So here starts the next chapter removing the batteries out of 50 600 watt "Power Boxes", the kind people use for powering 120 volt items up to 600 watts in remote locations where there is no power or in their home in emergency situations and if your thinking 50 wow!! was he garbage bin jumping? No they were all donated to the project, the 12 volt 28Ah batteries (1400 Ah combined Ah) inside are fine, the power inverter that changes the 12 DC power to 120 AC power are damaged. Our son (age 10) helped removed these batteries and other components and has now learned his dad's art of extended product re incarnation. We also received 9 free Deka 8A22nf 63Ah (567 Ah combined)batteries for a total all batteries 1967 amp hours.Here is a video of the battery inside each of these boxes they measure (in inches) 6.5"x6.5"x5"
