I use 4 section 1.2 v rechargeable batteries to power a raspberry pie, the measured voltage at around 4.9 v, raspberries on the power near the lamp can be bright, but connected to the monitor, found the board for all, of the four batteries to 1 a, the official is said to use 5 v/2 a power supply, bosses know how to solve? Thank humbly ~

1.2 V battery should be rechargeable nimh batteries, not a lithium batteries lithium batteries should be from 3.3 V to 3.7 V,
From description to see when the load is lighter MCU can work, when load current is larger MCU cannot work normally, which can determine for battery capacity can't meet the demand of load caused by.
The solution is also very simple, 1 family usually have a cell phone charger, now choose capacity bigger charger used as MCU power supply should be able to meet, two parallel increase battery capacity, battery 3 replace certain capacity lithium battery.

Get a smart phone charger, not quick charge, generally can reach 5 v2a
