Frequently Asked Questions (FAQ)
Q1: What pack sizes are available?
A1: This battery is available in 1, 2, 3, 4, 5, and 10-piece packs. Please choose the variant that matches your daily usage.
Q2: Is this a high-drain battery suitable for high-power mods or electric power tools?
A2: No. This battery delivers a 4.5A continuous discharge. It is specifically designed for medium-consumption devices like flashlights, radios, and cameras. It is NOT recommended for high-wattage mods, heavy-duty power drills, or high-power RC drones, which require 15A~30A batteries.
Q3: What is the lifespan of this battery?
A3: It is designed to maintain over 80% of its 2600mAh capacity after 300 charge cycles. This means it will serve you reliably for years of daily use before needing replacement.
Q4: Is it safe to leave this battery in a flashlight for long periods?
A4: Yes, because it features a built-in dual-protection board. The PCB prevents over-discharge, protecting the battery from deep depletion, even if left inside a device.
Q5: What charger should I use?
A5: It is highly recommended to use a professional smart charger with precision voltage cut-off (like XTAR VC4, X2, etc.) to charge this 3.7V cell to its 4.2V safety limit.
