18650 7.4v 6600mah lithium ion battery pack is real good and safe?

Shenzhen Sinoli Electronic Co.,Ltd | Updated: Mar 03, 2018

18650 7.4v 6600mah lithium ion battery pack is real good and safe?


According to the industry data, in 2018, the market of waste power battery recycling can reach 5 billion yuan scale. From 2020 to 2023, the market scale of waste battery recovery increased to 13 billion 600 million yuan to 311 billion yuan.


what will you think at this data?

are you scaring your batteries are going to die in no sooner time?

well, everything has it's dead time. sooner or later. 


take 18650 7.4v 6600mah lithium ion battery pack for example.


generally, before you get the batteries, you will also find ways to know it's cyclelife and it's performance.


while, the service man will generally give you the datus about battery working voltage and drop voltage, and protection voltage, battery power/ capacity in wh, and battery life cycle etc. 


however, after 1 year or 2 year, the battery is getting weaker and weaker. there are so many batteries in electrical vehicals, like electrical bike, electrical scooter, electrical hoverboard, electrical forklife etc.


how to deal with the garbage?

PLEASE NOTICE here. 

some died battery packs, take 7.4v 6600mah 18650 lithium ion battery pack for example. when you find it's weaker and almost dead. however, some is still workable. so some ilegal battery suppliers take the cells of 7.4v 6600mah battery pack, and then resell it to other customer asking for very cheap price market, like India etc.


so please take care with the large amount of wast batteries after being used by other people already.
