Molicel INR18650-M35A 3500mAh 10A Flat Top Battery 6-Pack with XTAR VC4SL & MC1 Chargers – High-Output Power Kit for High-Lumen Flashlights RC Hobbies

What's in This Bundle

• 6x Molicel INR18650-M35A, 3,500mAh, Flat Top
• 1x XTAR VC4SL 4-slot LCD USB-C charger
• 1x XTAR MC1 single-slot USB-C charger
• Cables, manuals, and storage pouch included with both chargers

This bundle exists because there's no clean single charger that handles exactly 6 cells at once. Rather than force you into a mismatched combo, we've paired the 4-slot VC4SL with the compact single-slot MC1 — together they give you 5 charging slots, so 5 of your 6 cells can charge at the same time, with the last one following right behind.

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. Six cells bought together as a matched set means consistent capacity and internal resistance across the whole group. 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 VC4SL handles the bulk of the charging with its LCD display and capacity-test (grading) mode. 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 six cells match before you commit them to a build. The MC1 rounds things out as a small, genuinely portable single-slot charger — useful on its own for topping off a spare cell, throwing in a bag, or keeping in the car, not just as filler to hit a slot count.

Molicel INR18650-M35A — Battery Specs

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 (4 Slots)

XTAR MC1 — Charger Specs (1 Slot)

A realistic note on charging all 6: Molicel's own standard/max charge current for this cell is 1.7A, above the 1A per slot both the VC4SL and MC1 deliver — a conservative, safe rate across all 5 active slots. Expect a full charge in roughly 4.5-5 hours for those 5 cells, with the 6th following once a slot opens up.

Why the Capacity Test Mode Matters for a 6-Pack

Buying six 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 six cells hit their rated ~3,350mAh+, you can check for yourself across two batches of four (with the MC1 handling overflow) before building them into a series or parallel pack.

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
• 6S, 2S3P, 3S2P, 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 six

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. Both chargers enforce their 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.
• The MC1 charges one cell at 1A — it's not meant to replace the VC4SL for bulk charging, just to round out the slot count and serve as a lightweight backup charger.

Frequently Asked Questions

Can all 6 cells charge at the same time? 5 of the 6 can charge simultaneously — 4 on the VC4SL, 1 on the MC1. The 6th cell follows once a slot frees up.

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.

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.

Is this kit protected-cell compatible? Both chargers support protected 21700 cells (the VC4SL also supports protected 20700) if you use them for those later. The Molicel M35A cells included in this bundle are unprotected bare cells, standard for this model.

In stock now. This bundle ships as a matched set of six genuine Molicel INR18650-M35A Flat Top cells with a verified XTAR VC4SL and XTAR MC1 charger combo — ready for high-capacity flashlights, cold-weather e-bike builds, and general electronics out of the box.
