Fenix 21700 4000mAh Battery

ARB-L21-4000P

The ARB-L21-4000P is a power-packed li-ion 21700 battery from Fenix that features a whopping 4,000mAh capacity and 500 charge cycles for your favorite flashlight or electronic device. The 18A max discharge rate is ideal for extremely bright flashlights like the Fenix LR35R searchlight with a 10,000 lumen turbo.

This battery can also handle up ot a 4A charge rate, allowing for lightning-quick recharging with a sufficient charger. Multiple forms of overheat, overcharge, over-discharge, and short circuit protection keep you and your devices safe.

The protection features included in this battery make it slightly longer than the average 21700 at 76mm. While most spring-loaded battery slots adjust for varying battery length, we still recommend checking with your device's user manual for battery compatibility.

Notable Features
ť 4,000mAh capacity nearly double that of comparable 18650s
ť 3 sets of overheat protection, as well as overcharge, over-discharge, and short circuit protection
ť 18A max output current for long-lasting turbo modes on flashlights
ť 500 charge cycles saves you money, and is eco-friendly
