I believe I have arrived at a conclusion. Hopefully this will help someone if they stumble across I have one of those cheap chinese BMS, less than 20 bucks. I have not ridden my bike regularly and I believe one of my parallel groups(PG) had fallen out of balance. I noticed PG 1-3 was at 3.9V...

Agreed. When it cuts, the display goes dark.

I have a battery welder. welded like the 6 side of a dice (die?).

I did some high speed runs with the battery off the ground and not supporting my weight. I don't think it drew enough current. I took my battery apart and checked the groups at the BMS lead connector: Grouping Series Voltage Parallel Voltage 1 3.9 3.9 2 7.8...

No regen, I'd love to have that someday.

I'll crack it open soon. Honestly, I'd love to buy a new controller because I want regen. I'm blowing through brake pads. Unfortunately, I think it's the battery. I'll post below.

Hello, I've got one of those 1500w Voilamart kits, a home made 58.8V 23AH battery with BMS. I've ridden this bike around 1K miles and recently started exhibiting this odd behavior. I'm getting a complete system shutdown (have to disconnect the battery from the BMS) in order to get power back...

Thanks for the reply, the frame is aluminum. I'm not sure about the photos, maybe they are still processing.

Hello, thanks for your help! I have an Ecoquip Euro 2900 ebike that I bought used on Craigslist, It has a 300w geared rear hub that I am swapping out for this hub. EDIT: Forgot to mention the original wheel is a 29", the new wheel is a 26" (shouldn't matter, but maybe it does?!) The original...

Dude thanks for the reply! I was getting discouraged that I could not get this answer. I actually have 6 gauge cable from a DIY welder I made but had poor results. Relay was sticking, really scary. I'll order tonight. I hope you get comission :P :bigthumb:

Hello, I know many people here seem to like malectrics's spot welder. I'll likely buy it, but I'm cautious of the import/customs process. Are there any United States owners on here who can share their buying experience? Did you have to deal with customs? Also, if you are a in the market to...
