Lithium batteries can be dangerous if mistreated or mis-used.  If you are re-selling these cells – it is your duty to educate your customers on the points below.

Always use a case for safe storage when not in use. Never in your pocket, purse etc. Keep away from keys, coins and small metallic objects.

Batteries should never be charged in a mod. It’s good practice to charge batteries on an external charger that is correctly rated for Li-Ion cells. Never leave them charging unattended and they should be removed when fully charged.

Batteries should be periodically inspected for tears and rips. Never use a batteries with a damaged PVC wrap, either recycle the cell or repair immediately. 

Do not over-stress these batteries. Batteries should be suitable for the application (correct size, amp draw etc).

The user assumes all associated risks.
