Great thanks!

Problem is supplier no longer exists

A friend has lost his JK BMS software to change settings as well as getting into the device. I have heard about this special code valid for 15 minutes - who do you contact for it ? Is it the same for all or is the code different for every BMS. Could someone perhaps share the code privately to try

I also have a ZeTech and was also considering a testing methodology to apply over the lifetime of the cells ( annually probably ) and was considering charging to 3.425 V - perhaps even a cut-off of 0.01C and discharge at 0.125 C to 2.8V. Question I have is how do you program the ZKetech to...

Thanks ,

I going to build my 5th battery which will be a 16S2P battery and I wish to pair the cells according to some methodology . I do have the ZKeteck battery tester and will test all cells for capacity and IR . Option 1: Match pairs of cells with the closest Capacity ratings or Option 2: Match...

Has anyone tried out the SVOLT 184 AH blade cell ? I'm keen to find an actual discharge curve in order to determine if they will share current proportially with a conventional rectangular cell . Their chemistry must be slightly different as they can be charged down to -20 degC ( -4F ) and safe...

The Apple app store lists 4.9.10 as "add some functions " . Has anyone found any new features with this version?

This is all you need

copy other peoples code refer to this channel and more specically this video

you can use rasbery pi. I already have a cerbo as its part of a Victron system

I have a different solution - I am using dbus serial driver ( https://github.com/Louisvdw/dbus-serialbattery ) which is running on a Victron Cerbo . With this I can monitor all the cell voltages via Internet , just cannot issue any commands.

For Louis - when can we expect the next official release of the dbus driver ? the excitement is building up

No

I note you mention 2 cycles for the JK to adequately calculate SOC - now you say at least got down to 25-30%? I have one that went down once to 6% ( doing a battery capacity test ) and it seems OK, my other two have never been below 70% and they are hopeless. I want to try and improve them by...

What do they mean by switching ? Is that switching from one BMS to another ?

HAve not tried 4.8.5 yet , current on 4.7.7 - any new features ( Android )

Has anyone tried v4.8.4 , now out has this bug been sorted ,

Version 150A

Version 200A

Log for the 150AH , note errors are all from over 2 weeks ago and was due to setting changes ,

LOG for the 200AH

I have a come across a suppler for REPT 230AH cells locally however my concern is that QR code does not compute . It comms with labels indicating actually measured capacity and date of measurement . Are there differing QR coding methods? Do I need to be concerned ? Do I need to be concerned ?

Russian decoded by google

Does anyone know what the maximum allowable battery voltage is to make an internal resistance measurement of ? The unit can measure 99V DC in DC voltage mode however in one unofficial manaual I see a reference of max 28V DC for IR measurements and another Russian manual refers to a "buffering "...

Check against what ? Is there a firmware changelog register available somewhere ?

Nothing logged

HAve 3 batteries in parallel and usually discharge from 100% SOC ( according to well calibrated Victron BMV ) to around 70% overnight then recharge . One JK battery has the 200A JK and that is always within 1 - 2% of the Victron reading whilst the other two - both 150A JK's show correct...

Thanks, does anyone know of an extender that will support this standard

Can anyone recommend a Bluetooth range extender for the JK bms ? Currently all the extenders cater for audio data and don't know if they will work with the JK BMS

CAn you make cell IR measurements with YR1035 of a cell in an existing battery - ie (1) all wired up and (2) when connected to to charger / or inverter. It should be able to as it has a very narrow 1 kHZ bandbass filter I 'm sure.

Thanks Steve , yes I am using 3.425V and often do not charge to that as it depends on Solar and my 3 day solar outlook. - if solar looks good for the next 3 days I do not charge to "100 % " often to only 70- 80%SOC - so not sure if JK proprietary algorithms will handle that

What algorithm does JK use to determine 100% SOC , there are various ways implemented out in the battery world and they all must include a "reset " as couloub counters will eventually drift to a point of not being usable - Victron use a both a voltage and threshold current , I cannot fathom out...
