The Fenix ARB L18 3500 is one of the most protected Li-ion batteries on the market today. The protection circuit is built into the anode (+), with a steel cap secured by a riveting process.
As a result, the ARB-L18 3400 is completely covered by a steel shell, eliminating the potential risk of short circuits caused by collision or impact.
