Thats the reason why I keep saying every li-ion battery you can buy has a bms!! Its there for a REASON!!! Why would anyone build a battery pack and not use one is beyond me!!!🖒🖒
I’m rookie at BMS. Quick question...Are bms only to safely charge and balance the batteries during charging time? As far as using or discharging the batteries, does the bms play a role? Ultimately, can I use my batteries on a ebike without bms and charge the batteries later on a Nitecore portable charger?
Thanks for the awesome explanation. So using a BMS confines your system to run only as well as your worst battery. Seems like there should be a better way manage the battery system. I wonder how much energy is wasted keeping things evened out.
Amazing video! I still have a question. I'm building a mini drone. I'll be using 4s lipo 1300mAh to fly it. I'd like to put a bms so that it can protect the battery from discharging too low. Do I have to worry about the amp pulled by motor?
it's been a question mark for me but i've been feeding my 3s bms with not more than 12v that means its suppose to be 4.0v each cells at less than an amp. some say charging the cells to 4.2v loses capacity overtime. i made a diy 3s ups for my router and im supplying the bms of 12.0v dc (not really a charger) plus the bms has only 1 input and output, i dont know if there's something missing on my setup which separates the charger input and the load. but im still using the diy ups for a month with a 5 or more power interruption under a minute each
Thank you for this explanation. - You show a (3s) model with only one cell per stage. When we have 2 or more cells in parallel as per stage, the BMS is not able to identify a particular cell which has a defect in that stage. Instead, all cells in that stage will be disconnected from the circuit if a failure in one of the cells in that stage happens. - Is my conclusion correct?
@@JavierCamacho So the issue still persists? Wont your parallel cells face the same issue, with discharging at different rates and eventually explode or die?
@@JavierCamacho maybe you did not get my question correctly. If the cells in series are balanced, what about the ones in parallel? Dont they face the same problem? You said before theyre handled as one big cell, so the individual voltage isn't tested?
You are saying a BMS makes the voltage of all the cells in it the same automatically? Ive been using several different systems on several sets of cells for months and Ive never seen much balancing if any to occur. If they all start out within say a volt of one another they all charge and discharge fine and the overcharge/over discharge works as tested but they never get closer in value than when they were first installed.

Gotta say thanks for the multilingual videos, lots of time and hard work but it is greatly appreciated!
Gracias J.Camacho por tu aportacion
Tremenda Leccion sobre el funcionamiento del BMS
ERES EXCELENTE INSTRUCTOR.
Very nice video and great explanation of what it does. Thanks very much. Keep up the good work.

Very cool, nice program to illustrate. Best video ever!👍👍👍👍
Thanks. God knows I needed to hear that...
@@JavierCamacho thank you for the English version.
Great explanation Javier. I’ll check out some of your BMS links.

Thank you
great video thx
Cual es el software que usas para modelar los circuitos? Es open source?

Yes you do. Your bms has to have the ability to pass enough amps to the drone.
Great info! Thanks a lot!
Great video. Does anyone know where I can get help with building my own BMS need help in the form of schematics and videos like this one?

As long as you don't push more than they can handle you'll be fine

BMS only sees 1 big cell even if you have 100 in parallel.
@@JavierCamacho So the issue still persists? Wont your parallel cells face the same issue, with discharging at different rates and eventually explode or die?
This is why you need a balancer + BMS

A balancing bms, not all bms
@@JavierCamacho Theres the rub - not all sellers provide that distinction in the information on the product
👍👍
But how do I know if my BMS is working?
