⚠ Important Safety Warnings
Improper handling or misuse of this lithium-ion battery can result in FIRE, EXPLOSION, or THERMAL RUNAWAY, causing personal injury, property damage, or death. Users must read and follow all safety guidelines before purchase and use. Click here to review the full safety guidelines.
- Critical Warning: Never carry loose batteries in your pocket, purse, or bag. Loose batteries can come into contact with metal objects like keys or coins, causing a short circuit, which may result in severe burns, fire, or explosion. Always store or transport batteries in a protective case.
- Intended Use: This battery is designed for integration into protected battery packs with a Battery Management System (BMS) or Protection Circuit Board (PCB). It is not intended for standalone use or for e-cigarettes, vaporizers, or similar devices.
-
Thermal Runaway: A chain reaction where heat from a failing battery
causes further overheating, potentially leading to fire or explosion.
- Causes: Overcharging, short circuits, physical damage, or exposure to high temperatures.
- Prevention: Use a smart charger, avoid damage, and store batteries in a cool, dry place.
- Storage & Transport: Always store batteries in protective cases to prevent accidental contact with metal objects. Never store loose batteries in pockets, purses, bags, or near conductive materials.
- Inspection: Do not use if the PVC wrapper, terminal insulator, or casing is damaged, dented, leaking, or bulging. Continued use could result in failure, fire, or explosion.
- Charging: Use a smart charger specifically designed for lithium-ion batteries and ensure the charger's voltage matches the battery's specifications. Never overcharge, over-discharge, or leave unattended while charging.
-
Prohibited Activities:
- Do not expose the battery to extreme heat, fire, or liquids.
- Do not short circuit, puncture, crush, or modify the battery.
- Do not charge or discharge beyond the manufacturer’s voltage range.
- Do not dispose of in regular trash—always recycle at approved facilities.
- Emergency Response: If a cell shows signs of thermal runaway (e.g., smoke, swelling, hissing, or heat), stop use immediately and, if it can be done safely, move it to a non-flammable surface (e.g., concrete or sand) away from combustible materials. Lithium-ion cells burn as Class B fires — use an ABC / dry-chemical fire extinguisher, or douse with large amounts of water to cool the cell and prevent the fire from spreading. Do not rely on a small spray; thorough cooling is required, and cells can reignite from residual heat, so monitor the area afterward. (Class D extinguishers are intended for lithium-metal batteries, not lithium-ion.) For any fire beyond a single small cell, evacuate and call emergency services.

Fast shipping!
I welded six 3000mah Molicels into a ~24 volt pack and have been using them to power my 6 lb. RC model plane. They work great!
Best place I have found for all your 18650 and 21700 batteries and related gear. Top notch all the way. The new battery technology is getting very good. Hitting numbers not found a few years ago on 18650 and 21700 batteries. P30B has unreal performance.
Ordered from here a few times. Always arrived pretty fast. Once, I had an issue and they were quick to resolve it. Only place to get your lithium batteries and accessories.
Super Fast Service ! Shipping was unbelievably fast. Batteries don’t seem to last as long as other brands I’ve had (after charging) I have used 6 or 7 times already and I think the max I’ve gotten from these is 6 hours.
Molicels for the win as always!
Excellent batteries. Excellent price. Excellent service. Delivery came fast, items just as described and I am happy as can be with the security for sure of ordering from 18650 Battery Store.
I rebuilt a black and decker 60v battery for my leaf blower. Now it's better than new!
Super fast shipping. Batteries packaged well. In the world of 18650's it's hard to find legit dealers. Glad to be here
Excellent batteries for my high drain flashlight!
Last linger with more amps so its a win/win!
These molicel 18650 batteries are really great and hold a charge really well.
The capacity is close enough to advertised specs. My analyzer discharges to 2.95v and at a one amp charge the difference from 2.95v to 3.3v is a matter of two or three minutes so it’s pretty much negligible. I can’t speak on the amp draw aside from what I’ve seen in flashlight reviews on YouTube which were positive. So I would certainly recommend these and will buy again.
Price was great for these batteries that work like a charm.
These batteries are perfect for my vape! They are long lasting and are powerful. I'm going to buy my second pair today. So much better than the others I've purchased.
The batteries got here quick and they work great, plus they were a great deal. I'd definitely recommend this place to anyone looking for batteries.
Can't beat these batteries for high drain flashlights and you can't beat these prices either.
It’s a battery. It powers stuff.
Fast shipping. Great batteries.
Great company. Fast shipping. Reliable. I’ve bought dozens of batteries from them. Love the high Amp Molicels!
