(#ix5mbfa) Wow, if I buy the Ni-Fe battery system 48Volt, this would give me 10 amp Hour battery at 48 volts and cost me $1,200 for the batteries including delivery charge, and the total weight would be 25 Kg ! And get this these batteries last forever, a 100 years. You can run them down dead flat no worries and overcharge them again. And mow all day, who mows for a full 8 hours these days?
