Parallel connection cable for external battery

Parallel connection cable for external battery

Connect two batteries at the same time to add capacity and therefore autonomy.
To do this, care must be taken that each battery connected in parallel must have similar characteristics and both must be at the same voltage, without exceeding a 0.3V difference between the two.
Important!!
To install batteries in parallel in Xiaomi, the charging mode must be deactivated in the firmware reprogramming.
