I'm trying to change the chemID on our battery, but I receive an error - 'error code = 1253'. Please advise.

Hi Shemaiah,
What is the configuration of your cells ? Do you have the number of cells configured correctly on the gauge and is each of your cells having a voltage of >3V? Make sure that is the case.
What bqstudio tool are you using and what chem id are you trying to program on the gauge. Also, make sure the gauge is not in a sealed state.

thanks
Onyx

Hello Onyx,

Our configuration is 6p4s. All cells are over 3V. We are trying to change the chemID from our 3550 to 2098. I am trying to change the chemID through the 'chemistry' tab and applying from the database. The gauge is not sealed.

Thanks,

Shemaiah

Hi Onyx,

I unplugged the data cables and the USB cable from the EV2400, closed bqStudio, put everything back together, started bqStudio and it worked.
