Previous E-bike Video: https://www.youtube.com/watch?v=oYXreeuv3Jw

in this video i build the second 24v 24ah lithium battery block for my 48v 24ah bicycle battery. i built this pack from low quality 18650 cells. each 6 cell pack cost 4.99$ so thats only about 85 cents per cell. even if they are low quality that is wonderfully useful.

in this video when i say a cell is "unstable" i mean it is more likely to short out when it's voltage is dropped due to metal buildup on the plates.

the main differances between good quality cells and poor quality cells such as these are due to the cheep cells being made of lower quality materials. some of the differances include
1: lower chemical-electrical conversion efficiency
2: lower capacity
3: faster self-discharge rate
4: shorter life span
these characteristics dont ruin their functionality though, they are wonderfully useful even at the worst quality.
