VOLTCRAFT VC-BC-4200 Carregador universal de células redondas para baterias NiMH e Li-Ion, 4 compartimentos de carga independentes, ecrã LCD, suporta AA, AAA, AAAA, 10440, 14500, 16340, 17500, 17670, 18350, 18490, 18650 VC-17665935

Most multi-chemistry chargers force you to choose between speed, compatibility, and detailed diagnostics — the VC-BC-4200 refuses that compromise. With four fully independent slots, it charges, discharges, tests, and refreshes NiMH and Li-Ion round cells from tiny AAAA to 18650, all while showing real-time voltage, current, capacity, and time on a clear LCD. Whether you're maintaining a fleet of batteries for flashlights, vapes, cameras, or DIY projects, this charger gives you laboratory-grade control in a compact desktop unit.

Highlights

• Four independent charging slots — mix different battery sizes and chemistries simultaneously
• Supports NiMH (AA, AAA, AAAA) and Li-Ion (10440, 14500, 16340, 17500, 17670, 18350, 18490, 18650)
• Selectable charging current per slot: 200 mA, 500 mA, 700 mA, or 1000 mA
• Selectable discharge current per slot: 100 mA, 250 mA, 350 mA, or 500 mA
• Four operating modes: Charge, Discharge, Refresh, and Test (capacity measurement)
• Backlit LCD displays voltage, current, capacity, and elapsed time for each slot
• Automatic battery detection with manual override for full control
• Advanced safety: overcharge protection, short-circuit protection, reverse polarity protection, and temperature monitoring
• Delta-V charging for NiMH and CC/CV for Li-Ion ensure optimal battery health
• Supports up to 20,000 mAh per slot — handles high-capacity cells with ease
• Includes external AC power adapter (100–240 V input) for worldwide use

In daily use

Place up to four batteries in any combination — the VC-BC-4200 automatically identifies each cell's chemistry and recommends settings, but you can override current and mode at any time. The large LCD keeps you informed of every parameter, so you always know whether a battery is charging, discharging, or being tested. The Refresh mode cycles NiMH cells to revive tired batteries, while the Test mode gives you an accurate mAh capacity reading — perfect for matching cells in multi-battery devices. The charger runs cool and quiet thanks to its efficient power design, and the included AC adapter means you can use it anywhere in the world.
