I havent looked but these connectors are stocked in a lot of places. They are made in China so Im buying them from Taobao to save some $

What is this sf1612-21 one for? Sensors?
I probably wrote the code wrong, but I think I got it, sf1612 series, 2 pin count, with solder connectors

Oh that’s a cool idea too. I feel like it could do with a much smaller connector though considering how little current goes through the sensor wires

Yeah trying to find something sensible
The hole size isnt an issue. Its the massive aluminium part
This looks like the one that haggy is using, kinda tempted to get a few but not sure what the price is

they look kinda like gx16 connectors
but the other way around
I have the GX-16-2 on one of my boards and it’s great. Just ordered some of the rubber dust connectors for it though

i ordered metal screw on caps
I like the simplicity and size of DC5521 but it does get a bit hot @ 4A, got some gx12-2 as well but the current capability is pretty much the same so havent bothered to switch them out.
The ones I linked above are a no go for charging but would be nice for sensor wires
Do they come in 6 pin size tiny as well?
The metal ones are real nice 
I guess this is for charging and not sensors?
Theres
SF8 series - 8mm diameter
SF12 series - 12mm diameter
use SF12 - charging
Not sure how much amps go through those sensor wires…
So, I had to repair one pack for electric bike. 4-5 years old. As you can see, pack is profesionally built in factory. Due to age (or whatever reason) one cell went poof and killed whole group. There is space and plastic between cells and gap on nickel so cell could vent. My question is - what can we, battery builders, expect from our packs after few years? We rarely use spacers, which means if one cell goes poof, whole group will get chain reaction and go poof, in best case. In worst case, whole pack could be part of chain reaction and possibly catch fire.
What is your opinion? Are we building packs safe enough (poof-proof)? Is there something we can do about it, except using spacers or giving notice of limited cycle life?

Miniscule amounts compared to charging

I’ve started using spacers in my recent packs and the experience overall is much nicer plus the packs looks cleaner and feel stronger
But I don’t thing it’s enough, with the way we abuse packs they have a very limited life cycle to begin with so if anything happens they would all be in poor condition to far more prone to fire (as the chemistry degrades, so does the capacity and stability…cells that have a noticable decrease in range or current support will burn up easier anyway)
I think packs should be retired after several hundred cycles or a couple years (which ever is FIRST)

Yeah i had words with him and he blocked me and deleted the posts. @Psychotiller if there was nothing wrong with that battery, why take the posts down?

gosh i remember when i first got into this whole thing i almost bought a tiller battery but they were all out of stock on his website. He seemed to have a good rep then–I know the flexl and undelivered enclosures fucked that up but i didnt know it’s his batteries too.
