Lightweight and handy, Wayel batteries are Lithium Ion, equipped with Samsung Cells


Lithium-Ion batteries equipped with Samusung Cells

Electric bikes are characterized by the most advanced batteries currently on the market: Lithium-Ion batteries equipped with Samsung cells, to guarantee greater quality, safety and long-life thanks to several charging cycles: up to 1,000 complete cycles. Lithium-Ion batteries are based on advanced technology that makes them small and lightweight by generating a reduced weight for the same capacity, or greater capacity for the same weight. The result is an increase in the bike’s range. Lithium-Ion batteries are handy and quickly removable; they can be recharged at any time and do not undergo memory effect, while maintaining high performance. Moreover, during charging, they provide 95% energy efficiency. Charging times range from 4 to 7 hours. If the battery is properly stored, after 500 charge and discharge cycles it ensures a residual capacity of 87% of the nominal capacity.

Safety above all

All Wayel’s batteries ensure safety as they are in accordance with to law UN38.3: Wayel’s batteries are submitted to the tests UN38.3. Precisely because they are lightweight and compact, all Wayel batteries can be easily be carried with you, so reducing the danger of theft.

All cases of Wayel’s batteries are characterized by a packing design improved in its appearance and dimension: the weight is reduced and the most suitable shape is given tothe battery case.

Test – Norma UN38.3

Find out some some battery tests required by Standard UN38.3, which guarantee the high standards of safety of Wayel batteries Wayel: - Test 1: Altitude simulation

This test simulates air transport under low-pressure conditions. The batteries are tested for at least 6 hours under temperature conditions of 20° C + -5° C and pressure conditions of 0.116 bar or less. - Test 2: Thermal test

This test simulates rapid and extreme temperature changes in order to verify the integrity of the electrical circuits, the connection and the battery itself. The batteries are tested for at least 6 hours under temperature conditions of 75° C + -2° C and within a maximum time of 30 min. The test is repeated under temperature conditions of -40° C + -2° C. The test is repeated 10 times. - Test 3: Vibration test

This test simulates various types of typical vibrations during transport. The battery is subjected to a continuous vibration, ranging from 7Hz to 200Hz, for15 minutes. The cycle is repeated 12 times, for a total of 3 hours. - Test 4: Shock test

This test simulates possible impacts during transport. The battery is subjected to an acceleration of 150 g, with a duration of 6 ms. - Test 5: External short circuit test

This test simulates an external short circuit. The battery is subjected to a short circuit condition with a total external resistance of less than 0.1 ohm at 55°C for one hour. After having passed the test, the battery is observed for an additional six hours. - Test 6: Impact test

This test simulates an impact with a given mass. The battery is subjected to an impact against a 15.8 mm diameter bar with a weight of 9.1 kg. The bar is placed at a height of 61 cm above the battery and is dropped onto its centre. - Test 7: Overcharge test

This test evaluates the battery’s ability to withstand an overcharge condition. The battery is charged using a current equal to twice the maximum continuous charge current indicated by the Manufacturer.
