⚠ 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.

This is a great product and the batteries charge quickly. They shipped my order in a timely manner.
Works good
I grabbed the wrong product but it still works well
I don't speak English.
These batteries act like the used ones we were replacing. The ones we were replacing used to last all day and then some. We decided to order new (identical) ones when the old ones would only last about 3/4 a day. These new ones only last around 3/4 a day.
They work great, we use them with our vapes and these have always been super reliable.

Pretty good life
Very good batteries and fast working
These are awesome, long, lasting batteries! Super fast shipping!
They worked great!
Works as intended
These new batteries are great. They last 2 days in my mod. These are some of the best out of the box. Lifetime is decent on these batteries as well. Over 1000 uses on previous set before they became to worn to use. .
Its a well made and I ve been Im it for almost a month and I still haven't had to recharge it. Very beneficial to my line of duty
Great batteries for a good price. Fast shipping. Will continue to shop here.
My son has been looking for these batteries for a while now finally found them and they are worth every penny
Others may shame this brand and don't know what they are missing. Run these in a mech at .18 ohms with no issue. Change out once a day. After a year I pass them to a friend to use in their controlled mod.
Even with shipping these were cheaper than anything comparable on amazon. Have been using them for a few weeks now and have had not issues, good battery life.
Hi quality long lasting. Perfect. Exactly what I wanted.
They last a while

These batteries don’t last nearly as long as the average battery.
Great batteries, fast shipping
Easy to navigate site and order. Delivered as stated. Charge Lasts me a good part of the day
Power is good. Thought they would stay charged longer. Still like them.
Fast delivery They work fine
I use 2 batteries for my vape, and a pair last well over 12 hours of normal use. Other batteries that are similar don’t last nearly as long.

No complaints about them except for the fact that the wrap is pretty thick, the batteries do not fit in any of my tube mech mods that have very tight tolerances. They fit fine in my series box mods and DNA Sigeli mods, but they don't fit in my oil rig, nemisis tube mechs and they dont fit in my noisy cricket series box.
Great batteries! I buy 4 pairs every year to use for me and my g/f's e-cigs. Strong batteries that last a great amount of time. Durable design, never have any problems. After about a year of VERY heavy use, they start to hold less of a charge and need to be replaced, but they take a long time to die.
