Panasonic NCR18650-GA 3500mAh Flat Top Li-ion Battery 2-Pack with XTAR MC2 USB Charger – High-Performance Power Bundle for EDC Flashlights, Camping Lights & Drones
Description
What's in This Bundle
- 2x Panasonic NCR18650GA, 3,450mAh, Flat Top
- 1x XTAR MC2 dual-slot USB-C charger
- 1x USB-C charging cable (included with the charger)
A ready-to-go starter kit for anyone who needs two matched, genuine high-capacity 18650 cells and a compact way to charge them — no separate charger purchase, no guessing whether a charger you already own is a safe, appropriate match.
Flat Top is the NCR18650GA's native factory configuration — this is the standard, unprotected form Panasonic/Sanyo manufactures the cell in, with the full 10A discharge rating intact.

Why This Pairing Makes Sense
The NCR18650GA is one of the most popular high-capacity 18650 cells on the market — strong energy density, a genuine 10A continuous discharge rating, and a long track record in flashlights, e-bikes, and general electronics packs. Flat Top is the standard terminal type for most current devices — DIY packs, work lights, and equipment that doesn't rely on spring-loaded contacts. Buying two cells together as a matched pair means you're starting with cells from a similar batch, which matters for anything that runs cells in series or expects consistent performance between them.
The XTAR MC2 pairs well here because it charges both slots at a full 1A simultaneously, with no current-splitting trade-off for using both bays at once — a safe, comfortable rate just under this cell's 1.475A standard charge current.

A note on wrap printing: due to regulatory changes in some markets, genuine GA cells are sometimes printed with their minimum capacity (3,300mAh) on the wrap rather than the 3,450mAh typical figure — the actual cell capacity hasn't changed, it's a labeling convention. Don't assume a cell printed "3300mAh" is a lower-capacity fake; check other authenticity markers (weight, lot code, seller sourcing) rather than the printed number alone.

XTAR MC2 — Charger Specs
| Parameter | Value |
|---|---|
| Input | Type-C, 5V⎓2A |
| Charging Current | 1A per slot — both slots simultaneously, no splitting |
| Charging Method | 3-stage charging (trickle → constant current → constant voltage), 2 independent slots with automatic detection |
| End-of-Charge Voltage | 4.2V ±0.05V |
| End-of-Charge Current | <130mA cutoff |
| Operating Temperature | 0°C to 40°C |
| Dimensions | L103mm x W53mm x H30mm |
| Weight | 54g |
| Compatible Cell Sizes | 10440, 14500, 14650, 16340, 17335, 17500, 17670, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22650, 25500, 26650 (3.6V/3.7V Li-ion), including protected 21700 cells |
| Extra Feature | "0V" activation technology — can recover some over-discharged cells |
| Status Indicators | Green = standby/fully charged, Red = charging, Off/unlit = reverse polarity or abnormal insertion |
| Safety | Reverse polarity protection, short-circuit protection, 3-stage charge control |
A realistic note on charge time: the MC2's 1A per slot is just under this cell's 1.475A standard charge current — a safe, unhurried rate. Expect a full charge in roughly 4-4.5 hours, both cells at once.
Where the NCR18650GA Actually Fits
- High-capacity flashlights and headlamps — long runtime is the main draw of this cell
- E-bike and general electronics packs — a long-standing popular choice for runtime-focused builds
- Portable power and backup power applications where capacity matters more than burst current
- Goggles, radios, and similar low-to-moderate current gear
Not recommended for sub-ohm applications — this cell's 10A ceiling and energy-focused design make it a poor match for that use case specifically, even compared to other moderate-drain cells.
Things Worth Knowing Before You Use This Kit
- This is an unprotected cell. The charger enforces its own voltage and current cutoffs, but your device still needs to handle discharge-side protection.
- Don't mix these cells with older ones you already own, even if they're also GA cells. Pairing cells from different ages or usage histories in a series/parallel setup can cause imbalanced charging over time.
- Flat Top won't work in devices that specifically require Button Top cells — check your device's battery compartment before ordering if you're not sure which terminal type it needs.
- 10A is a real ceiling. Don't use these in devices that regularly demand more current than that — a dedicated high-drain cell is the safer choice for those applications.
Frequently Asked Questions
Can this charger handle the GA's full capacity safely? Yes. The MC2's 1A per slot sits just under this cell's 1.475A standard charge current — a full charge takes roughly 4-4.5 hours, both cells at once.
Why does the wrap sometimes say 3300mAh instead of 3450mAh? Some regulatory labeling requirements call for printing the minimum rated capacity rather than the typical figure. The cell's actual capacity hasn't changed — it's a labeling convention, not a different or lower-capacity product.
Will Flat Top cells work in my device? If your device uses spring-loaded, flat, or magnetic-style contacts without a raised positive terminal requirement, Flat Top is the correct choice — and it's how Panasonic/Sanyo manufactures this cell natively. If your device specifically calls for Button Top (a raised positive terminal), you'll want that version instead.
Can I charge two different battery sizes at once? Yes — the MC2's two slots operate independently with automatic size and chemistry detection, so you could charge one 18650 and a differently-sized cell (like a 21700) at the same time if needed.
What does the "0V activation" feature do? It lets the charger attempt a slow, controlled charge on cells drained deep enough that a standard charger would refuse to recognize them at all. It won't save every over-discharged cell, but it can recover some that would otherwise be written off.
