Battery Warning

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

  • What device/application do you use this with? Wismec Reuleaux RX Machina, mechanical mod.

Fantastic batteries.

I've been using these batteries in my Reuleaux RX Machina mech mod and they're fantastic. The battery life is as expected with a mech, and they last a decent chunk of time longer than the (quality) 18650's I was using before. I feel like these batteries, at least when used in the mod I'm using them in, have very little voltage drop, but I'm careful to keep my threads and contacts clean also. The power is fantastic, and even when I'm vaping a lot they don't just die out after two hours, even when powering a dual-coil setup using some decently thick tank tread coils that could have some ramp-up time with lower power (the build rates in at about 0.15 to 0.16 ohms.) These things aren't decided by battery alone, but certainly the battery does have a big influence on experience. These batteries also charge up relatively quickly in a 2 amp charger. I feel like the five-leg positive node makes a noticeable difference. More/thicker legs on the positive node means less resistance in the battery itself. The wrapper on these batteries has also held up well so far, but it's still pretty early so I'm not saying they're indestructible or anything. I've had other brands of batteries, even very well-known, A-list brands, with wrappers that chip or crack after weeks or days of use, so wrappers that are, thus far, holding up beautifully seems to be a detail at least worth mentioning, even if not important enough to sway a decision. *I do believe the famous 'Mooch' concluded that these batteries should be considered to be 30A batteries even though they're officially labeled as 35A. It's not a big difference, but it's worth knowing for safety's sake. If I recall correctly--and I'm fairly sure I do--Mooch concluded, as of November 2018, that these were gonna be the best 20700 batteries you'll find for vaping right now.*
