Hi All,
I've had a 18650 power wall running for 3 years.
I've not had any issues which any of the packs but noticed recently on a night charge on the cheap off peak. One of my pack is cooling when charging.
I wonder if this Pack is suffering from some kind of strange exothermic type...
Hi,
Thank you for your replied. Much appreciated.
Functional description of my shed system is I have an 400W solar array connected to a Victron MPPT Solar Charge Controller. Connected to the dc bus is a 3KWh 7S 24V lion battery pack. An adjustable 500W inverter and 30A charger. I only use this...
@SeaGal unforunately I cant. I bought aload of those 18650 pcb boards. I did have a look into how I could split each pcb trcks to make 2 x 7S but its impossible.
@DIYrich I use node to control how much I charge and discharge to my house depending on house load, solar generation and cheap off...
Hi All,
I have a 48V 18650 6kwh battery running for the last 3 years in my garage. Ive recently upgrded them to Lifep04 cells for safety reasons (dont want lion in the house anymore).
I want to couple up the 48V 18650 6kwh battery with my shed solar install but my battery voltage is 24Vdc...
Hi Nigel,
Funny timings. I yesterday fitted one. Along with some nice Victron Mega fuses. Confirm JKbms Shunt is pants.
In with the victron smart shunt.
Cheers
Hi All,
Thanks for your replies.
I think your right the JKBMS SOC is not accurate. I understand that the SOC cannot be accurately cross referenced with the cell or bank voltage due to the flat discharge/charge curve. This links were a good read :)
Im running the venus OS drive for serial...
Hi All,
Ive recently built a DIY 280Ah Lifep04 24V battery managed using a JK BMS. Last couple of days my bank reached the low cell voltage cutoff of 2.6v and reset the SOC to 0%. Then at 00:30 the cheap off peak leccy tarrif that im on. It kicked in so it started a night charge for 20 mins and...
Hi,
You don't load it into influx. The getbms-ant.txt is the instructions of how to set this up from start to finish.
What stage are you at now? Do you have a SD card flashed and rasbrian up running?
Cheers
Hi Jon,
Start by flashing a SD card with the latest version of raspbrian here. Im running it on a Pi4 with a 32GB sd card.

Then enable SSH in the settings.
I use Putty to connect to the Pi.
Then use the getbms-ant.txt file to load in...
Hi,
Thank you for your reply :)
Your code didnt quite work but certainly pointed me in the right direction.
This code below works. Thought I would share this if any one else has want to do the same. As everyone probaly knows that the balance current is not much and only enables when...
