

    I guess I need to make 72v 35ah battery pack

    Success after the last post I did a little more insulating, and srunk the shrink wrap, and called it good. So far I've ridden a 7 mile test ride, and it feels really good. I did a few 80% throttle bursts, and I only saw 4v sag. That's a lot better than before. When I got back I removed the...

    At long last my battery is almost finished. I think today's the day. All it lacks is the output plug, and the shrink wrap. I already charged it to 83.4v. That's what it's set for. It took me a while to figure out how to open the ANT app, but it works now. I think this is looking like a good...

    Are you sure about that?, My chargers are 84v. This bms is set to stop charging at 4.17v, so it considers 83.4v a full charge. What's wrong with that?

    I finally got this bastard to come alive. I didn't know I was going to have to program the bms before it would work. I think I'll need some help going over some of the settings I don't understand. It took me about 3 hours to figure out how to connect to the ANT bms app. I also figured out you...

    Got a lot done in the last 2 weeks. The bms is installed. Next I'm going to run the output cables. Finish with a little more insulating, and then shrink wrap the whole thing. Should be finished with the build by Saturday.

    We soldered all the wires to the bms. Next I'm going to do some insulating, and then solder the main buss wires.
