Woaw....looked up at megacell charger on the web.
Are you happy with it ? How accurate is it ?
And could you give us the size of the board ? (Lengh / width ?)
Thanks in advance.....Happy new year....and congrats on your powerwall. Very clean install.
Not sure it is a safe way to go.
48V converter efficiency is not that bad. And I am not sure you will achieve a better efficiency with a dc to ac inverter.
You probably will be better of with a 15S40P battery.
Just my 2 cents.
just a quick question....
I am going to put 20 x TP4056 on a board to charge my cells (Like many of you did)
I will use a computer PSU to provide the 5V required.
Now, to provide the 5V could you tell witch configuration will be suited best ?
I was thinking, maybe the loop will...
Sh*t.... I hate to say it, but you beat me on the line here. :dodgy:
I had the same idea and project is under construction....a new thread will be online in 2 or 3 weeks.
But congrats, it really looks nice and It seems really practical.
Ok, my bad....the icon set you on the wrong foot. Power comes from the grid but there is a Apple Mac Pro Power Supply between the grid plug and the MPPT :P
But thanks for the warning....and your answer.
I don't know why but I wasafraid the junction between both batteries, MPPT and converter on...
Thanks all for your answers.
I will probably upgrade the MPT Fan at first and in the near future change some condos like theses guys=>http://vae-tech.forumactif.org/t111-regulateur-mpp-universel
Also, will this work ? (The Xt60 double double connectors between batteries and the other stuff?)
I just bought one unit of the MPT-7210A, and I don't find answer to my question on the constructor documentation and neither on internet.
Could someone help me out ?
1- What is the maximum amperage for the input ? I will be using a beefy pc PSU and don't want to kill the MPPT (PSU could...
like many of you, I am building a charging rig to be able to process quickly my batteries.
I went for the TEC4056, which are based on TP4056.
Now my problem/question: I want to solder the charging cable (not gonna use the usb port) but I don't find the in+ in- like on the...
