Samsung 30T

High 35A Continuous Discharge Rate

The Samsung 30T is a 21700 battery that can be recharged at least 250 times for longterm value! While its 3,000mAh capacity may be on the lower end, its incredibly high 35A max continuous discharge rate is what really sets it apart from other 21700 batteries. An unprotected cell with high CTR and flat top terminals is ideal for use in battery packs in high-drain devices.

Misuse of lithium ion rechargeable battery cells can pose a serious risk of personal injury or property damage.
Use caution when working with li-ion cells, as they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has appropriate understanding 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 shape or form (including but not limited to pack making). We are not responsible for any damage caused by misuse or mishandling of li-ion batteries and chargers.
No express or implied guarantee of compatibility with any device can be made. Please do your research and make sure this battery is compatible with the item you intend to use it with.
