We do not recommend unprotected batteries in devices that they’re not recommended to be used in, use at your own risk. Do not use adapters with these batteries. They should never be discharged below 2.5 volts or cycle life/performance will be reduce.
Use special caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough knowledge of Li-Ion rechargeable batteries in charging, discharging and assembly before use. Always charge in/on a fire-proof surface. Never leave charging batteries unattended. We are not responsible for damage if there is any modification of the batteries/chargers in any form or shape (including pack making). We are not responsible for any injury, damage, defect, permanent or temporary that may be caused by the improper use, misuse or mishandling of Li-Ion batteries and chargers. Please have a basic understanding of the batteries you are using and how to care for them properly.
