Shira Battery Technology
Lithium-Iron Phosphate (LiFePO4)
Lifetime: at least 3-4 times as many charge cycles as lead batteries
Weight: weight reduced by 75% compared to lead batteries
Efficiency: only 1-2 kWh per ice resurfacing
Performance: high discharge power and extremely high peak power
Charging time: extremely fast charging with a fast charging terminal (80 % in 60 minutes)
Maintenance: maintenance free
Energy density: high energy density - one small battery is sufficient
Temperature range: -45 °C to 85 °C(recommended: -25 °C to 55 °C)
Fast payback: due to less maintenance, high efficiency in consumption, longevity
Cost/benefit: cost-intensive purchase/long lifetime
Security: Due to their cell chemistry, LiFePO4 cells are considered to be intrinsically safe as they eliminate the risk of thermal runaway and membrane melting which can occur in other lithium-ion accumulators. Operator safety is enhanced as no toxic gases are emitted while charging.

Water Tank & Snow Bin Examples
Example: Standard Tank: 264 USG (1,000-liter) water tank & snow tank = 528 USG (2,000 liters) of water
Example: Large Tank: 357 USG (1,350-liter) water tank & snow tank = 621 USG (2,350 liters) of water
Integrated Edger
The edger is controlled conveniently and risk-free directly from the driver’s seat. The innovative horizontal suspension system with board guides ensures the edger adapts optimally to the edge contours at a constant milling depth. In addition, excess ice is efficiently and cleanly removed.
