Shown hanging from ceiling with a 4 cell, 12.8 volt LiFePO4 battery
pack, made with the new A-123 nano-technology cells, which could
deliver up to 2,000 charge cycles if treated correctly. The LVD
circuit in the DAS1 is set to cut the power at 10 volts to prevent
over discharge of these special batteries, which is critical to good
cycle life. The dark activation feature is a nice plus.
Charging system is 100% solar powered, through a 12V lead-acid
battery, and cell balancing charger designed for lithium chemistry.
The charging station is interfaced with the CirKits.com SPC3 charge
Mounting substrate is 3/4" Marine Starboard, (polyethylene I
believe). The second fuse seen in the pic is superfluous, only there
because it existed prior to adding the DAS1.
Light is a standard screw base 12V self balasted, 9W compact
Run time is about 4.5 hours after dusk.
