Molicel INR18650-M35A 3500mAh 10A Flat Top Battery 4-Pack with XTAR VC4SL Charger – High-Output Power Kit for High-Lumen Flashlights, RC Hobbies
Description
What's in This Bundle
- 4x Molicel INR18650-M35A, 3,500mAh, Flat Top
- 1x XTAR VC4SL 4-slot LCD USB-C charger
- 1x Type-C QC3.0 fast-charge cable, storage pouch, and manual (included with the charger)
A complete kit for anyone running a 4-cell device or building a small pack — four matched, genuine high-capacity cells paired with a charger that does more than just charge: it tests, monitors, and reports on each cell individually.
Why This Pairing Makes Sense
The M35A is Molicel's entry into the 3,500mAh-class high-capacity 18650 field, competing directly with cells like the Panasonic NCR18650GA, LG MJ1, and Samsung 35E. What sets it apart is temperature range — Molicel rates this cell for discharge from -40°C to 60°C, a genuinely wider operating window than most cells in this capacity class, alongside a genuine 10A continuous discharge rating. Four cells bought together as a matched set means consistent capacity and internal resistance across the group, which matters for anything running cells in series or parallel. 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.
The XTAR VC4SL is a real step up from a basic charger: an LCD display showing live capacity, current, and internal resistance per slot, plus a capacity-test (grading) mode that charges, discharges, and recharges a cell to verify its actual capacity rather than just trusting the label. Unlike some cells in this capacity class, the M35A's specs are consistent across Molicel's datasheet and authorized distributors — so the grading mode here is less about resolving conflicting claims and more about confirming your specific four cells match before you commit them to a build.
Molicel INR18650-M35A — Battery Specs
| Parameter | Value |
|---|---|
| Brand & Model | Molicel (E-One Moli Energy) INR18650-M35A |
| Capacity | 3,500mAh typical (3,350mAh minimum) |
| Nominal Voltage | 3.6V |
| Charge Voltage | 4.2V ±0.05V |
| Standard/Max Charge Current | 1.7A (standard 2.5hr charge time) |
| Discharge Cutoff Voltage | 2.5V |
| Max Continuous Discharge | 10A |
| Charge Temperature | 0°C to 60°C |
| Discharge Temperature | -40°C to 60°C (cell surface must not exceed 80°C; 70°C recommended thermal cutoff at high rates) |
| Energy Density | 700 Wh/l volumetric, 250 Wh/kg gravimetric |
| Terminal Type | Flat Top |
| Protection Circuit | None (unprotected cell) |
| Weight | ~48g max |
| Cell Dimensions | Diameter 18.6mm (max), Height 65.2mm (max) |
Molicel's own datasheet and matching specs from multiple authorized distributors are consistent on the core numbers here — no meaningful discrepancy on the 10A discharge rating or capacity figures, which isn't always the case in this cell category.
XTAR VC4SL — Charger Specs
| Parameter | Value |
|---|---|
| Input | Type-C, QC3.0 (9V⎓2A) |
| Charging Current (CC) | 3A×1 / 2A×2 / 1A×4 / 0.5A×4 / 0.25A×4 — steps down automatically as more slots are occupied, or can be manually adjusted within what the slot count allows |
| Charging Method | 3-stage charging (trickle → constant current → constant voltage), 4 independently monitored slots, dynamic power allocation based on input power available |
| Cut-off Voltage | 4.2V ±0.05V (Li-ion) / 1.45V ±0.1V (Ni-MH/Ni-Cd) |
| Cut-off Current | ≤120mA |
| Operating Temperature | 0°C to 40°C |
| Dimensions | L156mm x W115mm x H35mm |
| Net Weight | 212g |
| Display | Color LCD — press Mode to cycle between capacity, current, and internal resistance readouts per slot in real time |
| Special Modes | Capacity/grading mode (charge → discharge → recharge cycle to verify true capacity), storage mode (charges or discharges cells to their rated storage voltage to extend battery life), standard charge mode |
| Compatible Cell Sizes | 3.6V/3.7V Li-ion: 10440, 14500, 14650, 16340, 17335, 17500, 17670, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22650, 25500, 26650, flat-top 32650. 1.2V Ni-MH/Ni-Cd: AAA, AA, A, SC, C. Supports protected 20700/21700 cells; spring-loaded slots can also fit two 32650s and two 18650s at once |
| Safety | Reverse polarity protection (displays "Err," shows 0V, and stops automatically), auto cut-off when fully charged, multiple charge protections |
A realistic note on charge time: Molicel's own standard/max charge current for this cell is 1.7A, above the VC4SL's 1A-per-slot rate with all four bays occupied — expect a full charge in roughly 4.5-5 hours for all four cells at once, a bit longer than lower-capacity cells since there's more capacity to fill at a more conservative rate.
Why the Capacity Test Mode Matters for a 4-Pack
Buying four cells at once is exactly the scenario where verifying consistency pays off, even for a well-documented cell like this one. The VC4SL's grading mode runs each cell through a charge-discharge-recharge cycle and reports its actual measured capacity — so instead of just trusting that all four cells hit their rated ~3,350mAh+, you can check for yourself before building them into a series or parallel pack. Cells with a wider gap during testing are worth flagging rather than mixing into a tight pack build.
Where the M35A Actually Fits
- High-capacity flashlights and headlamps — a genuine 10A ceiling for moderate-to-high output modes
- E-bike and e-scooter packs — a strong option where wide temperature tolerance matters (cold-weather riding, for example)
- Cold-environment or outdoor equipment — the -40°C discharge rating is a real advantage over cells rated only to -20°C
- 4S, 2S2P, or similar DIY pack configurations where cycle life and temperature stability matter alongside capacity
- General electronics and backup power packs built from a verified, matched set of four
Not the right choice for sub-ohm mechanical mods, or anything regularly demanding more than 10A per cell — for those, a dedicated high-drain cell like the Samsung 25R or 30Q is a better match.
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 M35A — that's exactly what the grading mode is for, if you want to check compatibility before combining batches.
- 10A is a real ceiling, and cell surface temperature matters. Molicel recommends a 70°C thermal cutoff at high discharge rates — good airflow in your build still matters even with this cell's strong temperature tolerance.
Frequently Asked Questions
Can this charger really tell me if a cell is underperforming? Yes — the grading/capacity test mode charges, discharges, and recharges a cell while measuring the actual capacity delivered, rather than relying on the printed rating. It's a genuine diagnostic tool, not just a charge indicator.
What makes the M35A different from similar 3,500mAh cells like the MJ1 or NCR18650GA? The standout spec is temperature range — Molicel rates the M35A for discharge down to -40°C, wider than most competitors in this capacity class, while matching their 10A discharge rating. If cold-weather performance matters for your application, that's a genuine differentiator, not just marketing.
Do I need to charge all four cells at once? No — each of the four slots operates independently, so you can charge one, two, three, or four cells at a time, and mix different cell sizes or even NiMH batteries across the slots if needed.
What happens if I insert a cell backwards? The display shows "Err" for that slot and the voltage reading drops to 0 — the charger stops working on that slot automatically rather than attempting to charge.
In stock now. This bundle ships as a matched set of four genuine Molicel INR18650-M35A Flat Top cells with a verified XTAR VC4SL charger — ready for high-capacity flashlights, cold-weather e-bike builds, and general electronics out of the box.
