Additional batteries for LiFePO4wered/USB or your own projects.
These are the LiFePO4 AA cells that I use in my LiFePO4wered products. Now available separately, in case you want some extras.
LiFePO4 is one of the newer lithium chemistries. Some of the advantages are a very stable 3.2V output voltage during most of the discharge cycle, high power density, low internal resistance, long shelf life, safe chemistry, wide temperature range and a high number of recharge cycles (1000+).
I have been so impressed with these batteries that I've actually begun using them as replacements for regular alkaline and NiMH AA's. Since their voltage is about double that of a regular AA battery, I use half LiFePO4, half dummy (conductor) cells such as these and they work great!
WARNING: Only use these with equipment intended to be used with LiFePO4 3.2V cells, such as LiFePO4wered/USB, or if you use them in equipment that is made for regular 1.5V AA cells, you need to do so in combination with dummies as described above to get the voltage right. Do this only if you know what you're doing, I'm not responsible if you blow up your stuff with these! :-) Also, only charge them in a charger that is made for LiFePO4, such as my LiFePO4wered/USB modules.
When purchasing this product you agree to release Silicognition LLC and all its employees from all liability relating to injuries that may occur (during activity, usage, etc.). You also agree to hold Silicognition LLC and its employees entirely free from any liability, including financial responsibility for injuries incurred, regardless of the circumstances. Although one of the safest types of lithium batteries, LiFePO4 have high power density so think about what you are doing and don't do stupid stuff!

I was one of those kids that knew what I wanted to do when I grew up, before I was even out of grade school. No, not a fire fighter or a movie star: I wanted to be an electronics engineer.
Fast forward about 30 years, through college, various positions at a chip company, a MEMS startup and a major OEM, and here I am, trying it on my own. Having gained experience in everything from system and circuit design, chip and PCB layout, and software development for everything from microcontrollers with tiny amounts of ROM to big cloud systems, I am now ready to apply all that experience to both my own designs and yours.
Contact me for all your electronics needs from system and circuit design to layout to custom firmware and software development. Partial outsourcing or turnkey. Simple or hard. Standard stuff or something that never has been done before. Let's discuss your project. If it's something I can't do, I may know someone who can, since I am also a member of the fantastic hackerspace here in Longmont, Tinkermill and have access to its resources.
