High-Drain Core
This robust 5,000mAh cell is engineered for consistent 15A high-drain performance, ensuring your tactical lights reach their full lumen potential. Its protected design and steel-shell riveting provide professional-grade reliability for any mission-critical gear. Its a bit longer than unprotectec cells though

Go for it!
Great high-capacity 5000mAh 21700 with 15A discharge and solid protections = perfect runtime match for L30 II and T27. Those bulk discounts make stocking up a no-brainer, especially with free shipping!

The newest addition to the Acebeam battery family.
Strong and quality battery. There seems to be little to no difference between the 5100mAh battery and 5000mAh battery. There also seems to be no difference between the 3.6 volt and 3.7 volt variations. Both are cross compatible with any light that will accept a 75mm cell.
