Thanks for that, I have contacted the guy that supplied me with the cells to see if he has enough to complete my wall,
What would you suggest as an appropriate range for IR ,? not many of my other cells read as low as the 30 ohms
Also, thank you for the recommendation on the YR1035 from a...
I have been collecting and testing cells to make a 7s 60p , By Capacity testing they are all between 2200mah to 2400mah.
A large percentage of my cells are
I have found a spec sheet for the H18650CIL which states the IR as ≤50 I have IR tested about half of them and they are coming out at...
I've recently installed Venus Os Large on a raspberry pi to read a Victron blue solar 75/15 MPPT, the powerwall is a 7s30p that I put together a couple of years ago with new samsung cells. I have a JBD 60A BMS so i have been able to monitor the packs on my android tablet.
Now that i can access...
I am in the process of capacity testing secondlife cells for a 7s60p with an Opus BT-C3100. (and another on the way)
I understand that the Opus can be a bit off when it comes to IR testing, but by how much? and what sort of figures would be acceptable using an Opus for IR readings?
@sshoecraft thank for all your help,
I have connected to the BMS using Jbdtool through serial port.
$ jbdtool -t serial:/dev/ttyUSB0,9600 Battery
gives me a full read out of BMS,, all good
I have read a couple of tutorials and followed these instructions
$ sudo nano...
Wow thats something to work towards,
I have alot of questions but i will try an keep it short,
I am currently running the static version for pi that you put together, do i need to switch to the github repo?
I was so pleased to finally make contact with my BMS and start pulling data from it. thank you @sshoecraft et @Delta-9 for your help.
Now im looking at how to use that data, I obviously have alot to learn so i thought i would ask you guys if what i am trying to do would be possible.
Thanks guys, I am trying to understand all the info you have given, thank you
So I am leaving MrSurley's bms tools until i have a bigger SD card, thank you Delta-9 for your suggestions
This morning i have gone back to Sshoecrafts Jbdtool
Thank you for the raspi version. I have downloaded the...
So i have been trying to install and run MrSurley's BMS tools on my raspberry pi. Thought it would be a good chance to learn a bit.
It took all my available time yesterday to install the following,
Pip 21 (tried pip3 but no luck)
I've had numerous failed attempts at installing...
Thats great, I've just dug out the UART connection that came with the BMS and im ready to load up your JBD tools,, I 'm just learning (not very fast) how to install and run programs on the PI so it may take me a few trys but at least i know it can be done. A more attainable goal than my other...
I have a XiaoXiang BMS , I have been accessing it from my android tablet bit hard to connect sometimes, but great to see whats going on,
but would be so much better to read it through my raspberry pi. I have Ubuntu/linux machines so have never used the existing windows program.
What do i need...
I'm going to try a larger capacitor on the input of the converter see how that goes, i tried a 100uF no better results but it didn't make the ticking noise,,
for the Amps drawn on start up of the pump i have an inline watt meter not sure if its good enough to measure any spikes, but i'll give...
I get your point, but i think we are at crossed threads,
I'm trying to connect a 24V DC/DC 12v converter to the load output of the MPPT.
I have a 24v charge/battery setup and want to run existing 12v pumps etc through the load of the MPPT so i can read my consumption with its software.
i put together the following with caps i found around,, but not sure if the first cap is suitable
in parallel to input of converter - 2.6uF 400v 50-60 Hz
sure its AC an im using DC,, but it is from a water pump,,,
in parallel to output of converter - 100uF 25v DC
I test drove it on a 19.5v...
