Thank you everyone, I appreciate the replies. The motor and controller are part of an overall kit from e-bikekit.com, it wasn't something I pieced together. I wouldn't be against upgrading the controller if that's what it took to fix the issue but customization would be venturing beyond my...

Hello everyone, I'm stumped as to the issue with my e-bike conversion. When I give it either near full-throttle or any throttle under load, it makes a loud resonant frequency-type hum across the entire bike chassis. I've reached out to the kit manufacturer and after some back-and-forth with...

Great workmanship, looks great! Random question: Does it have a lock on it? It's a little on the large side for my needs though, although the stealthy aspect is appealing. Will there be smaller ones made in the future? What a great design!

I had a similar poor experience with ebay batteries. I had read the "dangers" here going in to the purchase, but the super low price combined with the fact you can't find sub-10ah LiFePO4 batteries anywhere made me pull the trigger (it was a water bottle battery, 6ah). It is darn near...

Reading through this thread it sounds like the NiCoMn batteries themselves from BMSbattery are fine, but the BMS they use are subpar. So if one could install a different BMS, this pack wouldn't be such a bad deal at the lower prices & weight, correct?

Thanks guys, I'm realizing my confusion was really just about whether or not I needed a specific amperage rating out of a multimeter for these batteries. Now that I know I could use just about any multimeter, my question has been answered. :) FWIW- I already have a computer display for this...

Sorry, I should have clarified. I have LiFeO4 batteries. I'm looking for something I can use at home to test the batteries when they're off the bike as well, to monitor charge for storage, maintenance charge monitoring, etc...

Looking for an inexpensive unit to measure the batteries for my bikes (I just want something easy to pack for when I'm out on the road.) Guessing I need the basic voltage & amperage at a minimum, but how much amperage capability do I need? I noticed most of the cheaper multimeters don't seem to...

Thanks Dan, I had already sent an inquiry to cell_man and am just waiting for his response. :) I did hear back from Ping, actually, and he said he could assemble the pack in a week and that I would receive it in a week - but I'm skeptical since that contradicts what his website describes about...

Thanks, I appreciate the advice! I guess it doesn't have to be LiFePO4 per se, but I would prefer Lithium as I'm concerned about weight and battery maintenance/longevity. I tried contacting Grin yesterday but didn't get a response. I tried contacting FalconEV as well, no response (is it odd so...

Ha, don't I know it. Hindsight, 20/20, and all that... I would prefer a pack that can handle at least a continuous 2C load. Many of the nicer packs I've seen are closer to 4C-6C. I read the big merged thread in sale forum about the AllCells not being truly 2C and actually being 1C which only...

I appreciate the responses everyone. I'm in Seattle, WA (nothing in classifieds matches my needs though, unfortunately) - and I actually need two of these packs (for two bikes) so a single used pack wouldn't get me there. I forgot to say that I looked at cell_man too and I would order from him...

Hey guys, this is my first post so take it easy on me. :) I've spent weeks reading the forums and only just now registered. I have a situation where I need to have the batteries at my doorstep in two weeks (at most). Unfortunately this eliminates ordering from Ping or cell_man. I don't have a...
