*Works great my **Latest.Bike** I have a bad knee so I still get exercise but the bike assists me. I am a big guy so I didn’t think it would go as fast but it works great.*
NEVER HOOK UP THE BALANCE WIRES FOR THE BMS WHILE IT IS PLUGGED INTO THE BMS, ALWAYS TEST FOR CORRECT WIRING BEFORE YOU PLUG IT IN, OTHERWISE IF WRONG IT WILL DESTROY YOUR BMS.
I like your great work And I ask you for a picture of a diagram of the wiring process, your kindness I am a beginner in assembling batteries And thank you
I have a similar BMS but I’m unsure of the wiring it to the battery? Can you clarify where the charging - negative and +positive wires are soldered on the battery and BMS board? Thanks Ray
@@raymercado3650 normally the C- is your negative lead of your charging wire, my bms only utilizes negative connections so the positive wire for the load and for charging come off of the main positive of the battery. Hope that helps some.
Hi dear I appreciate your work. I am also a solar engineer based in Serra Leon I have so much interest in your idea I have started making my own better bank but I have some challenges can you please help me.
Only one person from hundreds who has a classes teach people to see proper way to do and not got killed.Cappitalist do not give a sheet abouts life of the people.This person shouldn't be allowed to show spot welding procedures.
What’s the point of making this if you’re not going to explain to your audience what exactly you’re doing & explaining best practices with something dangerous like a battery pack build??? Seems pointless especially dealing with something that can be extremely dangerous
How many amps do you plan on pulling? You have one strip of nickel on the main positive.....so its gonna heat like a mofo past 15A...and those cells are going to take a beating if you run them at 15A
I made a 48v battery with top of the line 3100 mah cells. It was 6p 13s and I used a 40 amp bms. The wire I used was 10 gage on . Well when I put this battery in my Ebike and hit the throttle it discharges really fast up and down . When I take it out and check the voltage it’s is still around 53v . What the hell did I do wrong? If anyone knows please help
Good evening, I made a 48 volt battery, but after a full charge it does not exceed 51 volts. What is the problem? Thank you, my friend. I follow you from Egypt
Yes usually this problem arise only if you using non branded cells...trusted cells are sanyo/lgmj1/Panasonic/Samsung ...only these 4 is trusted Trusted as in with good feedbacks..other brands are questionable...
I have a 16s 8p pack .. which is a 60v 20ah system, the problem is, 5 of the groups of 8 cells only charge up to 3.5v and the other 11 groups charge to 4v ...is this a battery problem or a faulty BMS ?
An entire group of cells can only be charged as far as the weakest battery in this group. This culprit battery would then have to get hot when charging, so you can use a thermal imaging camera to see whether and which individual cells are broken. if none gets hot then maybe some fets in the bms have burned out. you may be able to find the hot cells by touching them, but that's harder than it sounds.
Hello, great video,. Do you have a wiring diagram for the batteries? I would like to build one myself but I never seen a video actually provide the diagrams. Thank you.
I have a few questions as I am new to this business. These batteries are 3.7 v 2500mAh. Doesn't 48v 10000mah happen when we make 13 serial connections and 3 parallel connections? You used 4x13 batteries in total, I'm confused.
@@Knebebelmeyer to avoid confusion i think it's best to use the nominal voltage in computations regardless of the actual voltage when fully charged. you are correct, the 3.7V in 13s will yield around that much voltage fully charged. i think the confusing part is whether to use 3p or 4p; 4p will add up the Ah, not the voltages, i.e. 2500mAh+2500mAh+2500mAh+2500mAh=10000mAh. 3p will only get 7500mAh. :)
@@illumi1011 yes thats true... why the guy in the video use the batteries like this, is his own mystic!! but there are 3.7 and 3.6V batteries outhere and both are the same! i know, its not the same, but it is! most people went for fully charged batterys, cause this is the value of most chargers! Voltage on Lithium cells is pretty much useless! you cant read something about it.
Hola, quería información. He hecho un 13s 6p con las bms que se ven en tu video. Las baterías son todas nuevas. He probado la batería en el motor eléctrico y funciona. Funciona lento pero funciona. Era solo para probar. Luego he conectado la batería al cargador Liitokala 54v 2 ah y no carga. La pregunta es: puede ser el cargador o la bms? Actualmente tengo: un lifepo4 de 48v conectado al inversor solar y un cargador de plomo de 48v. Para cargar la batería, ¿puedo conectar el cargador de plomo o conectarlo al lifepo4? ¿alternativa? Gracias
Es una de dos cosas, el cargador de las baterias esta descompuesto o las baterias estan fuera de carga eso quiero decir que las baterias tienen menos de 2.8v-3.0v casa una o la mayoria, si eso es el caso el bms no va a detectar la batteria. Tendrias que desarmar la batteria y rearmala cuando todas la baterias tengan la carga maxima de 4.2v
A battery maker told me to only use max 3.2a best is 2A charger for 10.5ah....because it's only 10.5ah...if for 21ah...can go higher ah but not 5ah...unless it's the first 30-50%...battery is complicated...lol...they sell those automatic charger from 5A to 2 to 1A charging from 30%-100%
