thanks for your replies.

Or can be a motor problem like phase wires, hall sensor ?

then, you mean there is nothing to worry? But I have to be more fragile and carefull when gearing. it is my second day riding a mid drive and I have to understand its character to get used to it, before damage it.

here are the photos of it:

hello, I built my second e bike with Bafang bbs02 48v 750w kit ordered from BTN aliexpress on 11.11.2014 sale. I am trying to getting used to it. riding and shifting is different than hub motors. hubs like more riding bike. bafang mid drive feels more riding bicycle. but while I was testing it...

hello, please watch the video first. it will show my problem exactly. 2 of my 6s lipo packs give unstable voltage readings with cellog8 and battery medic. first of all, cellog is Ok, I checked with other packs, works fine. individual cell voltages are unstable, changing all the time but...

I wanted to buy a meanwell 24v nes350 but supplier said I need to wait for 15 day or more to receive it. than finally I purchased A.M.T. brand (exactly same looking, clone meanwell)12v 20A switching led power supply for 20usd and I adjusted voltage to 13.5v with a screwdriver. so far so good...

you are right actually but I wanted to start up like this first, anyway I always need balance charger and I did not decide yet. I stay with 14s or more battery in the future. When I am sure, may be I will switch to bms + charger setup later.

somewhere in the forum about meanwell power supply,I have seen a post says : Pay attention that this power supply will ALWAYS try to push the output to the max up to 1650W on any voltage until it taper to the adjusted desired voltage. 350w ps does not push too much for a 300w charger right? it...
