New 20700 Size Battery From EFest!

 This newly released (fall 2017) 20700 cell from Efest is designed for cutting edge devices that take 20700 sized cells. Need a little more capacity without a big step up in size from an 18650? The Efest 20700 can reliably produce 30A of power for up to 3000mAh of capacity.

In our testing, the Efest 20700's results are nearly identical to the IJoy 20700 - a well regarded battery in its own right. These should perform well for folks that have been happy with the IJoy.

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

Great battery

This was my first 20700 battery, so I don't have much to compare it to, but it hits just as hard as my VTC 5a's, and lasts longer. I couldn't be happier.

Solid battery choice

I ordered these batts because at the time of this review they are the same batts as the Molice/Ijoy 5 leg 20700 batts. These batts are currently the second best 20700 type on the available market and are second to the Sanyo 20700A that at the time of this review are near impossible to find. Back to the batts the Efest I purchased are solid performers and imo they are near the Sony vtc5a 18650 for reliable performance with a little better mah.
