    Li-ion cells cycle ageing

    Wow, that's pretty awful. Got to check the SOC on my 30Q pack which I rarely use because the capacity dropped so fast on it :)

    Bafang BBSHD BBS02 mid drive -- Flexible OpenSource firmware

    Nice development! Is there any possibility that this would also support BBS02? I read that you got the firmware dump from a chinese website for BBSHD, so BBS02 may be reaching too far

    Desperate: Error 30H - Replaced all but the motor!

    Im having the same issue with my bbs02. Got a Error 30H code in the display, checked all cables and still no dice. The only thing that doesnt seem to work is the speed sensor because it isnt flashing red anymore - could this possibly be the problem?

    Not quite a Satiator, but $89 delivered!

    Well you meantioned the Satiator which is weatherproof, light-ish PSU which you can take anywhere. This weighs alot more (judging by the picture), bulkier and also isnt sealed against the weather - it would be stationary PSU at best

    Cheap high capacity battery

    No way man, you're saying my 9990mAh 18650 UltraFire is fake ?? :lowbatt: :banana: :banana: :o

    Cheap high capacity battery

    IMO this forum should have a rule against posting these kinda topics, how many people are going to create topics with chinese batteries asking if the capacity is real?

    Best 18650 cell for 3p 18A max

    If I were to go for high C-rate cells I would go with the cheapest ones, because most of them are likely to last only 500 cycles.

    Best 18650 cell for 3p 18A max

    If Pajda is right the cheap M29 can do 3C at 100DOD for 1k cycles

    Tesla S3X power consumption versus high power electric bike (estimates)... WTF

    I think you're all forgetting cars use AC motor and not DC, where the AC motor gets better efficiency at high speed because they hold the torque more linearly

    Li-ion cells cycle ageing

    My previous encounter with PF is that they were very saggy at 2C. Later I got the IMR chemistry 30Q's that I'm super satisfied with the sag. Now I know that they aren't comparable because 30Q is a HP cell, but I assume another IMR cell would perform identically, like Pajda mentions that the M29...

    Li-ion cells cycle ageing

    Why does LG list this cell for 500 cycles at 1.5/4A in their datasheet?

    New 14s battery pack, US18650VTC6 vs NCR18650GA

    At nkon MJ1 is only 50 cents higher than the 29E. I wouldn't call that "MUCH" higher than the HE cell, and when you need a small pack to go for as long as possible - a measly 30% higher cost does justify the higher capacity.

    Li-ion cells cycle ageing

    If the raw data is a text format (can be readable with notepad), I can make a parser to get a chart from the data

    Li-ion cells cycle ageing

    Do you think LG M36T is the same as the M36, because at nkon there's only a 5A rated M36T, that's why I'm asking about the MJ1 - because it's a 10A rated cell

    Why didn't LG MJ1 get chosen?

    I will never buy from Luna Cycle again, if I don't have to

    They didn't get that Audi R8 in the video on their channel by being a moral company I guess

    21700 Battery cell with High-Capacity

    The cheaper and a higher C rating 50E is a no-brainer

    BBS02-750W giving variable power in cycles

    It's because the unit is using PAS instead of a torque sensor. I 'programmed' my bafang with the usb cable so that PAS would always give 8A (about 250W) no matter what PAS level and it works for me, whenever I need more power I just use the throttle
