Hi,
So, last September I bought this: https://www.electric-skateboard.builders/t/selling-new-10s4p-battery/60410 battery from @OskarCastrone since then it hasn’t been used extensively (only about 20 to 30 cycles) since then. The battery is in my opinion pretty unsafe so I would prefer to sell it to someone who knows what he is doing.
It needs some “service” to make it safer but theoretically, it’s working perfectly. 
Asking around 120€ +shipping since I need the money for a new battery pack. 
Pics:
I can also include a 2A charger.
I would prefer to sell it within the EU because of shipping restrictions.
Just pm me if you are interested.
Thanks for reading.

yeah I meant more like what can be done to make it safer. It looks pretty good to me
Well, there’s a lack of fishpaper between the p-groups. The balance wires are improperly placed and insulated and the bms is in an unsafe place in my opinion.
Those issues are relatively easy to resolve but I honestly don’t feel comfortable doing it on my own.
In a sense that it isn’t up to the latest “forum guidelines” but it’s not like it’s about to explode…
My battery looks way way worse. Like way worse.

Those weld spots look a bit weak tbh, but hard to tell. Not gonna lie, I’m PRETTY hecking interested in buying this as a temporary battery for my next build. Not gonna go for it until I really need it though.

what range did you get out of it? Voltage sag?
Depends on your configuration but I got around 20 to 30km with it but you can easily use one of the calculators that are on here.
A bit yes.
