@Louisvdw I created a python app that logs from the JDB via bluetooth using gatt, works perfectly but I hadn't been able to extend it to add the battery on Venus OS because it only has python 2.7. Do you intend to implement an option for a bluetooth connection?

Thanks for the quick response! Yep, I have a BMS that disconnects the battery when a cell reaches 3.65V. Does this mean I’d be better off using the Lead Acid setting? That’s good to hear. Can the charge controller be damaged by the lithium cell being disconnected while charging?

My brother is looking to get a drop in lithium pack for his van, has anybody got experience with the NYDPP 250Ah 12V LiFePo4 Battery Pack on AliExpress? https://www.aliexpress.com/item/4001313193451.html?spm=2114.12010612.8148356.2.252d33b4OWhKid

Just a quick one as I can’t find this info anywhere. On the Xiaoxiang BMS iOS app there is a configuration setting for ‘Delta to balance’, what is this for? Is it the minimum delta before the balancing will take place?

Great, thanks for your quick response. Currently I have one cell lower than the others and I obviously need to do a top balance with a DC power supply, however I live on a boat and that’s quite a bit harder to do especially with the lockdown in place in the UK. My charge controllers are holding...

I have an EPSolar Tracer that was used to charge house lead acid batteries, however I’m in the process of hooking up my lithium battery and I’m not sure if I need to get a new charge controller. The tracer has three battery options: 1. Gel 2. Sealed 3. Flooded It has no option for lithium due...

I've ended the auction but the cabinet is still available

I have a Fogstar Energy server rack cabinet with large bus bars installed that is surplus to requirements, these retail for £599.99. My price is £400 plus shipping, happy to take offers. https://www.ebay.co.uk/itm/305608433627 Specs here...

This occurred last night, any ideas why? 12V DC system with JBD BMS and 190AH battery

What would your recommendations be for this driver and the JDB BMS?

Excellent news! If you want a hand with anything please let me know, I’d be happy to contribute. Python 3 would be a dream, I hope they include it soon. I’m aware that I could use the bluez dbus api with 2.7, I did a bit more exploration on that last night and I’ll see if I have time over the...
