SVLOT Hive 21700 4400mAh 5C Flat Top Battery 2-Pack | 22A Continuous, 3.6V Li-ion for Flashlights, RC & Tools
Description
Welcome to the Hive. Smarter Power, Relentless Output.
Meet the SVLOT Hive 21700 — a 4400mAh high‑drain cell engineered to keep your most demanding devices buzzing with energy. This 2‑pack isn’t just an upgrade; it’s a complete rethinking of what a rechargeable battery can do. With a genuine 5C discharge rating (22A continuous) , the Hive cell feeds turbo flashlights, RC cars, and power tools the clean, sustained current they crave — without the dreaded mid‑use voltage sag.
Why “Hive”? Because Energy Should Work Together.
Like bees in a hive, these cells are built to collaborate. Wire them in series for a high‑voltage 2S pack. Keep one in your pocket while the other powers your gear. The 2‑pack gives you the flexibility to tackle any project, from rebuilding a drill battery to assembling a portable power station. And with 4400mAh per cell, you’re getting nearly 16 watt‑hours of energy — enough to light up a trail, film a sunset, or drive hundreds of screws on a single charge.
22 Amps, Zero Drama.
The Hive’s 5C architecture unleashes a constant 22A without breaking a sweat. Flashlight turbo mode stays blinding. RC acceleration stays brutal. Impact drivers snap stubborn bolts without stalling. Because it’s built on high‑stability NMC chemistry, voltage remains flat from 4.2V down to 2.5V. Your gear performs exactly the same on minute one as it does on minute sixty.
Flat‑Top, Unprotected, Uncompromising.
SVLOT designed the Hive cell with a completely flat positive terminal and no external protection PCB. The result? A standard 70.0mm length that slides effortlessly into the tightest flashlight tubes and the most compact tool battery shells. Removing the protection circuit eliminates extra resistance, so more of the cell’s energy actually reaches your device. You bring the 4.2V charger and the device with low‑voltage cutoff; the Hive’s built‑in PTC thermistor, safety vent, and CID handle the rest.
Built to Last, Styled to Impress.
The Hive’s distinctive honeycomb‑inspired wrapper isn’t just for looks — it represents the dense, structured energy within. Underneath, a nickel‑plated steel can take drops, vibrations, and harsh job‑site conditions in stride. Over 500 charge cycles to 70% capacity and virtually zero self‑discharge mean this cell will be powering your adventures long after generic batteries have faded.

FAQ
Q: What does 5C mean?
A: It means the cell can safely discharge at 5 times its capacity. 4400mAh × 5 = 22,000mA = 22A continuous. Plenty for most high‑drain devices.
Q: Unprotected — is that safe?
A: Yes, when used correctly. Pair with a 4.2V charger and devices with low‑voltage cutoff. The cell’s PTC, vent, and CID add built‑in safety.
Q: Flat top or button top?
A: Flat top only. This is the standard for high‑drain applications — tighter fit, lower resistance.
Q: Can I use this in an 18650 light?
A: No. 21700 is larger. Your device must explicitly support 21700.
Q: Storage tips?
A: 3.6–3.7V (~50%) in a plastic case. Check every 3 months.
