Professional Features, Beginner-Friendly Design
The VX2 Pro is a multifunctional smart charger built for users who need more than just charging — without the complexity. Whether you’re a hobbyist, technician, or power user, it delivers a compete battery management experience that’s easy to use, yet powerful under the hood.
Smarter Charging to Maximize Battery Life
Intelligently detects battery types and auto-matches the optimal charging method, then auto-adjusts the best charging current based on adapter power and battery status.
Li-ion: TC/CC/CV
3-stage charging method to fully charge the battery safely and efficiently.
Ni-MH: CVSA Tech
Unique CVSA Tech for higher accuracy of full-charge detection and lower battery temperature.
▼
Optional 0.25A/0.5A/1A/2A/3A
Allows manual adjustment of the current for different user needs.
* Charging current for Ni-MH and 1.5V Li-ion batteries is fixed at 0.5A.
Grad – Know Your Battery’s True Capacity
This function is ideal for:
➤ Verifying manufacturer claims
➤ Spotting aging or degraded batteries
➤ Matching cells for multi-battery setups
* The voltage is not displayed when testing the capacity of 1.5V Li-ion battery. The mWh volume of 1.5V Li-ion is the output energy after conversion loss.
Smarter Storage to Protect Batteries
VX2 Pro is the first charger to support storage function for 1.5V Li-ion batteries — smart adjusting cells to optimal voltage to reduce self-discharge, slow aging, and extend battery life.
* Use this function when batteries are stored for extended periods or shipped over long distances.
Refresh - Bring Old Ni-MH Batteries Back to Life
The capacity and performance of Ni-MH batteries decrease over time. The Refresh helps them reach their maximum possible capacity.
➤ Suitable for older or frequently used batteries. It intelligently adjusts the discharge-charge cycles based on the battery condition.
* Only for Ni-MH batteries, other batteries will be auto-charged under this function.
Quick Discharge for Battery Checks
Discharging a battery to cutoff voltage for quick capacity checking and optimal maintenance.
* After the discharge process is completed, please adjust to the charging function to prevent the battery from over-discharging.
Internal Resistance Check
Displays internal resistance for each cell — giving you deeper insight into battery health and data you can trust for smarter use and maintenance.
Low Voltage Activation
Pioneered by XTAR, this micro-current activation revives over-discharged cells more safely and effectively.
USB-C Input with Fast Charging
Recommend XTAR PD 20W adapter and original cable for max 3A fast charging.
Power-Out Memory
Keeps the mode and function settings after power interruption until you change it.
The VX2 Pro charger intelligently remembers your LiFePO4 mode setting. Even after power outages or accidental disconnections, it automatically returns to LiFePO4 mode upon power restoration, eliminating the risk of inappropriate charging parameters that could damage your valuable LiFePO4 batteries.
Full-View Display Panel
Large HTN LCD display panel, all info visible. Every slot shows voltage, current, capacity and charging status together. Simple layout, easy to read.
* During charging: Battery level bars flash upward.
* During discharging: Battery level bars flash downward.
