9/14/2018 6:46 AM Life time Battery cell : Recent best SAMSUNG cells made in Korea are used. 290Wh capacity pack developed by using recent SAMSUNG cells. Capacity was extended by using silicon type high capacity anode materials (Si-O) Only 90% capacity used to expend the life time. The lowest part of graph is cut to guarantee the extended life time. Battery receives lower stress by cutting this part of graph. Intelligent cell balancing ( single chip computer ) Cell balancing by accurate real time program not by circuit. AFE IC Accurate cell status measurement. Extremely sensitive resistor Battery remained capacity is measured by 0.5% extremely sensitive resistance. © 2007 Microsoft Corporation. All rights reserved.

Shock-proof 8pcs of bolts used to join two casings strongly 9/14/2018 6:46 AM Shock-proof PC ( Poly Carbonate) used Never broken by using PC. Drop test passed ( over 10 times dropped over 2m height) Anti-fire material adapted (Fire-proof V0 grade) Cell holder inside Impact resistance is improved by strong cell holder. Cell holder makes cells have a accurate gap between cells, so it prevents cells from being short and heat from being increased. 8pcs of bolts used to join two casings strongly 8pcs of bolts are very effective when it is dropped. Even 6pcs of bolts can not prevent the pack from being split when it is dropped from 2 m height. Reinforced joint parts Joint parts are male and female-shaped. Reinforced joint parts + 8pcs of bolts guarantee strong joint. © 2007 Microsoft Corporation. All rights reserved.

9/14/2018 6:46 AM Temperature features Minimizing the heat through main output with low impedance and low resistance by large pattern. Each ends +, - are wide enough to prevent the heat when you use very high current continuously max. 12A. High heat will reduce the life time of cells and capacity (Other company’s product) Narrow each end +, - increases the heat when you use high current. When drawing 12A from main connector When drawing 12A from main connector, its temperature is about 49℃, so you don’t need to worry about the damage by heat on main connector. No wire design minimizes the impedance. No-wire design can minimize the heat inside and maximize the efficiency of current. © 2007 Microsoft Corporation. All rights reserved.
