Charging the ROC - RK3399 - MEZZ - M2 - POE

gjames@smu.ca

I dug out my old RC iMax b6 lipo charger to try and charge the battery.
It can balance charge a 2 cell lipo.
On the charger there is a 3 pin balance charging socket which measures and controls the charging.
On the   ROC - RK3399 - MEZZ - M2 - POE  there is a 3 pin port marked BAT2+ BAT1+ BAT1-.
Do I connect my chargers balance charging socket to the 3 pin port on the POE board?

This is the only document I can find on the battery:
ROC - RK3399 - MEZZ - M2 - POE
3) Onboard battery (dual 7.4V lithium battery)
4) Onboard balanced charging circuit to charge the onboard battery


Thank You

Do you want to charge the battery or want to power the board?

The 3 pins socket (bat2+,bat1+,bat-) only be connected to the battery,not the charger

So as long as it is 7.4v battery it will work? Will C discharge 25c be OK?How long will 2200mah last?

Plz use the recommended battery for better stability.  The duration depends on the workload.
