Ok a while back I thought this server said some upp was alright, did something change?
I haven't followed the entire rossman battery fire thing is that what did it?
We discovered that their build quality is actually terrible
and they're deceptive about it
not quite clear if they got crappier over time, or if some of the deception/issues were always there
I don't think I've seen any evidence yet that they lie about their cells - at least for the packs for which they specify a name-brand cell. I'm interested if there are any solid reports of that @heroi
But yeah, no cell-level fusing, and nickel-*coated* steel bus bars just to add insult to injury. A few people have also verified that they were lied to about their BMS specs.
As @Orange_C mentioned, not clear if they've always been this bad, but it seems like they've been like this for a few years now at least. IMO they're absolutely no better than any random no-name eBay/Amazon seller we'd normally advise against, at this point.
And yeah @ethan_stark, the Rossmann battery fire was the point where we really started to question UPP - there is no clear reason, if that battery was built to the claimed spec, for it to have gone up how and when it did.
But since the Rossmann fire, more and more evidence of UPP's shittiness in the last few years (at least) has come to our attention, making it clear that Rossmann's experience wasn't a one-off.
^^^^^
Id be more OK with a vendor that at least delivered the crap they promised, then one that promised the moon and delivered crap.
it costs nothing, except some potential sales to *not* advertise lies.
letting people spec how shitty their battery is would be nice too.
like ok, nickel plated copper and welding costs and extra $30 a battery... so uh, add that as an upcharge to the listing? everyone likes that battery that starts at $15 even if it ends up being $399 once you add the features needed to make it not explode.
It is fused, just at a few hundred amps per cell
remember, pennies are 100A fuse replacement
and nickels? they are good for 500A.
Copper or zinc penny?
Can confirm a standard wall plate steel screw is a at least 220v 30a fuse
1500f fuse at that XD
The laughing cow cheese
Oddly specific
Indeed
as a bonus you get cooked cheese
That....might be why the hall sensors aren’t working
looks toasty?
Ouch

Turns out what happened to this battery is one of the balancing resistor groups fried and then that parallel group went to 0.7v. Luckily it’s on the end of the pack. I’m just gonna convert it to 36v or something (remove a few groups of cells), buy a BMS, and use it for 36v stuff or other applicable appliances / vehicles :D
I have 36v stuff that have no batteries
@Rotated did you confirm if the battery fits
:thonk:
I have a razor mx650 with no batts. It uses 3 12AH SLA’s in series. This tiny thing will fit :)
And i have some other things on which it might fit maybe.
Most likely because they are all made for SLA
lol!
i was asking about your DM
:thonk:
I knew it was fixable to some extent
Ohh that
Hahaha uhhh
Barely
I am thinking I may have to fold the thing
Then I can fit it in the frame
If I put it on a rear rack I’ll have a 90 10 weight ratio
lol
👀
I mean whatever you want to do
I'll probably have to actually box it up and take it to fedex to get a shipping estimate
👀
The other option is modifying my frame (my dad is the man for that he has a welder extra metal and a ton of experience) and I don’t want to do that
Yeah
because they aren't exactly giving hazmat shipping estimates on the site
from what I'm seeing
I still want it even if i cannot modify it to fit in my bike because there’s other things I can use it for
Fair enough :o
What's the backup plan if the fedex shit doesn't go through for whatever reason
:o
Driving to you
haha
wherefrom again
Sidney NY
👀
so Upstate
Damn
That's quite upstate
I don't think I've ever been to that area before
at that rate it makes me wish I could afford to buy more of your stuff because it would be worth the trip üò≠
It's annoyingly far from schenectady and albany even
not really close to ithaca, utica, or syracuse
:|
damn
Yeah
you're shafted, rotated
that's gotta be one of the most annoying places
when are you moving out
When I move out I won’t be going to a city
I don’t wanna be in a big city
Why not

preeaachh
oi
nah I like the peace of the country
against cities
stop telling him to preach
:thonk:
forest cabin
he proselytizes enough
rotated, i was on the fence about adding per cell fuses in my battery and you convinced me to do that
LOL
hell yeah
do it
Do it
Battery hookup sells some
those pre-made ones are damn neat
You will probably need to stack though
iirc 3A/cell
yes
