this morning I tried to reduce the charging voltage, bringing it from 57.5V to 55.8V, in order to keep the cell voltage lower and not let one of the cells reach 3.63V (as the upper charging limit). In this way from around 97% up to 100% I have a much slower filling, where I suspect the balancer...

Yes.. Here the detalis

I d i didn't update it. It is always the same firmware i recieved and i am not albe to update it.

Consider that I received the cells last week, they are grade A, and they were unbalanced between one and the other by 0.002V, all were specified at 3.25V. What I can do is with the Bmax charge them all to the maximum (one at a time), it will take a long time because they are 105 Ah. So I detach...

Scusate il ritardo e quindi le batterie erano già scariche. you're probably right, it would be better not to look, but I installed the system a week ago and I wanted to check that everything was set correctly. I would add that the functioning of two similar systems seems strange to me...

Thanks so much for your reply. In the last day i have done a deep dive in inside the photovoltaic world understanding MPPT technology. I went to the roof to understand the type of system. My system consists of 8 panels in series and 2 strings. Each panel has a Vcc of 44.14V and an Isc of 5.59A...

Good morning forum, I would like to have your opinion on the behavior of the active balancer that I purchased last week. Let me start by saying that I assembled a 16S pack for home energy storage application, with eve fl105 cells. Daly brand BMS for home battery applications, and a 5A 16S active...

I automated the system by purchasing a timer that interrupts the black cable B0 for 3 minutes every day and then reconnects it. Previously I had discharged all the super capacitors up to 1.5V. In the end nothing changed, when it does important cycles, that is when it starts charging from a...

I also bought 2 versions of this version, honestly the 10A one works much better, when it has no problems.

Good morning, I would like to know if any of you have had the opportunity to implement this functionality, or alternatively it already exists within the BMS but I personally haven't noticed. My idea is to reduce the charging current when the SOC of the battery reaches a certain value. Currently...

Sorry, I wrote the data wrong, it's Voc=44.1V not Vcc because nominally the panels make 185Wp, so with both strings I get a maximum of 2960Wp with Vmpp=35.7V and Impp=5.18A. Today I informed myself even more in depth, and actually the best choice is the multi Rs Solar dual trackers. It gives me...

Sorry i don't understand your reply, did you want to advise me to delve deeper into the reason why the balancer didn't balance well, or to be satisfied with the result? In any case I would like to say that the balancing result is always constant over time but significantly lower than the other...

I reume this post. I am wondering why i followed step by step the tutorial, so i disconnet the black cable, reconnet it, acivated on the app the balance button, but it continues to flash…. Any fedback? I have 3 neey balancers and one time every 6 Welson i need to discarge the super capacitors...

is that delta the same each time you charge? while currently folks are saying no need to top balance with an active balancer i say horse hockey. why not top balance? It simply makes the job of the active balancer easier to begin with.

Good morning dear users, I would like to ask you a doubt. Currently I would like to expand my existing system with an off-grid system, making targeted interventions in several steps. I currently have a 3.2 kW photovoltaic system, to which I would like to add a first self-built storage tank. For...

Good morning boys , i m a new user. In this period i m trying to contsruct a new battery with a new bms. My purpose is to built a 17s 9p with 21700 cells ( samsung 40t ). Now i would have 200 amps for continuous discharge ( 100 amps for channel , infact i have 2 channels ). i'm in trouble with...

I ll use this battery for a e-bike with One 3kw motor and 1.6kw motor.

Yes i buyed this cells on nkon, so i don t have any doubt that are Samsung original with 4 amps

I m here. I take a picture of the balancing. As you could see , I have a good balance but with a low voltage. I started the charging phase but at the end I found a difference higher than 0.14V and then another drain to reset the voltage to a normal state.
