🔋 LiitoKala Lii-35A 18650 3500mAh Battery Pack
I ordered the LiitoKala Lii-35A 18650 3500mAh batteries mainly for my high-drain flashlight and vape mod. I’d heard about LiitoKala’s reputation from online forums, so this was my entry point into testing them firsthand.
Shipping was faster than expected — just under two weeks. The batteries arrived well-packaged in a plastic case, which I appreciated for storage. Upon first use, they delivered solid performance, easily holding up through extended vaping sessions and keeping my flashlight bright for hours.
Pros: Great capacity close to the advertised 3500mAh, high-drain performance (10A continuous), safe and consistent. Cons: Slightly thicker than standard cells, which might be a tight fit for some battery holders.
Compared to similar brands in the US, these are a steal — under $4 each, while Sony or LG equivalents easily hit $10+. Performance-wise, I’d say they’re 85–90% as good. Definitely met my expectations.

🔋 MJ1 18650 3500mAh + Charger Set
I chose the MJ1 18650 3500mAh high-power battery with charger because I needed a portable charging solution along with reliable cells for my cordless power tools.
The charger was basic but functional, and the batteries held up surprisingly well under heavy torque load. I tested them in my electric screwdriver and saw zero lag or overheating.
Pros: Dual-use kit is convenient, high-capacity cells, fast shipping. Cons: Charger isn’t branded and has no LCD info display — only LED indicators.
At this price, it’s great value. A set like this in the US would cost at least $20–$25. For under $12, this was a pleasant surprise. They’ve earned their spot in my tool drawer.

🔋 9800mAh 18650 Li-ion Flashlight Battery
I bought the so-called 9800mAh 18650 Li-ion battery out of curiosity — no 18650 can realistically hit that capacity. I knew the number was inflated but wanted to test the real performance.
As expected, the actual usable capacity was closer to 2000–2200mAh. That said, for low-drain flashlights or small fans, it works just fine. Great for backup, not for high-drain gear.
Pros: Dirt cheap, functional for small gadgets. Cons: Misleading labeling, low actual capacity.
Compared to name brands, it’s underwhelming but usable if you know what you’re getting. I’d buy again for low-stakes devices only.

🔋 VariCore HG2 3000mAh 20A Battery
I grabbed this HG2 18650 3000mAh from VariCore for a vape mod and portable audio gear. I’ve used HG2 cells before (aka chocolate batteries), and these performed close to authentic.
They delivered strong power output with minimal sag even at 50–60W vaping. Tested them down to 3.0V, and they held up great.
Pros: Solid performance, high discharge current (20A), real 3000mAh capacity. Cons: No storage case included, so order extras if needed.
US pricing for genuine LG HG2s is around $8–$10/cell. These came in under $4 and are almost indistinguishable from the real deal. Definitely a win.
US $5.94

🔋 VariCore NCR18650B 3400mAh Flat Top
Needed a few NCR18650B 3400mAh flat top cells for my older Panasonic fan and LED lantern. These are known for longevity over power, and they did not disappoint.
They’re slow to drain and recharge predictably. Capacity was around 3300–3400mAh when tested with Opus charger.
Pros: Excellent for long runtimes, safe chemistry. Cons: Not suited for high-drain use.
They’re widely sold in the US for around $9/cell. Got these at half the price, and they behave exactly the same. Great pick for backup lights and emergency kits.
US $4.26

🔋 HG2 3000mAh + Nickel for DIY Packs
I ordered this HG2 3000mAh combo with nickel strips for a DIY power bank I’m building. I was specifically looking for 20A discharge cells with good thermal management.
These were well-packaged and came with nickel tabs pre-cut for easy welding. After three cycles, they stabilized at 2950mAh — excellent consistency.
Pros: High-current output, includes welding materials, stable temps. Cons: Slightly longer delivery time.
Value here is unbeatable. In the US, I’d pay 2–3× more for the same combo. Will definitely reorder for my next battery pack project.
US $1.19

🔋 LiitoKala NCR18650B 34B 3400mAh Battery
This LiitoKala NCR18650B 34B battery was a test buy to compare to VariCore’s version. I used it in a headlamp I keep for camping.
Battery life was impressive — well over 4 hours on medium brightness. Feels trustworthy and safe.
Pros: Long runtime, matches listed specs, good packaging. Cons: Slightly pricier than other Chinese brands.
Still, at under $5, it’s a third of the price of US-purchased Panasonic cells. Well worth it for reliable flashlight use.
US $27

🔋 VariCore NCR18650B + Silica Gel Cable
Ordered the VariCore NCR18650B with DIY silica cable for a battery rebuild in my old robotic vacuum. Loved the included cable — it’s thick, flexible, and perfect for spot welding.
Battery capacity and voltage output were consistent. Perfect pairing for custom electronics projects.
Pros: Great value bundle, high capacity, well-labeled. Cons: Cable ends weren’t pre-tinned.
This kind of kit would cost $20+ domestically. Got everything for under $7. Definitely exceeded expectations.
US $1.2

🔋 LiitoKala 34B 3500mAh Flashlight Battery
I tested this LiitoKala 34B 3500mAh cell in a bike light I use on evening commutes. Longevity was incredible — lasted the full 2-hour ride with power to spare.
Capacity check gave 3450mAh, close enough to the mark. Discharge curve was flat, which means constant brightness throughout.
Pros: Excellent performance, nearly accurate capacity. Cons: None I could find, honestly.
At this price, it’s a top-tier flashlight battery. Easily beats US equivalents in price and performance.
US $4.78

🔋 LiitoKala HG2 3000mAh Dual Pack
I bought this HG2 dual pack for my power bank rebuild. Arrived in a hard plastic case — a small but appreciated touch.
They passed the internal resistance test and discharged cleanly down to 3V with good thermal balance.
Pros: Quality feel, accurate performance, great storage. Cons: None yet after a month of use.
In the US, this quality at this price doesn’t exist. These have become my go-to cells.
US $4.32

🔋 VariCore Pointed NCR18650B 3400mAh
Got this pointed NCR18650B cell for a headlamp that needs a button top. Fit perfectly, no rattling or connection issues.
Output was stable, and recharge time was quick (around 3 hours on 1A). It even worked in my laser pointer, which is super picky with voltages.
Pros: Button top fits rare devices, stable performance. Cons: Slightly higher cost per cell than flat-top.
Still, way cheaper than getting a US-sourced version. I plan to stock up on these for niche devices.
US $5.65

🔋 Original HG2 3000mAh Battery from VariCore
Final pick — this HG2 3000mAh from VariCore, one more variant to compare. Used it in a handheld vacuum that eats power fast.
The battery kept it running longer than expected — close to 20 minutes at full blast. That’s solid for a 3000mAh cell under heavy load.
Pros: Real capacity, high drain, no overheating. Cons: Not marked with manufacturing date.
But everything else checked out. And again, the price was unbeatable.
US $16.54
Overall Opinion:
Honestly, I went in expecting a few duds, but almost every one of these 18650 batteries met or even exceeded expectations. AliExpress is a battery buyer’s dream — if you know what you’re getting. These cells, especially from LiitoKala and VariCore, offer 70–90% of the performance of name-brand US counterparts at a fraction of the cost. I’d 100% recommend these for flashlights, vapes, DIY projects, and more. I’m already making my next shopping list.
