Why This Bundle
The Sony/Murata VTC6 strikes one of the best balances in the 18650 lineup — a strong 3000mAh capacity combined with a true 15A continuous discharge rating (up to 30A with temperature-limited pulses). A set this size deserves a charger that can handle every cell at once while keeping tabs on their health. This bundle pairs 8 genuine Sony/Murata VTC6 Flat Top batteries with the XTAR VC8, an 8-bay Type-C charger with real capacity testing, internal resistance detection, and independent monitoring for every slot — ready to use straight out of the box.

The Charger: XTAR VC8
-
Type-C input with QC3.0 support: up to 3A on a single bay when battery resistance is low enough
-
5 adjustable current levels: 3A×1 / 2A×2 / 1A×4 / 0.5A×8 / 0.25A×8 — manually selectable to match your charging needs
-
8 independent charging slots: each bay monitored and controlled separately
-
Real Capacity Test (Grading Mode): on CH1–CH4, the VC8 tests true capacity through a charge–discharge–charge cycle at a stable 300mA discharge current, revealing whether a battery's stated capacity is accurate
-
Storage Mode: charges or discharges batteries to their rated storage voltage to maximize battery lifespan
-
Smart Battery Type Detection: automatically identifies the battery and selects the optimal charging strategy
-
VA LCD Display: real-time voltage, current, mode, battery type, internal resistance, and charged capacity for every slot
-
Multiple Safety Protections: over-current, overcharge, over-voltage, and short-circuit protection; automatically stops after full charge; reverse-connection and over-discharge activation for protected cells
-
Built from fire-retardant PC/ABS material, with a built-in "Three-Stage Lithium Battery Charging System" (Patent No. 201720828840.6)
Note: This listing uses the XTAR VC8 (the standard 8-bay Type-C model). If you meant the VC8S — the newer PD-enabled version — let us know and we'll swap in that model's specs.
XTAR VC8 – Supported Battery Types & Voltage
Compatible with 3.6V/3.7V Li-ion/IMR/INR/ICR batteries, including the Sony/Murata VTC6 (18650) in this bundle:

Also compatible with 1.2V Ni-MH/Ni-Cd batteries: AAAA, AAA, AA, A, SC, C
End-of-charge voltage: 4.20±0.05V (Li-ion) / 1.45±0.1V (NiMH) · End-of-charge current: <120mA
Compatibility Notes
The VC8's slider-style contacts accommodate battery lengths from 32mm to 76mm, fitting Flat Top batteries securely without any adapter. VTC6 Flat Top cells measure about 65.0mm, well within the VC8's compatible range. All 8 cells in this bundle can be charged simultaneously across the charger's 8 independent bays.
What's Included
- Sony/Murata US18650-VTC6 Flat Top Battery × 8
- XTAR VC8 Charger × 1
- USB-A to USB-C Charging Cable × 1
- User Manual × 1
Safety Tips
- Store batteries in a proper case, keeping them away from loose metal objects to prevent short circuits
- Never disassemble, puncture, burn, or submerge the batteries
- Charge only with a genuine, compatible charger such as the XTAR VC8
- The VTC6 is an unprotected, high-drain cell intended strictly for compatible, purpose-built devices — do not use it in unauthorized or modified equipment
- Never discharge below 2.0V or charge above 4.2V
FAQ
Q: Can the XTAR VC8 charge Sony/Murata VTC6 Flat Top batteries safely? A: Yes. The VC8 automatically detects Li-ion chemistry and applies the correct charging voltage (4.2V) and current for VTC6 cells, with independent monitoring on each of its 8 slots.
Q: Can I charge all 8 batteries at the same time? A: Yes. The VC8 has 8 independent slots. At the default automatic setting, all 8 can charge simultaneously at up to 0.5A per slot; manually selecting a higher current level will use fewer slots at once (e.g., 3A on 1 slot, 2A on 2 slots, or 1A on 4 slots).
Q: Will Flat Top batteries sit properly in the VC8 charger slots? A: Yes. The VC8's slider-style contacts are designed to accommodate both Flat Top and Button Top cells without any adapter or modification.
Q: How do I test if a VTC6 battery has lost capacity? A: Use the VC8's Grading Mode on CH1–CH4. It runs a charge–discharge–charge cycle to measure true capacity, so you can identify batteries that no longer meet their rated mAh.
Q: Is 15A (up to 30A) continuous discharge safe for everyday devices? A: No — the VTC6 is a high-drain cell intended strictly for devices specifically engineered for high continuous discharge, such as certain high-output flashlights, and power tools. Always check your device's battery requirements before use.
Q: Does the VC8 require a special power adapter for fast charging? A: For the fastest speeds (2A/3A settings), a QC3.0-compatible USB-C adapter is required. Without QC3.0, charging current will be limited.
Q: How does the VTC6 compare to the VTC5? A: The VTC6 offers higher capacity (3000mAh vs. 2600mAh) at a lower continuous discharge rating (15A vs. 20A). It's the better pick for longer runtime, while the VTC5 is better suited to the most extreme high-current applications.
Q: What's in the box? A: 8 Sony/Murata US18650-VTC6 Flat Top batteries, 1 XTAR VC8 charger, a USB-A to USB-C charging cable, and a user manual.
