This is part 2 with the Charge and Discharge data of the 20Ah A123 Systems Battery. This Battery is made out of 8 cells connected in series each cell is 3.2V nominal 20Ah. I used my new Panasonic DMC-G3 to take this video and sound is from Sony ICD-SX712. Equipment used on this test from load to acquisition are 2 x 100W incandescent light bulb. P4400 Kill a Watt power meter. 300W pure sine wave inverter. 100A 75mV shunt resistor. 8S 20Ah LiFePO4 Battery. BVM-8S cell voltage monitor and alarm. Wavetek model 52 digital multimeter. USB to RS232 converter. Acer 11.6" core i3 Laptop. During charge the ZXY6005 CC CV power supply + two 150W ac adapter where used. The result is that Battery is 18.3Ah capacity still not bad if it will be able to recharge close to 3000 times. ... https://www.youtube.com/watch?v=RYOZUteqNEg

This video was taken over several days last winter. Wind turbine model is P-300W Hyacinth It will output as specified 300W at 12.5m/s but with 3 blades instead of 6 it was designed with. With 6 blades you will actuality get less power at the same wind speed and that has to do with the turbulence created by the extra blades. Do not purchase a wind turbine that has more than 3 blades since that is clearly designed by someone that has no idea how to design a proper wind turbine. All those 5 and even 7 blades are just a joke. People think more blades is better and help with low winds and that is not true. If you do not have proper wind recurses in your area then better invest more in solar PV panels and do not waste money on wind turbines. Do I recommend this particular wind turbine? Yes if you have good wind resources at least similar with what I have here in Southern Saskatchewan Canada and there are no trees or tall buildings to create a lot of turbulence. It has a relatively robust construction and luckily it has 6 blades so is easy to remove 3 of them and have a symmetric 3 blades wind turbine. The other 3 can be used as reserve in case they break but I think that is highly unlikely they seems to be robust enough. But in most locations a solar PV will cost less and perform better than a wind turbine so unless you are relay sure you have good winds do not invest money in wind turbines. In winter I get the sorts of winds you seen in the video every 3 or 4 days. Some times there are days in a row with those sort of wind. The wind turbine is 24V so 12.5A in nominal 12.5m/s (45km/h) (28mph) winds. Keep in mind that half the wind speed means 8x less power so at 6.25m/s (22.5km/h) (14mph) constant not gust you only get around 37W. Also I used only about 15m (50ft) of cable (3 phase AC) from the wind turbine to the controller inside and each conductor was 8mm2 (#8 AWG) copper. While less thick copper will work fro this current 12.5A nominal (over 20A possible in high winds as you seen) the voltage drop on cable in strong winds may be enough to damage the wind turbine. Also single phase AC and DC will have the same voltage drop on the same cable thickness and at the same current. Some people have the wrong impression that AC do not require the same cable thickness as DC and is false if the same current needs to be transfered. ... https://www.youtube.com/watch?v=kR7hS58U17E

See all details about the NEW SBMS on http://electrodacus.com It is low resolution 4:3 video since this is meant for Kickstarter and this is their requirement 640x480 video. The music is from Youtube free library Josh Kirsch/Media Right Productions - Tomorrowville. Let me know what you think about the video. It will now go and upload this on Kickstarter since is a bit late and I want to be able to launch the Kickstarter in 23 February. ... https://www.youtube.com/watch?v=YQAXqNE9mQc
