Kastar MX990 four-pack for select radios

This set includes one AC wall charger and four lithium-ion batteries built as replacements for the Maas AHT-7, SystemGear MET-1000 and MET-1000-101-00, Verizon UV-X4, and Yaesu VR-160, VX-1, VX-2, VX-2E, VX-2R, and VX-3 radios. Each cell delivers 3.7 volts and 1900 milliampere-hours, rated at 7.03 watt-hours. The foldable flat plug on the charger makes storage compact for field kits or travel bags. Operators who need ready spares for those specific hand-held models will find the pack convenient.

Charger input and output limits

The charger accepts AC 100 to 240 volts at 50 to 60 hertz, so it works on mains supplies worldwide without a separate adapter. Its output is fixed at DC 4.2 volts and 600 milliamperes, meaning each battery charges at that rate and cannot be fast-charged beyond it. A red LED shows charging in progress; a green LED shows standby or full charge. Users who need simultaneous multi-bay charging or higher current for quicker turnaround cannot achieve it with this unit.

Replaces original OEM packs for listed models

The four MX990 cells directly substitute the original battery packs supplied with the Maas, SystemGear, Verizon, and Yaesu models named above. The upgrade is worth it when the original cells no longer hold a useful charge or when a team wants a single charger type for all listed radios. It does not suit radios outside that compatibility list, nor devices that require a different voltage, chemistry, or form factor.

Questions about this item

Should I choose the 4-battery pack or a single battery for my VX-2R?

The pack includes one charger and four 1900mAh batteries, giving you spares for extended shooting sessions.

What does the 7.03 Wh rating mean when the battery is inside my VR-160?

At 3.7 V the cell stores 7.03 Wh, which equals the listed 1900 mAh and powers the radio for typical daily use.

Will the AC wall charger work on 240 V mains and how fast does it charge each MX990 cell?

The charger accepts 100–240 V AC and outputs 4.2 V at 600 mA, so a full charge takes roughly three hours per battery.
