Got it. When charging with powerful memory, such as from 1 amp, the charge chip is very heated. You either need to limit the voltage to 4.5 volts, as all that is higher than 4.5 for this chip, dissipates in the form of heat, or the current of the charger to limit or take charge with the charge current smaller. At 1 amp, this charging will push to the maximum, but at the same time heating the mikruhi charge is strong, so the optimal operation of the mikruhi at the current of the memory is a maximum of 700 milliampere. By setting the charge current of the video at enough. Three boards were used. One of the boards was not working-the battery voltage: 3.85, at the output when plugged. Load: 0.82 volt, without subcl. Load: 2.86 volt. The reason for the malfunction-something is not correct to protect the overcharge, overdischarge-did not understand and changed the protection chip dw01 and transistor assembly 8205a.
