IMPORTANT:
LITHIUM ION BATTERIES ARE USED IN THIS PROJECT. LITHIUM ION BATTERIES ARE VERY GOOD IF YOU USE PROPERLY AND VERY DANGEROUS IF MISUSED. I AM NOT RESPONSIBLE FOR AND DAMAGE OR CONCERN OCCUR TO YOU BY REPLICATING MY WORKS/PROJECTS FROM ANY OF MY VIDEOS. ALL VIDEOS ARE FOR STUDY AND ENTERTAINMENT PURPOSE ONLY.

ALSO KEEP IN MIND THAT YOU CANNOT CARRY THIS POWERBANK VIA AIR IF YOU BUILT THE BATTERY PACK TOTAL CAPACITY MORE THAN 100Wh. I USED 2800Mah CAPACITY 8 BATTERIES OF 18650 WITH TOTAL 87Wh ONLY. IF NOT CARRYING TO AIRPORT YOU USE ANY CAPACITY OF 18650. ENJOY
