It's not that type. The lock assembly is outside the case; the pin is not accessible and it is fastened to the case from inside; it has to be unlocked to be able to non-destructively modify it.

I have a Populo Lift V2 that I just got secondhand. I like it pretty well, though it's a bit of a slug. It didn't come with a key for the battery lock. The key isn't needed to power the bike, just to remove the battery. I've looked for replacement keys online to no avail; Populo is apparently a...

Can you expand on how you balance the pack manually? Extremely interested. Thank you.

Hey thank you sir, extremely helpful. I shall read up and (maybe) try it.

By range test I mean ride it into the dirt on the full charge that it has, then be able to charge it back up some so that it would be usable again while I wait for the other charger. But if I understand you correctly, I can charge individual cells in my pack even while they're connected to the...

So I finally finished assembling my 13S3P SPIM08 battery pack monstrosity. This is a straight-up experimental build and I suspect I'm going to have reconnect everything after a test ride or three. Unfortunately the 48v charger I bought with the rest of the bucket of parts was DOA. So I have a...

I'm in the experimenting-and-making-lots-of-sparks portion of the process personally. I've aborted two builds thus far; I'm just noodling around TBH. I've never built a battery before. These things are kind of a pain in the ass to work with, I'll say that. Four g-d surfaces to guard against...

FYI you can turn balance charging off for LiIo.

Ah, similar to the way we test bridge maximum loads today - drive heavier and heavier trucks across it until it collapses. Then rebuild the bridge and put up a sign saying the max load is a little bit less than that truck's weight.

You might be jumping the gun. I recall reading another builder writing about these cells and how they stuck at 3.6v for a loooong time under load, i.e., that's where most of their juice is. They might not be high-performance but in adequate numbers I gather that they keep the voltage up and have...

Thanks for the info, I will.

Right, but it's 6A at 120 volts (720w); these are for fluorescent lights. My max load is 20A at 36 volts - same wattage. Or is that not how it works?

I'm working on my bike today and needing a resilient reusable connector (bike is stored outdoors, <30 climate, have to charge battery indoors), so I was about to order some XT60s when I decided to check Home Depot (there's one across the street, so it's quicker than Amazon) and I saw these...

OK, so all three negative wires all just glommed together? And that doesn't create a connection during the charge cycle? I really don't want to blow anything up. Hmm, so two toggles would be basically the same thing as wiring them parallel, right? The output from each toggle would go into one...
