After 2 years of building, my standUp scooter is ready. I dare to say it is pretty fast, with a top speed well over 105km/h. I dare to say it is pretty exclusive. Many, many moments of being soo tired, allmost giving up after electrocution, Police seasure, etc. But I hung in there, and happy...

Thank you my friend, I am going to watch the video, and afterwards I am going to conquer my fear and measure each indivual cel :-) First I need to watch the video, after about "4 little bad luck moments" with batteries. Some good preparation, as in not drinking several pints of larger before...

Hi.. I think the red wire you are trying to connect, is not the throttle input wire.. Black is ground, red is 5v voltage supply. The other one, most of the time it is green, is the input signal wire. That one is never 5.05v, not very likely. You are mistaking the wires, like I did many many...

I think when you have a bluetooth BMS, you can set the battery On and Off by an app on your phone. So first shut the battery down, then connect your controller to your battery... No spark, I guess! Ps: I love your soldering, it could have been me who made that! Except for me... I use about...

Hi Leffex, With this low voltages of my pack.. Except for the bms, do you think any of the batteries still can be used, or should I consider it as total loss? Greetings Bas

Hi Marcel, fellow Dutch man? :o I have had simular problems with getting a Kelly KLS through identification proces.. It needs to jumb back to 85 by itselve, and with me, it also stayed at 170. It took me a few nights, to find this solution, which worked for and many others.. But not everybody...

Hey guys, The results of me measuring voltage of the battery pack, drop a bomb on further continuety of my scooter project, I am afraid. It is just 1 more financial setback too many. Because I am kind of noob, I am afraid I made many expensive controllers and wheel engines smoke. That is part...

In this picture, the iron connection part on top is a little loose, when I press it, I can see it touch and untouch. Could that.. Be.. The.. Reason? EDIT: More pics of other side of the Pack.

Ok, I did it, conquered my fear and cut her belly open. Panasonic batteries, very bad buy till now. I Measured voltage at the connectors, 2 connectors, because 2 controllers, and they both gave 32v.. Should be 64v! Exactly half.. So I was thinking, and this nightly 'thinking' has cost me quite...

I started with the 150A Bluetooth BMS on my expensive 60v46Ah 16s13p Panasonic powerpack today.. I took all the time, to not make mistakes.. The BMs it turned out to have was a lot, bigger then we expected, also 150A,for such a small thing.. I enclosed a picture of it.. The wires in the...

So far, I am regaining trust in the halfcyear old 42Ah PowerPack. I fully charged it last night, not use it today, only 0.1 or, maybe 0.2v fallback since yesterday.. Today I took it for a spin for about 45min. Tried a bit how all new gear reacts. During my testride 14 headlights were burning(See...

Haha thank you, Zippy :) I think you mean with pins of voltmeter in the white connector.. I have done that before, but that almost went wrong.. I would like to try everything, except for direct contact with that battery.. Also now I repacked it a bit, not yet with blue foil though. I want to...

Hoi Joachim, Zit je toevallig in de buurt van Breda? Greetings Bas

Best would be to find somebody in my country who can do this 150a bluetooth BMS install for me.. And check the other pack.. But I can't find anybody.. Yes, 1 guy who will do all for 250euro maybe.. I am considering it, but he lives also far far away.. Edit: Ps: They sent me a video on how to...

Hey guys, Thank you for your replies! So last night I fully charged it, not getting hot at all.. Before with old bms, the steel battery would warm up quit a lot.. Also the voltage today is the same like last night, exactly the same when I checked, 66.9volt. Today I connected all lights, see...
