Do you have a DC amp clamp meter?
Just curious if you could see the actual current going in.

Unfortunately not.

Yeah, it comes up with "invalid code" anyway from the piccies you posted.

Seach the forum for "decode LiFePO4 QR", there are a couple of other options available.

It's 4.30PM here, time to crack a beer. I've been to the dentist (impacted wisdom tooth) so I deserve one! (did I just say "one"? I meant "a few").

Only extra info I could get it the manufacturer is Gotion.

You must be in a similar time zone to me, AU?

We're GMT +7 (Thailand) so a little behind Oz.

Gotion is a big Chinese battery manufacturer. Anyway, as noted earlier I'll bet you can get replacement cells (don't need to be an exact match).
