18650 3500mAh 3C Li-ion Cell Pakistan — High-Capacity for Solar & LED

18650 Li-ion Cell — 3500mAh | 3C | The Endurance Choice for Solar & LED

Problem: You’re building a solar bank or LED backup system, not a race bike. You need maximum runtime per cell, not 30A of raw discharge. High-drain 10C cells are overkill — and overpriced — for flashlights, USB power banks, and garden lighting.

Solution: This genuine 18650 Li-ion cell packs 3500mAh capacity with a true 3C continuous discharge rating (10.5A sustained). That’s 17% more runtime than a 3000mAh cell, with enough current headroom for LED drivers, small inverters, and moderate-drain electronics. PKR 1,000 per cell.

Which Cell Do You Need? 3C vs. 10C

Specifications

Where It’s Used

• Solar LED garden and street lights — long runtime through the night on a single charge
• USB power banks and portable chargers — 3C is more than enough for 2A–3A USB output
• High-end flashlights and headlamps — turbo modes up to 10A, then long regulated runtime
• LED strip backup banks — for loadshedding lighting with minimal cell count
• Portable medical devices and IoT gateways — stable voltage, low self-discharge
• RC transmitters and moderate-drain electronics — reliable capacity without voltage sag

Frequently Asked Questions

What does 3C mean for a 3500mAh cell?
3C means 3 × the capacity in amps. For 3500mAh, that’s 10.5A continuous discharge. This is ideal for solar banks, LED drivers, and flashlights. It is not designed for power tools or e-bikes — for those, you need the EVE 10C (30A) cell.

Is this cell protected or unprotected?
This is an unprotected flat-top cell intended for battery pack building. Any multi-cell pack requires a BMS for balancing and safety. Single-cell flashlight use should include a protected driver or user awareness of voltage limits.

Can I mix this 3500mAh cell with 3000mAh cells in one pack?
No. Always build packs with identical model, capacity, and internal resistance cells. Mixing capacities causes imbalance, overheating, and premature failure. Buy matched cells in one batch from Newon.

How do I know a 3500mAh cell is genuine?
Fake cells claiming 3500mAh+ often weigh under 40g and use bubbly wrappers. Genuine 3500mAh 18650s weigh ~48–50g. Newon sources authentic high-capacity cells — no relabelled generics, no recycled laptop pulls.

Can Newon build a custom pack with these cells?
Yes. Newon offers custom battery solutions for solar, LED, and backup projects. WhatsApp your voltage and capacity requirements for a quote.

Is free shipping and bulk pricing available?
Yes. Free nationwide shipping on 10+ cells. For solar installers, LED project contractors, or wholesale buyers, contact Newon on WhatsApp at +92 343 9227883 for bulk rates.
