⚠ 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 or box.
- 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 use in devices such as e-cigarettes or vaporizers.
-
What is Thermal Runaway?
- A dangerous chain reaction where heat generated by a failing battery causes it to overheat further, potentially leading to fire or explosion.
- Causes: Overcharging, short circuits, physical damage, or exposure to high temperatures.
- Prevention: Use a smart charger, avoid physical damage, and store batteries in a cool, dry place.
- Storage & Transport: Always store batteries in protective cases or boxes 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. These are signs of internal damage or instability, and continued use could result in failure, fire, or explosion.
- Charging: Use a smart charger designed specifically for lithium-ion batteries and ensure that the charger's voltage matches the battery's specifications. Never overcharge, over-discharge, or leave unattended while charging.
- Prohibited Activities: Do not short circuit, modify, puncture, crush, expose to liquids, or solder directly onto the battery (spot weld only).
- Emergency Response: If a cell shows signs of thermal runaway (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 combustibles. Lithium-ion cell fires are Class B fires — use an ABC/dry-chemical extinguisher, or douse with large amounts of water to cool the cell and prevent spread. 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 for lithium-metal batteries, not lithium-ion.) For any fire beyond a single small cell, evacuate and call emergency services.

Only brand i use in my stubby21 mod
Fast shipping and great product!!!
Navigable website. Easy online purchasing process. On time delivery. Package arrived on time and intact. Product was well packed and order was correct, as promised.
Works great! Arrived on time. Doesn’t appear to be b bin or re wrap batteries. I appreciate the battery case and sticker
I’ve owned the 18650 model of this battery for a couple years so I already knew this was good quality. The 21700 is an absolute beast. 1 battery lasts me the entire day. Geek Vape Aegis B100 21700 .2ohm coils 69 watts ALL DAY.
All three batteries that I ordered work great and we're exactly what was listed. However, I do have an issue that it took me 9 days to receive them and I emailed the company about it and all they bothered to do was email me back saying it looks like they were delivered today. I told them I thought that was a little excessive on time and that I felt a partial refund should be issued and they didn't even want to address that.
Great batteries awesome service fast shipping. IMR batteries has always dummy, right
Work great in my Vaporesso Armour X mod
Awesome service and delivery
Great batteries.
Only brand that lasts me all day only use ohm wrecker brand 100% worth the price
They are exactly what I was looking for!!
I bought two of these batteries. Neither one lasted more than one week. They just do not even power on my vape. I have. one old battery that I have been using. I don't know if this is the manufactures' problem or the business' but I will not be purchasing them again from here.
Best batteries from the best company. What more could you ask for?
Very nice
Very good batteries. They run great in my Vaporesso Armour!💫
These batteries last all day.
Only batteries I use.
My reason for the three stars is not about the product but with the time of delivery. I was expecting my package in 3-5 business days and received it in like 12. This is my only complaint. I will however order here again because of their inventory.
They're really great. Last a week
Their customer service is excellent! Still waiting on USPS to verify items were lost, but I'm confident it will be handled properly by seller
I bought these for my voodoo drag x and they work great! I put a charged one in before work, and I can vape at work, so I'm hitting it all day, and after 8 hours it's only around 65 or 75%. And that's a one battery mod that I keep at 65 watts. Wonderful batteries I will buy again
'Nough said!!!
Amperage seems to be more then my little mod can handle but power instant.. battery life decent
I highly recommend for Vape devices. IMR batteries excellent company to do business with and fast shipping.
I usually run anywhere from .15 to .3 ohm coils with this battery, I had previously bot one around 8 months back that still works but I’m starting to notice the charge isn’t lasting as long anymore which is expected. Certainly no complaints on my behalf.
Great. Highly recommend.
I bought the wrong battery but I did returned I looks like is a pain to return battery’s so I just kept it I bought another set
Love these batts, work great everytime, long charging life:u1F970:

I've been using iMR as my source for the 21700, and 18650's for a while now and I have never been disappointed. Fast delivery and great service.
These are my all day batteries now-on a dual set my fiance can go 2-3 days!
These are the best batteries I have used. IMR BATTERIES is the only place to get your batteries. They are awesome.
Great battery. Lasts me two days running at 100 W. Best batteries, I have yet to come across. Beats the LG, Sony, VTC. Ect..
Exactly what I needed! 5 star experience!
I'm really not a battery expert but I have used other batteries and the Hohm Tech seem to stay charged longer than others.
Nice battery.
