Any pics of this?M365GUY wrote: ↑Wed Sep 01, 2021 1:57 pmWhy are people having to replace the BMS rather than just bypassing it and using during charge only? I have seen a few comments saying bypass isn't possible because all series connections go through the BMS. That doesn't even make sense. Maybe there are different versions but from what I see bypass is possible and rather simple. Only tested with no load amp draw at 2-3 but don't see anything that would indicate a issue.
This pack should be capable of a continuous amp load of 60 amps and 5-15 second bursts of close to 100. That is big power out of a fairly small and compact pack. 10s6p with LGMJ1 cells 3500ma 10 amp discharge. These cells are 7-9$ each if you can find them. Most sellers are out of stock. My guess is the Bird 2 costs bird over 1000$ usd per scooter to purchase. The tooling and casting molds to manufacture the frame I estimate cost hundreds of thousands. The bottom piece is made by aluminum extrusion and subtractive machining. I have found 2 major flaws in the design and to correct would require new tooling. ( A f**king very expensive mistake ) rental scooters need to be designed 3x as solid as you think. If you think it's good enough, double it and it might last. The big problem for bird is going to be when someone is injured when a scooter stem snaps and a review of the design is shown to have flaws that could cause injury.
Another reason they will never be profitable and will be gone in a few years.
