I have the battery shown below. But I need a replacement connector (the male connector, shown circled in orange). Anyone know where I can get this connector? Any help is appreciated.

The Sec 1.15 exemption seems pretty clear - perhaps your friend happened on a dimwit of a customs guy; it might help to print out Sec 1.15 to show them. https://www.tc.gc.ca/eng/tdg/clear-part1-475.htm#sec115 Paraphrasing of Sec 1.15 (Nullius in verba) : Sec 1.15 (1): Part 3 (Documentation)...

Hi MadRhino... are you sure you need a license? Transportation of Dangerous Goods Regulations 1.15 exempts a "user or purchaser" from all the nonsense: https://www.tc.gc.ca/eng/tdg/clear-part1-475.htm#sec115

I would like to point out: IMO, there is little risk of plugging the regular IEC connector into the IEC connector with the 90° ground blade. I tried this myself, and even a strong meathead would have trouble getting them to mate. For me, it would've required a hammer.

I'm having a problem with the TDCM sensor not being able to measure anything above "moderate" human watts. I'm using a TDCM sensor with CA v3. Chainring = 42T When observing the TRQ setup screen on CA: Pedal loading @ 0lb: 2.54v Pedal loading @ 50lb: 3.78v Pedal loading @ 100lb: 3.78v Pedal...

As the other guys have pointed out, yes I understand that the cells must be contained enough to prevent tab wiggling and corner crushing and the like. That's a given. But I'm talking about 100 pounds kind of force, or more. Perhaps much more. Somewhere I saw a picture of a guy sandwiching a...

Are you saying that expanding cells are a normal part of cell aging?

I have a couple of Lifepo4 pouch packs. A pouch has next to no structural integrity to it. Prismatic cells, OTOH, usually have a more rigid (sometimes aluminum?) enclosure. Same goes extra for cylindricals, whose round geometry can withstand substantial internal pressure. My cheap chinese...

Shuffling between 1 and 15 sense wires (depending on where the offending cell happens to be) sound likes alot of work too. And what do you do with the 16th now-unused (cuz there's now only 15 cells) sense wire?

Please explain if you can.

It's always that last hill...

I believe the BMS' overcurrent cutoff is 40A. And my max controller draw is 35A, not 40. The BMS cuts out just fine. If the fets were stuck-on, then the BMS wouldn't cut out. From what's been said so far, I'm fairly sure I know how a BMS works better than anyone who's so far replied to this...

15 amps? Where's the fun in that? That'd be less than half the power I'm used to. Anyhoo, fun as it may be, you are right in that 35A is probably rough on a 10Ahr pack. Although, the 35A is not continuous... as long as you consider less than 10 seconds at 35A not continuous...

One of the functions of a BMS is to monitor EACH cell voltage, and shut off the charging fets when ANY cell exceeds the max voltage (3.75v or whatever). So yes, my charger is 60V max, but no, no cell should ever reach 4V, cuz the charge current'll cut out as soon as any cell hits 3.75. That's...

I figure the existing 16s charger will work fine with 15s - the BMS will cut out and prevent any overcharging. This, of course, requires the BMS to be present.
