Hi All,
2018 Mustang GT just recently replaced OEM car battery with a lithium iron phosphate car battery 65Ah with 900CCA.
I have done a BMS reset via forscan and monitoring the battery via nGauge, the voltage fluctuates and with high acceleration above 4500rpm, the voltage can intermittently go as high as 18v which then throws DTC's with error code eg. U3003 'Maximum voltage threshold reached'.
Just wondering if anyone else has experienced this issue and found a fix for it?
Thanks.
