Yes still available.

Thanks guys, will drop the price accordingly.

Still available.

Sold.

@Tim003 didn't receive any other feedback from company or powerforum member. I just dealt with it. Farm we are renting on upgraded to proper system, so the inverter is not needed anymore.

@SEGEN SOLAR any news surrounding this?

Hi @SEGEN SOLAR 92832212100455 Thanks

Hi all, anyone experiencing the Kodak OG3.24 being noisy when grid power is connected? I am not talking about the fans, but I hear a constant buzz from the inverter, almost like being in the bush late afternoon 😀

I understand, will do thanks. Excellent. Yes I am actually building a 24V battery, I said 12V just to keep the drawing simpel, as I am sure the principles remain the same for longer series strings. Yes I guess you get what you pay for. Cycling them once a day every weekday will still get me 7 years of use, so I see it as an okay trade-off for what I pay. Also this is my introduction to DIY battery building, so I can spend R7000 in total with BMS in stead of R23k+ to get my feet wet. I do think in 7 years time, available technology would have changed quite a bit.

https://lithium-cells.co.za/products/55ah-cylindrical-lifepo4-cells Seems each cell can give a max of 1C or 55ah, charge is half of that. Excuse my ignorance, but wouldn't the busbar's resistance cause a voltage drop which would relate to an over/under voltage measurement of that specific cell? Was planning on using the 150A JK BMS, so also planning to switching to 48V at some point, and be able to use the same BMS as it can handle 8-20s and in this way keep the amps running through it well under the 150A limit.

Thanks @DeonBez Busbars are short ones I will be receiving from supplier. Is the above valid for the balance leads of the bms as well? Will a connection to the terminal on one side be sufficient or does it need to be smack bang in the middle between terminals? Also what would be my limit in adding cells in parallel in this way? (Taking into account cell voltage balance and not adding too old and new cells together) The reason for this is I can still have one bms that takes care of all the cells.

Good day all The only lifepo4 cells it seems to be found in the country currently is some 55ah cylindrical cells. I have drawn up a picture of a 12V, 110ah battery bank by connecting the cells first in parallel and then in series. My question is, would it matter if the adjoining modules are connected via busbar on only one side as in the picture? Should it rather be connected on both negative terminals to both positive terminals of the next module, or should I drill a hole in the middle of the busbar to try to keep resistance the same to each terminal?
