TK20: where is "battery status" in hex data?

Hi, someone can help me in guess where is the battery status/percentage in this hex from tk20 Vjoycar:

283836363633303033303234373935382c445735302c3232322c312c38352c3131383638363034342c322c37363a35393a30393a35443a31303a35312a2d38332a312c30303a32313a39363a36453a39423a38382a2d38362a31312c3038303332312c31383139303629

Traccar Hex Decoder say:

(866630030247958,DW50,222,1,85,118686044,2,76:59:09:5D:10:51*-83*1,00:21:96:6E:9B:88*-86*11,080321,181906)

In my web gui I can see a wrong battery percentage.

Are you sure you see this exact message in the web app? What value do you see?

Hi Anton! Thanks For your reply.

In web app I can see a “frozen” 20%.
SMS from device say different (real) value.
I can’t undestand if a battery percentage value is present in above hex data.

Are you sure you don't have any attribute copying configured?

I don’t remember....
I have to check in config.
I’try to use the default config without personalization.
Thank you Anton.

[SOLVED]
Anton, the problem was what you said.
I removed attribute copying and now it works.
Thanks a lot For helping me!
