Why This Bundle
The Molicel P30B is built around one thing: delivering as much continuous power as possible from an 18650 cell without the voltage falling apart under load. A 30A continuous rating (36A max) paired with genuinely low internal resistance makes this one of the strongest power-to-energy cells in the 18650 format. 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 Molicel INR18650-P30B 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.

Important: Molicel's own datasheet specifies that the P30B is not intended for e-cigarette or vaporizer applications. It's built and rated for power tools, RC/motorsports, and other high-drain pack use.
Note: This is a high-drain, unprotected cell — avoid mixing with batteries of a different brand, model, or charge state, and inspect the wrap for damage before every use to prevent short circuits.
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)
XTAR VC8 – Supported Battery Types & Voltage
Compatible with 3.6V/3.7V Li-ion/IMR/INR/ICR batteries, including the Molicel P30B (18650) in this bundle:
10440, 14500, 14650, 16340, 17500, 17670, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22650, 25500, 26650
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. P30B Flat Top cells measure about 65.2mm, well within the VC8's compatible range. All 8 cells in this bundle can be charged simultaneously across the charger's 8 independent bays.
Note: The P30B's rated standard charge current is 3A. The VC8 can approach that with a single slot selected (up to 3A), while charging all 8 slots at once defaults to a gentler 0.5A per slot.
What's Included
- Molicel INR18650-P30B Flat Top Battery × 8

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 P30B is an unprotected, ultra-high-power cell intended strictly for compatible, purpose-built devices — do not use it in unauthorized or modified equipment.
- Never discharge below 2.5V or charge above 4.2V
FAQ
Q: Can the XTAR VC8 charge Molicel P30B Flat Top batteries safely? A: Yes. The VC8 automatically detects Li-ion chemistry and applies the correct charging voltage (4.2V) and current for P30B 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 P30B 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 30A continuous discharge safe for everyday devices? A: No — the P30B is an ultra-high-power cell intended strictly for devices specifically engineered for high continuous discharge, such as power tools, RC/motorsports builds, and high-drain battery packs. 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 P30B compare to the P28A? A: The P28A actually carries a slightly higher discharge rating on paper (35A vs. the P30B's 30A/36A max), but the P30B is Molicel's low-impedance follow-up — its internal resistance is roughly 60% lower than the P28A's, it supports faster 3C charging, and it holds voltage more steadily under sustained high-power loads. If raw sustained power delivery and fast charging matter more than squeezing out the last bit of capacity, the P30B is the newer, more refined option.
Q: What's in the box? A: 8 Molicel INR18650-P30B Flat Top batteries, 1 XTAR VC8 charger, a USB-A to USB-C charging cable, and a user manual.
