(1) How to calculate charging voltage for battery?
Normally single cell charging voltage for li-ion is 4.2V, and single cell charging voltage for LiFePO4 is 3.65V; Single cell(12V) charging voltage for lead acid battery is 14.7V, therefore charging voltages for batteries are as follows:
24V LiFePO4 battery (8 cells in series): 8x3.65V=29.2V;
24V Li-ion battery (7 cells in series): 7x4.2V=29.4V;
24V Lead acid battery (2 cells in series): 2x14.7V=29.4V
36V LiFePO4 battery (12 cells in series): 12x3.65v=43.8V
36V Li-ion battery (10 cells in series): 10x4.2v=42V
36V Lead acid(3 cells in series): 3x14.7v=44.1V
48V LiFePO4 battery (16 cells in series): 16x3.65v=58.4V
48V Li-ion battery (13 cells in series): 13x4.2v=54.6V
48V Lead acid battery (4 cells in series): 4x14.7v=58.8V
60V Lead acid battery (5 cells in series): 5x14.7v=73.5V
If your battery is different voltage, please inform us. Or if your battery is with different cells number in series, you can calculate the charging voltage yourself.
(2) Can you calculate spoke size for me for a 20' 26'28' rim
The code 16 motor is rated at 192 RPM. The code 15 is 205. The code 14 is 215. The code 13 is 230. The code 12 is 250. The code 11 is 280. The code 10 is 300. The code 9 is 335. And the code 8 is 378. That's right, mind you all of these specifications are directly from the engineers of Bafang.
(5) how much should be shipping to our country per kilo ?
you can try to place the order, our website elifebike.com can calculate shipping cost automatically before you check out.
