⚠ 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.

Overall rating: 4.8 / 5 from 18 reviews.
They work great. Last a fairly long time in between charging.
Super fast shipping! Carefully packed. Batteries work great and the best price I have seen. Will definitely be buying my batteries here! Thanks!!!
A set hmega 18650 batteries will not charge equally, one being 100% the second 73%. This is unacceptable quality from new batteries
Quick delivery! Exactly what I ordered.
Great
I love the battery
The exact batteries I needed for my vape that last long in between charges!
It last.a while when I vape on my smok rpm 3 great battery
I've been using these batteries for a couple weeks & so far so good, no probs at all.
These are excellent batteries. i chain vape a Vaporesso 200 at 44 watts with with a Bonza at about .5 Ohms & the batteries last a good 1.5 days or more before they need recharging. I recommend them. I have been using them about 1 month. i recommend them and will buy again.
Very good quality and fair price....service and shipping is great as always....I recommend them to anyone who needs batteries..be well all
Decent battery so far
I placed an order, received what I ordered swiftly and the product does what is advertised.

I read something about these not being consistent and not ideal for battery packs, which is confusing because any professional pack builder knows you preorder a tested set that has been grouped for pack building. Or can do it the long method and capacity test each battery to select pick & choose yourself. What I am impressed with is all of these batteries surpass their labeled capacity and amperage by about ~10%. To me and the team I work with, this far outweighs variations in capacity and/or internal resistance or amperage output.
