Hello
I have just installed a 100 amp 36 volt lithium battery to power my MinnKota electric motor on my boat.
Until then I used 3 12 volt batteries and I controlled the charge and discharge parameters on my Victron BMV700 monitor
Since this new battery is in place it is impossible for me to get a reading on my monitor, it does not work.
I checked my connections, my monitor, I tried another shunt without obtaining any results.
Thank you for your help
Have you used a volt meter on the battery? Some of the newer smart lithium batteries need to be “activated” to get them out of shelf mode. The Renogy batteries have a button that needs to be held down, for example.
Thanks
Indeed I have to activate the battery via the battery’s Bluetooth application to obtain the voltage with my voltmeter but even in this situation the BMV does not work
I also tried a new shunt without result, I think that the BMS is responsible for the problem and cuts the power to the shunt
