Your Questions, Answered.
Buying a 21700 shouldn't feel like decoding a secret. Here's everything you need to know about the SVLOT Hive 4400mAh 5C cell — no fluff, no filler.
How much current can this thing really push?
22 amps. Continuous. Not a pulse rating dressed up as continuous. Not a number that only works at 0°C. 4400mAh × 5C = 22A. Real math, real performance. On a turbo flashlight pulling 18–22A, voltage stays flat until thermal regulation takes over — not electrical starvation. On an RC car or impact driver, you get full torque when you need it.
How long will it last on a single charge?
Longer than your standard 4000mAh cell. You get 4400mAh per cell — roughly 15.8 watt‑hours. Translate that: about 4.5 hours of 300‑lumen flashlight medium light. A 10‑minute RC heat plus cooldown. Hundreds of screws on a rebuilt drill pack. Enough to finish what you start.
Flat top? Button top? Protected?
Flat top. Unprotected. 70.0mm standard length. This is how high‑drain cells are meant to be — no extra resistance from a protection PCB, no button interfering with tight tubes or spot welds. You need a 4.2V charger and a device with low‑voltage cutoff. The cell has built‑in PTC, vent, and CID. You handle the rest.
What's with the honeycomb wrap?
It's not just cosmetic. The Hive design reflects what's inside: a dense, structured NMC chemistry that delivers consistent voltage and long cycle life. 500+ cycles to 70% capacity. Months of storage at 3.6–3.7V without significant self‑discharge.
Will it fit my device?
If your device says "21700" and "flat top" or "unprotected" — yes. If it says "18650" — no. 21700 is larger. If it has a physical reverse‑polarity ring that blocks flat tops, you need a button top. Check your manual.
What's in the box?
Two identical SVLOT Hive 21700 cells. Use one, charge one. Build a pack. Keep a spare. Your call.

FAQ
Q: 22A continuous — verified?
A: Verified. 5C math checks out. No marketing tricks.
Q: Why unprotected?
A: Shorter. Lower resistance. Fits more devices. Use a good charger and LVP‑equipped device.
Q: Flat top only?
A: Yes. The standard for high‑drain. Tighter fit, better for welding.
Q: 18650 compatible?
A: No. 21700 only.
Q: Storage?
A: 3.6–3.7V (~50%) in a plastic case. Check quarterly.
Q: Air travel?
A: Yes. 15.8Wh per cell. Carry‑on, terminals insulated.
