- Do not short circuit ( will release tremendous current )
- Do not dispose of in fire.

 This item cannot be sent to International destinations

Attention : These IMR cells have much lower internal resistance than regular LiIon 3.7V cells and they may end up with a higher ending voltage when charged in certain chargers ( especially older version WF-139 charger ). Please check the voltage of them right out of the charger to see if they are above 4.20V when fully charged with your charger. Overcharging above 4.25V may shorten life/cycles. Above 4.50V may even pop them or making them leak. DO NOT use the charger if it seems to overcharge IMR cells.


This is a claimed max 10 amp battery, if you are using this in your mods, make sure the ohms of your device does not pull more than 10 amps. 
This battery is not safe for subohm vaping.

You can use this calculator linked below (or any ohm/amp calculator) to see if your amps are too high which can ause damage to the battery or worse to your safety
