Efest rechargeable battery – flat top.

Safe chemistry LiMN means reduced risk of venting with flame or explosion. Due to the safety inherent in IMR-safe chemistry batteries, no protection circuitry is added or built-in. This provides a slightly shorter battery length to fit most mods well. To ensure longevity, allowing the battery to discharge below 2.5V is not recommended.

Please note that due to their inherent safety, IMR cells don’t have a built-in protection circuit. They should never be discharged below 2.5 volts, or cycle life/performance will be reduced. The maximum charge voltage is 4.25 volts.
