EVE INR18650-35V 3500mAh Button Top Li-ion Battery 2-Pack with XTAR MC2 USB Charger – High-Capacity Long-Run Power Kit for Flashlights, Outdoor Adventures
Description
What's in This Bundle
- 2x EVE INR18650-35V, 3,500mAh, Button 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 Button Top. Looking for Flat Top? Click here to buy: EVE INR18650-35V Flat 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. Button Top is the terminal type required by devices with spring-loaded battery 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.
EVE INR18650-35V — Battery Specs
| Parameter | Value |
|---|---|
| Brand & Model | EVE Energy INR18650-35V |
| Capacity | 3,500mAh nominal (3,400mAh minimum) |
| Nominal Voltage | 3.6V |
| Max Charge Voltage | 4.20V ±0.005V |
| Standard Charge | CC-CV, 0.68A, 68mA cutoff |
| Discharge Cutoff Voltage | 2.5V |
| Max Continuous Discharge | 10.2A |
| AC Impedance | <30mΩ (1kHz) |
| Charge Temperature | 0°C to 50°C (cell surface) |
| Discharge Temperature | -20°C to 60°C (cell surface) |
| Storage Temperature | 0°C to 60°C |
| Energy Density | 743 Wh/L volumetric, 252 Wh/kg gravimetric |
| Terminal Type | Button Top |
| Protection Circuit | None (unprotected cell) |
| Weight | ≤50g (typically ~47g measured) |
| Cell Dimensions | Diameter 18.35mm, Height 65.10mm |
These specs are consistent across EVE's official datasheet and multiple authorized distributors — the 10.2A discharge figure in particular shows up reliably across sources, without the kind of discrepancy we've flagged on some other cells in this category.
XTAR MC2 — Charger Specs
| Parameter | Value |
|---|---|
| Input | Type-C, 5V⎓2A |
| Charging Current | 1A per slot — both slots simultaneously, no splitting |
| Charging Method | 3-stage charging (trickle → constant current → constant voltage), 2 independent slots with automatic detection |
| End-of-Charge Voltage | 4.2V ±0.05V |
| End-of-Charge Current | <130mA cutoff |
| Operating Temperature | 0°C to 40°C |
| Dimensions | L103mm x W53mm x H30mm |
| Weight | 54g |
| Compatible Cell Sizes | 10440, 14500, 14650, 16340, 17335, 17500, 17670, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22650, 25500, 26650 (3.6V/3.7V Li-ion), including protected 21700 cells |
| Extra Feature | "0V" activation technology — can recover some over-discharged cells |
| Status Indicators | Green = standby/fully charged, Red = charging, Off/unlit = reverse polarity or abnormal insertion |
| Safety | Reverse polarity protection, short-circuit protection, 3-stage charge control |
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.
- 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.
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.
