The absolute lowest internal resistance cell on the market, but doesn't quite meet Vapcell specifications
This T42 cell is a rewrapped sample cell from a huge manufacturer of one of their unreleased cutting edge cells (we can't say who). It is amazingly powerful at high current. However, being samples, they do not quite meet the stated manufacturer capacity specifications. Since they are still amazing batteries, we are offering them but with modified capacity guarantees and with a lower price than we would otherwise. Snap them up while they're here because we won't be restocking!
Vapcell rates them as 4000mAh minimum when charged with a 100mA charging cut-off current. Some do meet the 4000mAh minimum but many don't, which is why these are available at a lower price. We recommend using a more typical 20mA cut-off current and with this you should see 3900mAh or more, most actually more like 3980mAh. We will not consider returns due to capacity issues unless you see below 3850mAh.

Warning: Lithium ion batteries may explode or burn due to improper use. Using these batteries for purposes not intended by the manufacturer, including outside a battery pack and/or without a BMS, may cause severe injury and damage. We are not responsible for any injuries caused by lithium ion batteries - use at your own risk.
All rechargeable batteries have inherent risks under any circumstance. Use caution with working with li-ion batteries (lithium-ion), LiPo (lithium ion polymer), and any rechargeable cells (together "rechargeable batteries"), as they have dangerous charging characteristics and are known to explode or burn if mishandled. A purchaser and user of rechargeable batteries should educate themselves on rechargeable batteries, especially as to charging, discharging, assembly, and storage. Learn more about proper storage and care for rechargeable batteries here. We are not responsible for any damage caused by the misuse or mishandling of rechargeable batteries.
Here are a few tips:
- Never completely discharge batteries (below 2.5V under load or 3V unloaded)
- Charge fully (to 4.2V) before first use
- Never charge batteries to 4.3V or above
- Do not charge unattended
- Do not store your li-ion batteries fully charged for an extended period of time (weeks or more)
- If you must store your battery, only store in a case or individual box in a cool and dry place at approximately 3.6-3.7V
- Use only high quality battery chargers
- Do not expose to heat
- Do not connect the positive contact to the negative contact without an appropriate load
- Never exceed the battery's specifications
- Never try to charge or discharge li-ion batteries with battery chargers that are not made for li-ion batteries
- Always charge these batteries on and within fireproof material
- Never leave rechargeable batteries in a recharging station unattended
- Do not use any rechargeable battery or charger if any visible damage is present, or if known mishandling, accidental or otherwise, has occurred
- Always store and transport rechargeable cells in a safe, non-conductive container (never keep a spare battery loose in a pocket, purse, etc. and always use protective cases)
- Properly dispose of all battery cells and chargers in accordance with local laws and mandates (if you're unsure, contact your local municipality)
- If a rechargeable battery overheats, hisses, or bulges, immediately quarantine the battery from any combustible materials - ideally, take the battery outside
- If a rechargeable battery catches fire, the FAA recommends pouring water or soda on the battery and surrounding areas - ideally, use a foam extinguisher to quell the fire

I haven't tested the amps but it makes my SFH55 brighter than Molicel
Probably the best battery I've bought in the past 6 or 7 years. In fact, I bought a bunch of these. I like that they are powerful and actually last me a day, and they continue to pump out sufficient amounts of electrons after several uses.
New Batteries All work
As I expected the batteries are all working fine as they should. 4/4, no duds. Plus the color matches cases was a really nice touch.
Powerful battery, fast service
Truly high amp 21700 battery used in custom flashlights to get the most out of them. Super fast service from Liion!
