I found out today why the secondhand cells that I bought only had 1/2 capacity of their supposed

Many thanks for the detailed reply and info. Yes, I was aware of the internal heat soak being the key

Ah, now I see you can't have a negative load current :) On Monday, December 22, 2025 at 12:59:06

Full sun today and also the shortest day of the year (technically the shortest is tomorrow but no

It is almost identical other than the IO5 and IO6 that where moved. On Saturday, December 13, 2025 at

Battery heating should be done by an external thermostat. I think a digital thermostat is maybe 10 to

Yes that is similar to the inverter's I use. But it will work just as an inverter not the other

This sort of cells have fairly low internal impedance so the busbars and connections can add some

Very looking forward to this. Thank you. On Sunday, November 23, 2025 at 6:48:33 PM UTC-8 electr...@

Yeah, $6 is totally reasonable. On Saturday, November 22, 2025 at 3:49:14 PM UTC-8 electr...@gmail.

The fuse seems fine but that 63ohm seems to not be useful as it is not looking like a short so

The cable requirement will be the same for positive and negative. If your panel is 15m from battery

You can also connect NTC thermistors 10K B3950 instead of 10kOhm resistors. The DMPPT450 without the

Thanks for the replies. The model I have is an MPB 1200-12. Yesterday I had the generator running and

Xavier, Your battery is fully discharged not just that one cell. The photo's you provided show a

Have you removed the red jumpers from your optoisolator board ? You mentioned that red LED is not ON

I took a few screenshots from my setup so you can compare. This is from today on my setup with 560Ah

So from the adapter project I learned, that you can also access the serial port by using /dev/serial/

Just letting you know, that I have added support for the serial Port / USB Connection. So you can

You do not need to set a max PVOUT current since most likely you are not using a dual PV array.

Yes you can have multiple EXT IOx set the same type. On Monday, September 29, 2025 at 12:37:17 AM UTC

Paul, I have the Victron BlueSolar MPPT 100/50 https://groups.google.com/g/electrodacus/c/cmLykQadmUk

Based on what you say the inverter was still working while SBMS0 LCD was white. If inverter was

Yes you need to disconnect and reconnect the 12 pin ribbon cable and screen should look normal. There

Using all 3 solar panels means 24 to 26A so you should look for a 24V 600W heating element like this

John. I had the same problem trying to get .5mm ferrules into the SBMS0 connector. After the problem

First test to se those devices work (turn OFF) by just removing the EXT IO4- and EXT IO3- from them

Jim, Yes if the battery temperature gets back to normal temperature the charging and discharging will

When you power the SBMS0 initially the SBMS0 shown will be 49% and at full charge it will be reset to

Anže, There is no setting for round trip efficiency in the SBMS. I can implement that in a future
