I live full time in my van and need a reliable power supply. Its ironic that the BMS is the one thing that's stopping me switching from AGM to Lithium. I know many people who have lost total power because the BMS has sensed some kind of problem. No warning, no understanding what's happened, just total loss of power. The BMS should send a warning before it just shuts down. Having the risk of a total power failure in my van is not an option.

Is there a specific BMS for each type of battery or will all BMS’ work with any battery?

My DALY BMS 15v 100A Just Flamed Up and Burnt all the Red Wires !

Hi gentlemen...I have 105ah I can uesd 100 bms ? Please if can help me...thank you

[AlexTorres-qvhv]

Have you ever tested the overvoltage cut off threshold of the bms while charging with an mppt CC?
....after being disconnected from the battery by the bms i guess it will ride at the pv ocv...will this high ocv damage the bms at reconnect point??

witch one should i buy for Sonar ( fishing ) I need minimum 28AH LifePO4 Battery ( 5x 3.2v ) i need the smallest possible setup. The sonar use 1ah of energy.

[mikeklungland]

I think I shorted out my bms by disconnecting the balance wires before unplugging it. The voltage now reads 9.5 v with bms connected. Is the bms reparable?

[jregamey]

I wanna upgrade to these. 16 cells 24 volts. How many BMS would I need? And how to monitor every single cell like you have? And bms connects to charger and inverter same point?

[fritz_the_superkraut]

hi chris. great channel. I want to buy 4 x 200Ah cells and set them to 14 volts. how many amps should the BMS have? should i buy the 250Ah version?

[ttttenney]

You state they should never be charged higher than 3.6v per cell, but I thought they were rated at max 3.65v charge rate per cell? Is that not true?

[marcass]

Can I use 48v bmw for 24v battery and just leave the rest of wires?

[HighlineGuitars]

How do you choose the correct BMS amp rating for the battery you intend to build? Is the rating based on how many amps you expect to draw as a maximum or is it determined by the constant and/or maximum current discharge rate of the cells?

[Darkgrin]

Hi
I need your opinion.
I have the same volt and ah bms but it is not written lifepo4 on it.
Nevertheless i tried to use it and if I measure the lifepo4 cells have without bms 12 volts...but if i measure with bms the value shown is 8.6 volt...
Bms is damaged?
Thanks in advance!

How do l know if l need a 100A BMS or a 200A one…..l am new and do not understand

[Veveve]

How do you correctly size a BMS to your things you want to run?

[guyfromboracay]

I have that exact same BMS. Would you know how to reset it? My cells are all reading between 3.31 to 3.33 volts but the BMS itself is only putting out 3.3 volts and won’t accept a charge from my SCC.

[elgringodelasscooters]

Is this lifepo4 bms compatible with lithiun or li-ion batterys?

[sasquatchhuntin]

Do I need a bms on every battery in my system?

[anythinggoesme]

hi, i have the same bms. but when we put the solar and start charging it, we hear the bms producing low humming sound. is it normal? thanks
