Security
The batteries have low internal resistance. The X2's fast charge is great. I trust XTAR with my protected cells.
I vape heavily and this bundle keeps me going. The X2's screen shows the charge progress, so I know when to swap.
The 3500mAh 10A rating is accurate. The X2 charges them perfectly. I use them in my thermal scope. Very satisfied.
The X2 detects the battery type instantly. The protected cells add safety. Perfect for a high-performance flashlight.
I use a regulated mod at 60W. These 3500mAh cells last noticeably longer than my 3000s. The X2's LCD tracks the capacity.
