They look good. Sometimes I have to put a LOT of pressure on it to get it to click in. The only ones that were loose for me were when I softened the plastic part by mistake when soldering.

What’s the point? This is one of the easiest things to do.

I was trying to ironically point out that they are sold as loop keys but they aren’t real loop keys.

Weak. 2/10. Please try harder next time.

I think @stan wanted to point out that they are sold as loop keys but they are not even xt90S (anti spark), just regular xt90 - and that loop key is useless

Some people dont enjoy soldering

Soldering is for nerds

It’s easy and fast. And your fingers get hot in the meantime.

Get that wire outside of the shrink asap

Acido · February 16, 2020, 8:53am

They are all passive, same as your bms
All are dumping energy in to heat not transferring to other p groups

BluPenguin · February 16, 2020, 8:53am

? what’s wrong with it?

Acido · February 16, 2020, 8:55am

If the insulation gets puncured you will have a huge short

BluPenguin · February 16, 2020, 8:59am

Oh, you mean take the wire out of the PVC shrink. Yeah that could help a bit I suppose. There’s more insulation than in that picture though. That pack is due for a checkup soon actually, been a few months, I’ll see how well the current insulation inside is doing.

visnu777 · February 16, 2020, 10:05am

I just use it external and take care According to specs it IS active since it uses the supercapacitor for transferring power from one cell to another.

Maybe a dumb question, but I got some fishpaper from amazon and it’s not adhesive…should I be looking for adhesive fish paper specifically? Or is there some sort of glue that we all use on this stuff?

agentdev · February 16, 2020, 6:20pm

There are a few adhesive options on Amazon. Some of them aren’t super strong adhesive, so I just use a bit of kapton tape on the edges to stop peeling.
