******** 800/850 series

[RadioTechnick]

Hi all.
I`m sorry for my english, i`m not from english-spoken country.

I need schematic or other info to bult home-made charger for my mtp850.
Charger have 3 pins: gnd, ext_bat+ and bat_fdbk (battery feedback?).
Without connecting bat_fdbk mtp850 found a charger (which represents a laboratory power supply) but after 3-5 minutes got an error "unknown charger".

Inside battery photo may be usefull too.


And may be somebody have a last CPS, because R6C.604.01 got an error while reading my mtp850 (application does not support codeplug version (7084 for H60PCN...)?

You cannot make charger, ******** chargers have firmware inside and radio tries to read info from charger, if it does not get info you get "UNKNOWN CHARGER" error
