What's in This Bundle
- 2x EVE INR18650-35V, 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.
This listing is for Flat Top. Looking for Button Top? Click here to buy: EVE INR18650-35V Button Top + XTAR MC2 Bundle.
Why This Pairing Makes Sense
The 35V is EVE's high-capacity 18650, built for applications that prioritize runtime and energy density while still holding a genuine 10.2A continuous discharge rating — a step up in current capability from purely energy-focused cells while still delivering strong capacity. 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.

A realistic note on charge time: EVE's own quoted standard charge current for this cell is a conservative 0.68A — the MC2's 1A per slot is actually a bit faster than that reference rate, while still being a safe, moderate current for a 3,500mAh cell. Expect a full charge in roughly 4-4.5 hours, both cells at once.
Where the 35V Actually Fits
-
High-capacity flashlights and headlamps — strong runtime with enough current for moderate-to-high output modes
-
E-bike and e-scooter packs where 10.2A per cell in parallel is sufficient
-
Backup power and portable electronics prioritizing energy density
-
General battery pack builds needing more current headroom than pure energy cells while keeping high capacity
Not the right choice for sub-ohm mechanical mods, or anything regularly demanding more than 10.2A 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 labeled 35V.
-
Flat Top won't work in devices that specifically require Button Top cells — check your device's battery compartment before ordering if you're not sure which terminal type it needs.
-
10.2A is a real ceiling. Don't use these in devices that regularly demand more current than that.
Frequently Asked Questions
Is this the same as the Samsung 35E? No — different brand, different cell. This listing is EVE's INR18650-35V. If you specifically need the Samsung INR18650-35E, check our separate listing for that cell.
Can this charger handle the 35V's full capacity safely? Yes. The MC2's 1A per slot is a safe, moderate rate for this cell — a full charge takes roughly 4-4.5 hours, both cells at once.
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.
