charging mavic battery question

[raffxj]

hi guys.

I plan on using a 'regular' power supply(CV CC to be exact).

on the battery side, which pin/s are used for charging? same + and - output? im well aware these batteries are smart and have BMS's to balance each cell.

im an fpv pilot for a few years and well-versed in hardware(and software) electronics. just recently aquired a mini 3(non pro), just the basic bundle with one battery. I was planning to diy my own 'faster' battery charger and not charge on the drone itself. Not even aware if there exists a pinout for the battery?

thanks for any info

hi. no idea for what type of mavic that is. but yeah, how/where to connect the "charging". or maybe it needs other 'data' pins or ways to accept charge.

btw attached is mini3 'regular' battery, not the long-flight one. and no idea how pinouts are

thank you! judging by those 'few' pins, then those output/s are also for charge inputs.

wonder if I2C port can be read with cp2112 module/or arduino hack. maybe(?) a future plan is to recell this with a high-quality/ampacity 18650. and possibly get more flight time.

just a follow-up question. can the mini 3 battery (+ -) pins be used as charge INPUT w/o the data lines?

I don no other mav series battery, But Mav2 series(2 pro, 2 zoom)battery is perfactly charging just connect + and - pole.

And, it support superfast charging. (17.8v 7.5A DC Power supply, Force feeding!)

You can find these traces in my old post "Powerpack Build". (Sorry! Now I have'nt mav2. now i'm use Mav 3)

raffxj,

Can you confirm the PINOUT diagram above from takeshi is the Mini 3 Pro battery and the pinouts are CORRECT?

Thanks!
