⚠ 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.

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.

Overall rating: 4.8 / 5 from 17 reviews.
Took a Milwaukee M12 1.5ah that had a bad cell and the the voltage sense circuit was bad so it wouldn't charge. Or let the tool read the correct voltage even though all battery's were full. So tool would never work, after building it I realized this, and had to tear a working 1.5ah apart to get a good working pcb. Once I did it worked great, now I have a M12 3.0ah forge. Awesome battery's with great power. Torque Test Channel did this to a battery so if you want to see the numbers I'd look up that video. Decently fast shipping, but ordering only a few battery's with shipping made doing just one battery quite expensive.
These have been great. I made a couple 4S1P packs for a little 4in long range fpv quad. I'm getting 25-28 minutes flight time out of these Ampace JP30P1 cells. I'll definitely be grabbing some more for a planned 1S 3in build. IMR was great. Had the best price and is local to me. I'm in south houston, so I'm happy to support a houston business.
I picked these out to rebuild a Milwaukee M18 2ah battery pack that had a couple cells croak on me. These definitely perform far better than the cells that came in the pack from the factory. And, it's also a 3ah pack now in the same form factor.
It was my first experience rebuilding a pack and it went fairly smoothly. I may rebuild some more of my older tool battery packs with these in the future.
The Ampace JP01 are great cells.
IMRbatteries single International shipping option of having to use UPS in the end is the most expensive sipping method after they scam you out of up to a 45% of value brokerage fee on $30 in duties and txs. Please find a better shipping method. UPS is the worst.
I bought these to rebuild Milwaukee m12 batteries, they are by far the best cells for the job. They don’t add much capacity if any depending on which batteries your rebuilding, they still last considerably longer though if you aren’t at max output. Power intensive jobs are a breeze, they removed 200 ft lb lug nuts in half the time as 2.5HO stock batteries. Definitely the way to go if you need 18650s!
Initial testing of these cells is very encouraging. The lower cell resistance reduces heat generation during the charging and discharge cycles. Time will tell, but this should improve the life cycle of the cells due to less heat.
Although these are rated (and measure) about the same capacity as my previous batteries (Hohm life) they out perform them by about 50% - probably because of the lower internal resistance resulting in lower heat loss.
I highly recommend these batteries.
I’m sure it’s a great battery but it will not work in any of my ecig box mods in the Geekvape family. I believe they’re just a hair shorter and are not making contact properly. I bought them for that purpose only so I’m a little bummed they don’t work.
