Uncle Sihai’s paddleboard thruster Li-ion pack (no voice-over, caption ‘for viewing only, do not imitate’): gather the parts, lay out 18650s in 2P14S and spot weld, connect the sense wires and mark their order, cut a wiring port in the case and a charge / discharge port (XT90), before plugging in the harness check each tap with a multimeter for rising voltage to confirm the order, check the output voltage and charge to wake it if there is none, structural adhesive on the case openings for waterproofing, finished ‘14S 24Ah 120A BMS’
A music-only video, everything in captions: gather the parts; lay out the cells in 2P14S (spot weld the nickel strip); connect the sense wires; cut a wiring port in the case lid; mark the wire order (each sense wire); cut the charge / discharge port and fit an XT90; before plugging in the harness, measure again with a multimeter to confirm the soldered wire order, rising step by step; measure the output voltage, charge to wake it if there is none; smear structural adhesive over the case openings for waterproofing; finished label 14S 24Ah 120A BMS. 102 comments: every pack needs a BMS, right; how much to make one; would a BYD 3.2 cell at ¥20 each work; wouldn’t big CATL prismatic cells be better; the nickel strip can’t carry the current; ‘hand-built with an AWithZ UF20B’.
