This is a new variant of the LG HD2 called the HD2C.  It is a very good battery rivalling and in some cases beating a Sony VTC4.   Despite technically having a 20A rating this rating is very conservative and the battery acts similar to most 30A batteries on the market in terms of internal resistance.

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? IStick Pico

Great price quick delivery

This is a good battery at a great price. I was a little leery that the price was too good to be true. Was hands down, the best price I could find anywhere. There are better batteries out there but I think this is a good solid mid line battery. lasts plenty long enough. Came with plastic cases that hold two batteries. enough for all the batteries I purchased. Was a nice surprise.
