(1) PIECE LIFEPO4WERED/USB WITH BATTERY MOOR AT http://lifepo4wered.com/ Stable 3.2 V voltage Full cycle range of 2 V – 3.6 V LiFePO4 batteries have a nominal output voltage of 3.2 V that stays stable during most of the discharge cycle. They are fully discharged at 2 V. During the charge cycle, the voltage never goes higher than 3.6 V. That's a perfect match for the operating voltage range of many 3.3 V chips. This means you can connect your 3.3 V circuits directly to a LiFePO4 battery and you don't have to burn any of your precious battery power in a voltage regulator! Other Lithium chemistries have charge voltages up to 4.2 V, requiring voltage regulation, while NiMH and NiCd only provide 1.2 V, requiring multiple cells. High power rating High discharge rate, low internal resistance LiFePO4 batteries are suitable for high power applications—some can be discharged at up to 10C! The cells we sell are optimized for high energy density instead, but they can still be discharged at up to 3C*. But wait, only 550 mAh capacity? Yes, but at a voltage of 3.2 V. The NiCd and NiMH batteries you're familiar with and have much higher mAh ratings have a nominal voltage of only 1.2 V… when they're just charged! On top of that, their output voltage drops steadily during the whole discharge cycle. Since power = voltage x current, and energy = power x time, LiFePO4 batteries are actually very competitive in power and energy density—especially since they are very light as well! Great form-factor Hardly bigger than the battery holder Solder down two terminals You're done! It really is that simple! Single sided design Flush with your board LiFePO4wered/USB™ is designed as a single sided PCB, and mounts flush to your circuit board just like a battery holder would. There's even some space for small SMT components under the battery holder. No voltage regulator needed Perfect for low power Since the voltage range during the whole charge/discharge cycle of the battery beautifully matches the voltage range of most 3.3 V electronic components, you can power your circuits directly from the battery terminals. No need for a regulator! For low power designs, this is a big deal. It is not unusual for the voltage regulator to consume orders of magnitude more power than a microcontroller when it is in sleep mode. Enough of such waste! Smart charger Keep USB connected whenever you want The LiFePO4wered/USB™ module uses a smart charging IC that provides such features as preconditioning of deeply discharged cells and a smart algorithm that monitors the battery and keeps it topped up as long as USB power is present. Keeping USB power connected is safe and will not overcharge the battery. Status LED Indicates charging status You don't need to wonder when the battery is charging, because the status LED will tell you. Conveniently located right next to the USB connector, it is easy to make this status indicator available outside your case using a light pipe or simply a hole. Fast charge option Selects charge current By default, LiFePO4wered/USB™ charges the battery with the standard charge current recommended in the battery specification, to assure the longest battery life. Charging a fully depleted battery will take about 2.5 hours. If your design requires it, you can select a higher charge current (still below the maximum specified charge current) by bridging solder jumper SJ1. This will cut the required charge time in half!
