  1. Here are the links to each of my blog entries. This index will be updated as new entries are added. You are responsible for your own safety! These batteries are designed, manufactured, and sold only for use in a battery pack with the proper protection circuitry and battery management system....
  2. DO NOT CLICK ANY OF THE LINKS BELOW UNLESS YOU FULLY UNDERSTAND AND AGREE WITH THE FOLLOWING ITEMS IN RED: My test results only represent the chargers I tested. Charger design can change or assembly quality can vary. Any charger can fail at any time, either from an internal issue or from a...
  3. Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. You are responsible for your own safety! The Li-Ion batteries we use are designed only for use in a battery pack with the proper physical and electronic protection. They were not meant...
  4. They are meant only to give you an idea of the risk if a battery is accidentally discharged at beyond its continuous current rating when vaping. You should not consider them as a rating for the battery that you can vape at! If properly used the MVA limit can help increase our safety. But it has...
  5. You are responsible for your own safety! These batteries are designed, manufactured, and sold only for use in a battery pack with the proper protection circuitry and battery management system. They were not designed for vaping (electronic cigarette) use or for use without protection circuitry....

  7. It's widely believed that the LiPo battery packs used in DNA200/250 and custom box mods need to be charged/discharged several times before they reach their peak performance. Is this true? To find out I took three new 3S packs and balanced charged them at 5A on an iCharger106B+ to 12.60V...

  9. It's time to put this myth to rest. Using rice to help dry batteries or a mod that got wet doesn't help at all. In fact, it slows down evaporation of any water that is inside. I set up a 24 hour test using paper towel sheets with enough water added to bring their weight to 18 gms. I then put...
  10. Some chargers, like the Efest LUC V4, can be used to charge batteries that have dropped to very low voltages, below 2.5V. While this is tempting there is a risk when doing this. When a Li-Ion battery drops below 2.0V or so the copper electrode inside of it literally starts to dissolve. When the...
  11. PBusardo was kind enough to offer me a page on his web site and I jumped at the chance. The first article is up. Thank you for this opportunity Phil! http://www.tasteyourjuice.com/wordpress/the-battery-mooch
  12. Even though the Sony VTC4 is still in production and genuine ones are available there are vapers who are uncomfortable taking a chance at buying counterfeit Sony batteries. Could the 22A-25A rated LG HD2, HD2C, and HD4 be as good as the Sony VTC4? Let's find out. In the graphs below I...
  13. Those are lithium-ferrous-phosphate batteries, or "LFP". They are also called IFR. They are a different type of Li-Ion chemistry than the ones we use most often when vaping, often called IMR, INR, and ICR. The continuous discharge current specifications for these batteries seem to be perfect...
  14. It's tempting to use very high capacity batteries, over 3000mAh, to try to get more vaping time before needing to recharge. But there aren't any 18650 batteries with a capacity over 3000mAh that have a rating above 10A! Batteries like the Panasonic 3200mAh NCR18650B look like a great way to get...
  15. If you want to start going beyond what www.batteryuniversity.com covers here are a few of the more interesting papers I've read on Li-Ion batteries. They are quite technical though! Thermal runaway caused fire and explosion of lithium ion battery:...
