    MXUS 3k-V3 Temp Sensor info? Expected readings?

    Hi all, hope you're all well today. I'm doing some testing on my new MXUS 3k v3 but I dont know what values to expect from my temperature sensor wire (white). After running freestanding for a while it read 1.24k on 20k resistance setting on my meter. I read back in the day on a forum post...

    Dillemma with battery setup for 3kw MTB full suspension frame build

    @amberwolf @nicobie @scianiac Thank you all for the thoughtful replies on this! Being realistic with the power levels I think 3000w is just for fun and not sustained. I'm moving from a 1500ish watt ~70lbs full suspension bike and just wanting a little bit more agility + power on my new mtb...

    Dillemma with battery setup for 3kw MTB full suspension frame build

    I see, things may have changed since Feb when I asked him so I'll try again. The size of the Jumbo or super shark is fine, but the issue lies with BMS as he told me they only use one type of BMS of 40A continuous and max 50/55, yet they use molicell p28a which he himself said is far more capable...

Been taking on the idea of building a 3kw hub motor bike with a downhill mtb frame (orange five) however, the full suspension frames pose a bit of a dillemma with the battery pack since the frame geometry...

    Guessed lol. Take every label with a grain of salt, just depends how reputable the company is and check if they have certifications etc. But yea it wouldn't surprise me if the company they've outsourced for the chargers has skimped out on filtering components. Now that I was told of this, it...

    Serious charger problem? Or even battery related...?

    Hi again all. After further inspection, the fan is OK and this is NOT the problem for anyone searching around.

    Bafang ultra ISIS bottom bracket? or something else?...

    Hi all, second post today; trying to push some thoughts out while they're still fresh.. Long story short I have stripped the threads on my left crank arm (non-drive side) on my Bafang ultra Alu cranks. I can't seem to find ANYTHING on these exact model of cranks for a replacement, so I am left...

    Serious charger problem? Or even battery related...?

    Hi all, hope you are well. I recently got my hands on a Bafang ultra e-bike and im loving it so far, however I am not as enthusiastic for the battery and power side of things. Not to bore everyone with words, heres the issue. When plugging in the charger and turning it on whilst connected, it...

    Bafang ultra upgrade to 2500watt

    Anyone willing to comment on reliability at this power with the ultra motor? Possibly worth getting a brass or composite replacements for the nylon gear inside if running this for a long time? Thanks all
