in my group we are waiting to receive about 500 cells among the colleagues, when they arrive we will do tests to see the capacity, I have the checker EBC-A40L, I'll give you the results

since now they are talking about these cells lishen I add this photo, provided by basen.

Give me a few months and I'll tell you how they're doing, and a few years to really find out ...

do you have any dc dc to charge from the alternator?

it does not matter if you use a power supply or a charger that is capable of giving 200a, when the voltage is close to the established one the amps will go down, and it stays like this for many hours, according to what they say in the forum we would be damaging the cells.

https://ibb.co/LzXH92j yes, are fuses, here is the link to image for more detail. thanks.

I think now I understand it, you have to put 15300 or 65535 in seconds, but keep using the code 123456 to validate the changes. I thought you had to put a different code than 123456 for that.

I have two firmware, one for bt work and one for lcd work, I have tried both and they both work, I can put one or the other without a problem, if you want I can give them to you, but I am not responsible for what may happen. ;)

If you see the video of the 280ah article, it tells you that it is 272 lishen, but that capacities of up to 285ah have been verified in them, I think that having duplicate ads helps them to attract more customers, because it is easier for someone to search for 280 than 272.

I did not think to buy there, I am only giving the information I have about the supposed 300ah cells in that company, because I have not seen another that offers them, to try to clarify what cells they really are.

Thanks for your answer, I am the founder of a new DIY group in Spain and we are planning a joint purchase from Basen, to buy about 150/200 units, and we are very undecided if it is worth paying $ 4 more for EVEs. In reality we are not concerned with the capacity, if it is 272 or 280ah in the...

for that I will have to buy it first, and that's what I don't want to do hahaha

I would trust jk more than heltec, since jk is the real manufacturer. heltec is just a rebranding...

Hello, I am about to buy 280ah cells, but I can't decide if it would be better to buy EVE or LISHEN, from everything I have read in the forum it seems that EVE is the king of purchases here, but there are also people who have bought LISHEN and there are no negative comments about them, the...

I'm sorry, the translator has played a trick on me and I have published in Spanish when I wanted to have do in English, I have already edited it in the main post. I see that there is not much history of lishen in the forum, so I appeal to whoever has them, it would be good to know how they go...

hello, this is very interesting, unfortunately I don't know how to handle it, but I'm going to send this information to some friends, have you got any progress?

How many amps should I put in? I had thought about this one, which has a lot of sales with very good variances. € 6.24 | 2P DC 1000V Mini Solar Circuit Breaker, 3A 6A 10A 16A 20A 32A 40A 50A 63A DC Switch with MCB for PV System https://a.aliexpress.com/_B1Mnf0

I have gotten these images of the Daly 4s 200a pcb, I confirm that by putting a switch on the two-pin port (key + gnd) you can activate the bms and activate the bluetooth when you are sleeping, in this way you do not have to leave the bluetooth always on.

I thought this balancer was better, which one do you recommend quality / price? I only need for 4 cells and the active balancer of jk costs about 100eur, it is expensive for only 4 cells, if I had a bank of 16 or more cells it would be profitable. but it hurts to pay the same for the same device...

I was thinking about what you are commenting on and it has occurred to me to think, if so much power is needed, how is a small battery capable of starting a vehicle like the ones sold now? like this:

I am preparing the electrical installation for my camper van, I have created my first installation diagram, I would appreciate your opinions about it. The fact of putting a dcdc and mptt to charge from the alternator is because I already have those devices, so if that works it could save me...

Estoy algo confundido con esta información, ¿es posible que sea algo antiguo? y que el nuevo bms de puerto separado puede manejar 40/50 amperios a través del puerto de carga? I am somewhat confused with this information, is it possible that it is something old? and that the new separate port...

Could someone explain to me what exactly this device does? what is inside and if you could make one DIY at home.

my 4s 200a bms does not have the same connector arrangement. nor does it have any character in Chinese. maybe you can use an ocr translator to know what it says there. What I would do is ask daly about this though.

What I want to know is that it has exactly that inside, it is probably not more than 4 components that are worth little money, my question is if anyone knows what its internal functioning is, to see if I could emulate it.

I bought this balancer after watching this video, I will do the test as it only cost me 10eur, I hope it is not really necessary to use a balancer, and that my cells do not become too unbalanced.

Yes, it is already solved and I can communicate with the pc, it was a configuration problem. Now I have another problem, they have provided me with a new firmware to operate the LCD and the monitor port at the same time, and I can see and configure all the parameters from the pc perfectly. The...

this is mi solar panel, Is the circuit breaker that I should put according to those amps? 10a seem few, 16 many? for the other side I will take the 32, because since it is not inclined, I do not think that the 100% plate will ever be. Should I put another one between the dcdc charguer and the bms?
