I guess this topic goes here? There was electronics on the other site… anyways lets keep the chit chat short and get to it!
This is probably my 4th battery build, or so, and i decided to just say fuck it…and for science lets try this budget cell. I know people had varying issues with the liitokala 30q knock offs… which still kinda intrigue me BUT the last reviews of this cell online were a year old BUT they also showed good specs “as advertised” so I pulled the trigger.
20ah was probably a bit more than I actually needed as I had a 4p 30q in my board and got about 10mi per charge of medium hard riding. A 5p from the get go would have been nicer, and a 6p just to showoff =P
At any rate I chose a 5p of the cells as insurance if the cells couldnt perform at 15amp each as advertised I could use the extra group as buffer amps… so far so good… Ill link you to my first video… its going to be a 3 part video, 2nd video is almost done… and so far after a couple weeks of riding this pack the range is great… 60 mins non stop riding and my feet fucking hurt… with 25% left to kill…
performance is the same without changing any pre pre programmed settings in my unity…
Stay tuned, as I did some discharge and temp tests on the cells…
If you like pics here some to get u going…
cells separated by variance… (up for scrutiny Im sure)
glued together…used 18650 ring insulators as I didnt find 21700 one accessible nor did i care enough
packs welded together… (yeah yeah… some sharp edges… cite longhairedboy recent post)
A cute trick i learned from another post for insulating between groups…
I’ll leave this here now but way more to come…
Lets discuss… and by discuss I dont mean my battery building skills
