SKYRC MC5000 Cylindrical Battery Charger and Analyzer (AA/AAA/18650)

Charging tells you when a battery is full. Capacity testing helps you see how much useful charge it can still hold. The SKYRC MC5000 does both, making it easier to spot tired cells and match sets.

If you keep a mix of AA/AAA cells for remotes and lights, plus 18650/21700 cells for flashlights or tools, the MC5000 lets you manage them from one bench-friendly unit. Four independent slots support a wide range of rechargeable battery types, including Li-ion, Li-ion HV, LiFe, NiMH, NiCd, eneloop, NiZn, RAM, LTO and Na-ion, with adjustable charge/discharge settings and readouts for capacity and internal resistance. Power it from a wall outlet or a USB-C PD source with up to 100W input.

Why choose it

• One charger for almost everything: Works with 44+ cylindrical sizes - from AAAA and AAA/AA up to 21700/32700. Spring-loaded rails make swaps quick. Up to two large cells, such as D or 32700, fit at once.
• Real analysis for your batteries: See live voltage/current curves in Charge mode, capacity readings and internal resistance to judge cell health and match sets.
• Fast, controlled charging: Up to 5.00A per slot, within an 80W total charging limit. Discharge up to 2.00A per slot, within a 20W total limit, for testing, cycling and storage prep.
• Six useful modes: Charge, Discharge, Storage, Cycle, Refresh and Break-in - available modes depend on battery type.
• App control & updates: Built-in Bluetooth works with the SKYRC app for remote monitoring and firmware upgrades.
• Extra utility on the bench: USB-C supports PD 3.0 input up to 100W to run the charger, plus PD output up to 65W to power a compatible laptop, tablet or other device. PD output takes priority over battery charging power.
• Clear, quick operation: 2.8-inch color display, scroll wheel + two buttons, status LEDs and triple-fan cooling.

Common questions:

What can I charge?
Supported rechargeable single cylindrical cells from AAAA/AAA/AA, Sub-C, C and D, plus lithium sizes like 18350/18500/18650/18700/20700/21700/26650/32600/32650/32700 and many in between. Up to two large cells (D, 32600, 32650 or 32700) fit at once. Extra-long protected cells may not fit, so check their dimensions.

How fast is it, really?
Set 0.05-5.00A per slot, subject to the 80W total charging limit. That gives you a wide range for high-capacity Li-ion cells and gentler NiMH charging. Discharge is 0.05-2.00A per slot, subject to the 20W total limit, for capacity checks or storage conditioning. Follow your battery's recommended current; maximum settings are not suitable for every cell.

Does it run on AC or USB-C?
Both. It has a built-in 100-240V AC power supply and accepts USB-C PD 3.0 input up to 100W. USB-C also provides PD output up to 65W. If you power a device from that port, the MC5000 prioritizes it before sharing the remaining power among the charging slots. The 100W figure is the input rating; battery charging is limited to 80W total.

Is there an app?
Yes - the SKYRC app for iOS and Android. Connect via Bluetooth to monitor battery data, view charging curves and perform firmware updates.

Can it prepare cells for storage or revive older NiMH?
Yes. Storage mode is available for supported lithium and Na-ion battery types. Refresh and Break-in modes help maintain NiMH, NiCd and eneloop cells; Cycle mode is also available. Results depend on battery condition.

Notes & safe use

• Do not charge primary (non-rechargeable) cells such as alkaline, zinc-carbon, CR123A/CR2.
• Select the correct battery type and follow your battery maker's recommended charge rates.
