1. Manual measuring, please allow 1 ~ 5 mm error,thank you.
2. This product does not contain 18650 batteries.If the battery is in the wrong direction, the charging chip will be destroyed.
3. Please do not burn the program during charging. When you burn the program, please unplug the battery and verify the switch is in ON position.
4. Recommend the use of 5V 500mA charging charger, more than 5V 1A there will be fever, does not affect the normal work, but in the process of charging charging chip do not touch or carry, the measured charge charging will rise to about 60 degrees with the diode chip, no heat during normal working hours, rest assured to carry.
