Re: Electric standup jetski build

A few remarks/suggestions from the screenshots provided: -Cell High protect is ok at 4.2V, but cell high recover is a bit low, meaning if after charge the battery stabilizes at a voltage higher than this then the BMS will remain shut off, not allowing you to ride. I suggest you put is a bit closer t...

Re: Conversion of a Bultaco Sherpa

... please make sure that this is ok before everything else, if a motor burns it's far less drama than a battery ... Before starting to burn, there should be a remarkable rise of the battery temperature, no? I have 2 temperature sensors in the battery, which came with the BMS, and they didnt show A...

Re: Conversion of a Bultaco Sherpa

Hmm... I dont know what an expensive BMS costs, More than ten times this price.... :wink: Orion BMS for example. The maximum continuous current is limited to 100 A (because of the controller), and the maximum short term current is limited to 270 A (because of the battery). The BMS can support more ...

Re: Conversion of a Bultaco Sherpa

Good job on swapping your BMS, plus it seems to be an interesting one I haven't heard of before, which does active balancing, a relatively rare feature on cheap BMS :thumb: But don't forget what I told you before: you need to make sure your cells can deliver that kind of current safely. This means y...

Re: Large homemade scooter

How much are they? how big? the main reason i was looking at the mobipus 72600 was because the programming looked easer and had the dash build it. it also was small enough to fit in the airbox of a crf450. i had heard of the password system but i thought you just got on password to use it, but now ...

Does anyone know if a zero 75-7 will work with the mobipus 72600? No Idea for your specific question, sorry, but all I know is that you should avoid Mobipus, unless you got the passwords somehow (in which case please be nice and share it to the world XD). But, good news maybe, I know for sure the N...

Re: My experience with Fardriver ND84530

Nice report, thanks

Those are some tiny ridiculous phase wires for a 6kw motor.... My 2kw motor phase wires are at least five times beefier. :shock:
Weird.

But as long as it works then it probably doesn't matter!

Not a lot of progress these days, but at least some I really wanted to use wrinkle paint on the BMS box, but unfortunately all my attempts failed...
