eBoard Upgrade with Samsung 30Q 10S4P flexible battery
The battery is the heart of each electric vehicle such as electric skateboards. Besides the quality also the capacity influences the price of a lithium-ion battery and thus the price of an eBoard. Therefore, we're personally just using well-known batteries brands like Samsung or Panasonic with a high cell rate. Also, the individual specs of a battery are important to know.
This flexible battery pack contains a 10S4P Samsung 30Q lithium-ion battery with 37 Volts and 439 Wh (12 Ah). It provides you with a real-world range of up to 40 km per charge. Because of the flexible enclosure design, you can also use this battery case for flexible eSkateboards with Bamboo deck. There is also a BMS (battery-management-system) included as well as a charging cable.
Samsung 30Q 10S4P Specification - Flexible Enclosure - Integrated BMS Switch - Charging port - Built-in BESTECH BMS 90A Continuous - Voltage: 37 Volts (432 Wh) - Configuration: 10s4p – 18650 - Autonomy: 12 Ah (45 km) - Charging time: 4-5 hours - Size: 455 x 141 x 24 mm - Weight: 441 g
Probably you already know, that the battery is the main factor to determine the quality and price of an eSkateboard. Therefore, it's also a part where you and many electric skateboard manufacturer can save money with but of course, this will have a big impact on the performance of your eBoard in different aspects. Let's compare a China brand battery with an LG and our Samsung battery:
China Brand Battery: 7S3P_25,2V_8,8Ah --> 222Wh Energy-Performance --> 7 cells x 3 parts = 21 cells in total (less cells = more load per cell) --> 25,2V : 7S = 3,6V per cell (Standard) --> 8,8Ah : 3P = 2,9Ah per cell (very low, no power) 3C discharge rate (Standard)
LG Battery: 10S4P_36V_10Ah --> 360Wh Energy-Performance --> 10 cells x 4 parts = 40 cells in total (good distribution) --> 36V : 10S = 3,6V per cell (Standard) --> 10Ah : 4P = 2,5Ah per cell (very low, no power) 3C discharge rate (Standard)
Samsung Battery: 10S4P_37V_12Ah --> 439Wh Energy-Performance --> 10 cells x 4 parts = 40 cells in total (good distribution) --> 37V : 10S = 3,7V per cell (Standard) --> 12Ah : 4P = 3Ah per cell (Standard) 3C discharge rate (Standard)
This shows us that even if the battery is from a famous brand manufacturer, it also can have a low cell capacity and performance. If you use a brand battery with 36 V of Samsung, LG, Sanyo or Sony, the quality is relatively better than batteries from Chinese brands. We don't recommend you buying Chinese brand batteries, even if they're cheaper. Some factories in China are also making fake brand batteries with LG or other famous brand names.
