Thanks .. from italy ! 💙

I used this BMS to make a 5S1P Li-Ion battery for a drill. I have connected the P and C ports together, as it suggests you can do in the documentation. It seems to charge ok, but in this configuration, I am able to run the battery all the way down to 8V. I expected it to shutdown the battery at 13.6V (2.72V*5). Do I need to have the Load and Charge Circuits separated to protect the battery from Over Discharge?

Greate video , a big like for you sir 😊

Hello! Thanks for sharing. What is the IC you are using for balancing?

Hello, how about I build this bps with 1p and when I connect it to the 20v source, the b3 and the retso always blink, the batteries were all in the 3.25 environment, what will I be doing by balancing the plate? What should I wait for hours?

Thank you for the informative video. I was thinking about pulling out the battery pack of electric scooter to manually balance the cell groups. I have no idea about the BMS model. I'm sure it's a cheap resistive balancing BMS. Do you think applying the same voltage to the charge port and with very low current like 20-30 mA do the balancing without pulling out the battery pack? I guess you did exactly same in your video.

Thanks mate

It is good BMS I used for a cordless string trimmer that convertered to lipo

1st class video. Thanks.

Yo! Is there a minimum req. of power to charge the batteries? Is the 21 volt the minimum in this case? I was thinking of a way to add a small solar panel to an e-bike set that would charge individual batteries. Like in your case you need 21volt and i suspect the circuit eats some parts and charges all of them. But there might be a way to charge individual batteries with very small solar panels? Perhaps extending the battery life and "slowing down" discharge while not in use by slowly keeping them charged and it would select the lowest one for better efficiency or smth. (if possible without changing too much the battery scheme) Any insight into a better solution even? Like adding a solar panel to the "regenerative" braking input? By controller manipulation or smth.

thank you from italy, nobody explained that you had to provide 60mah to balance it!!!!

I had a problem with my diy 10s3p and was wondering why some cells loaded up much quicker and why tha balancing didn’t quite managed to do its job. But with your video I finally got the understanding of the problem! Thanks mate

Pls can I charge 60p 3s 18650 batteries using the bms in this video using a 15v charger? My 45amp mppt solar controller charge my batteries when I set it to 12.6v extremely slowly 1.5a (all settings were correctly done on the controller. And I have 1500w solar panel. But when I set the charge controller to 15v, it charges with up to 12A. My inverter charges batteries with 15v when connected to ac mains. I am scared to connect my battery pack to it. Please help

Correct me if i am wrong, so assuming i have 4 group of cells and i am using a bluetooth bms (ant bms) to charge it all up. So u are saying let's say the cell is not balanced so i have to charge it at probably 2A first and then slowly reducing the charging current to perhaps 0.18A to let it fully charge each cells to 4.2? Am i right? thanks.

HI friend, the led on my bms blink, why ?

Hi.. can we use it for 32650 LFP cells (i.e. 3.21 V 6000 mah)?

interesting basics thanks I guess a 4wire measure of the RI (uner 1Khz) should be added . I have scratched my head a lot with those second hand batteries capacities and processes. In the end what may vary the condition of the LiIon element is his history ; how was it used, charged, at wich temperatures. SO having a balancer module used for the charging may really be advantageous in the long term. If not when we try to recycle a battery that have some smll weakness on one or a few cellules, correctying it with a balancer may be pleasing for the eyes, but it is not a guarantee that the balance will stay in place (on the contrary the weak cells degrade soon, as I was told from experienced friends)

Hey boss! Long time no talk! I'm curious, can I use this bms and charge up to the stated specs. 60amp. I have a 5s3p pack, and typically charge those at 21v 3amps. Will this damage my cells? Sorry, your statement about using 60ma kinda confused me a little. That's way to low of amperage for charging.

Hellooo my old friend.. 😄, you mean 60A charging current? normally charging current is at 40A normal rate, but... if you put some serious heatsinks on the MOSFETs... i think it will work.. about 60ma is equalisation current... if you want to equalise you batteries you need limited current at 60ma..

I like to micro cycle the battery, and charge it with very low current, if it gets out of Ballance, charge at 250ma to 500ma, from about 4v per cell, to 4.25 max, only when balancing, normal use I charge to 4.0-4.1v, or 3.45v to 3.55v with lifepo4 cells, only charging to 3.65-3.75 to balance!
