Was the 1.5k resistors. Changed to 470 and the signal edges improved. I'm assuming this is because I'm using the OEM transformers and must be slightly different. Thanks

Re: Ranger rover 14.7kwh pack bms
Hi there,
I have managed to get comms with these using Bexander's Arduino firmware which I modified to suit the 12cell pack. I haven't looked at balancing yet but know the pin outs, got the setup sorted and receiving all cell voltages.
Happy to share info if anyone needs it.

Re: Kia Niro BMS
All working now so thanks for the information. Got Comms with one module with 12 cells so will just tweak for the six modules when I've added what I need. Voltages read through ok so very happy.

Re: Kia Niro BMS
What step of the initialisation is failing? Have you made the correct adjustments to the SW to use only one slave? Is the slave wired correctly? Thanks for getting back to me. The chain initialisation failed, however I scoped the signal at the Rx of the IC and it was a distorted triangle wave. I'm ...

Re: Kia Niro BMS
Hi there, Firstly many thanks for the information and code posted here. This has allowed me to progress a long way already towards using the MAX17841b IC. I am working on a communication interface so I can get the BMS data from a bank of 6 Land Rover Samsung SDA modules which use this interface. I h...
