Xiaomi M365/1S/3/Essential - 36V 19000mAh internal battery

thingiverse

Here is an opensource high quality custom internal battery for Xiaomi M365/1S/Essential/3 e-scooters. The battery multiplies your scooter range by x2.5. For example, if your current range is 15km, it will become 37km. The battery is plug and play, but requires the scooter body to be extended by about 25mm spacer. You can find the spacer in my designs. Printing guide: Step 1. Please remember that 21700 cells diameter is not exactly 21mm. It varies from 21mm to 22mm depending on the cell brand and model. That's why you have to print models "cells_diameter_tester_22.stl" and "cells_diameter_tester_21_5.stl" first, to find out which diameter is more suitable for the cells you are going to use. Step 2. If "cells_diameter_tester_21_5.stl" was better for your cells, then print the following parts: "10s4p_21700_body_21_5" - 1 piece "10s4p_21700_side_cover_21_5" - two pieces Otherwise, if "cells_diameter_tester_22.stl" was better for your cells, then print the following parts: "10s4p_21700_body_22" - 1 piece "10s4p_21700_side_cover_22" - two pieces Step 3. Print this part(it does not depend on cells diameter): "10s4p_21700_front_cover" Step 4.
