Molicel INR18650-M35A 3500mAh Flat Top Li-ion Battery 2-Pack with XTAR MC2 USB Charger – High-Output Power Kit for Flashlights RC Hobbies

What's in This Bundle

• 2x Molicel INR18650-M35A, 3,500mAh, 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.

A note on authenticity: genuine M35A cells are manufactured by E-One Moli Energy Corp. (the company behind the Molicel brand). Cells sold as "OEM" through unofficial channels aren't factory-direct — buying through an authorized distributor is worth confirming if authenticity matters for your application.

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 the same 10A continuous discharge rating you'll find on its competitors. 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.

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 MC2 — Charger Specs

A realistic note on charge time: Molicel's own standard charge current for this cell is 1.7A, above the MC2's 1A per slot — expect a full charge in roughly 4.5-5 hours, both cells at once, a bit longer than lower-capacity cells since there's more capacity to fill at a more conservative rate.

Where the M35A Actually Fits

• High-capacity flashlights and headlamps — long runtime with 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
• Medical, monitoring, and industrial devices where cycle life and temperature stability matter alongside capacity
• General electronics and backup power packs prioritizing energy density with solid discharge headroom

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. Pairing cells from different ages or usage histories in a series/parallel setup can cause imbalanced charging over time.
• 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 handle the M35A's full capacity safely? Yes. The MC2's 1A per slot is below Molicel's own 1.7A standard/max charge current, so it's a conservative, safe rate — a full charge takes roughly 4.5-5 hours, both cells at once.

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.

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. 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.

In stock now. This bundle ships as a matched pair of genuine Molicel INR18650-M35A Flat Top cells with a verified XTAR MC2 charger — ready for high-capacity flashlights, cold-weather e-bike builds, and general electronics out of the box.
