Samsung 35E 3500mAh 8A Flat Top Battery 6-Pack with XTAR VC4SL & MC1 Chargers – Comprehensive High-Capacity Power Bundle for EDC Flashlights, Portable Devices & Travel Gear

What's in This Bundle

• 6x Samsung INR18650-35E, 3,450mAh, 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 35E is Samsung's energy-focused 18650 — it trades discharge headroom for capacity, making it a better fit for devices that draw moderate, steady current rather than sharp bursts: power banks, UPS backups, low-drain flashlights, and similar gear. Six cells bought together as a matched set means consistent capacity and internal resistance across the whole group, which matters for anything running cells in series or parallel. Flat Top is the standard terminal type for most current devices — DIY packs, general electronics, 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, so you can verify all six cells' real performance in batches of four. 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.

Samsung 35E — Battery Specs

This is an energy-density cell, not a high-drain one — its 8A continuous rating is meaningfully lower than cells like the 30Q or 25R. These are genuine cells verified against Samsung's official datasheet, not rewrapped or relabeled stock.

XTAR VC4SL — Charger Specs (4 Slots)

XTAR MC1 — Charger Specs (1 Slot)

A realistic note on charging all 6: the 35E's max charge current is 2A, comfortably above the 1A per slot both the VC4SL and MC1 deliver — plenty of margin, not a cell being pushed to its limit. With the VC4SL running 4 cells and the MC1 running a 5th, you can have 5 of your 6 cells charging simultaneously in roughly 4-4.5 hours. The 6th cell either waits for a slot to open up or gets its turn on the MC1 afterward.

Where This Bundle Actually Fits

• Power banks and backup power builds — steady, moderate draw is exactly what this cell is built for
• 6-cell UPS and emergency backup packs — capacity matters more than burst current in this use case
• Low-to-moderate output flashlights and headlamps run as a matched set of six
• DIY packs (2S3P, 3S2P, 6S, etc.) where matched internal resistance across all six cells genuinely matters

Not the right fit for sub-ohm  high-output flashlights on turbo, or power tools — those applications need more discharge headroom than the 35E is rated for. If that's your use case, look at the 30Q or 25R instead.

Things Worth Knowing Before You Use This Kit

• The 35E 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 35E — run them through the VC4SL's grading mode first if you want to check consistency.
• 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.
• Don't put these in a high-drain device expecting 30Q or 25R-level current. The 35E's 8A ceiling is a real limit, not a conservative underrating.
• 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. This bundle is built to efficiently cover 6 cells, not to charge all 6 in parallel at once.

Why is the 35E's discharge rating so much lower than other Samsung 18650 cells? It's a design trade-off, not a flaw. Samsung built the 35E to prioritize capacity over current delivery, which is why it holds more energy (3,450mAh) than cells like the 30Q (3,000mAh) or 25R (2,500mAh) but delivers less continuous current (8A vs. 15A or 20A).

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.

Why include the MC1 instead of just selling 6 cells with only the VC4SL? Without a second charger, you'd be left manually rotating 2 cells through the VC4SL's 4 slots. The MC1 fills that gap with a genuinely useful, portable charger you'll likely find uses for beyond this bundle.

Can this charger tell me if a cell is underperforming? Yes — the VC4SL's grading mode charges, discharges, and recharges a cell while measuring actual delivered capacity, rather than relying on the printed rating.

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 Samsung 35E 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 Samsung 35E Flat Top cells with a verified XTAR VC4SL and XTAR MC1 charger combo — ready for power banks, backup packs, and other moderate-drain builds out of the box.
