Vehicle | 1991 Sears Craftman 825 Track Drive An old 1991 snowblower full of rust that i bought for cheap without original motor and that i completly rebuilt piece by piece, sanded, grinded, cleaned, repainted and baked.

Batteries | 32 A123 Systems 20Ah cells, 3.20 Volt, Lithium Iron Phosphate I built this 16s2p battery with the famous great A123 20Ah poucges. The battery is capable of 800A burst and 300A continuous. I installed a signalab 16s BMS that i modified with a 48V coil 200A contactor for higher current control. I engineered the thermal management and current sharing of the cells. thi spack is fully protected and bult to last! The LiFePo4 are excellent for cold conditions and have a constant voltage over 80% of the discharge. |

Additional Features | 100% MADE in QUEBEC !! The lithium battery pack is portable and can be removed easy. It use SB120 Anderson connectors that quick connect to the snowblower. The battery does not care if outside temp is -20 celsius or 0 celsius.. it can work hard and perform! The motor start 100% of time!! It is very silent!.. The most noise come from the snow and ice hitting the impeller and chute! I can use it at 5am or midnight and even my neiborhood will never hear it! My clothes stay clean from exhaust odor! NO NEED EXAUST =)) |
Very efficient!.. While the Arien of my neiborhood need about 1/2 gallon of gas for his driveway, I can do it with my electric snowblower for abot 0.4kWh wich represent 2 cent of electricity here in Quebec. |
