763 b2.2 battery voltage warning

[BC4420]

My bobcat is showing the b2.2 error code and beeps 3 times in a row continuously. It starts with no hesitation but will shut itself off after approximately 10-15 min while idling. Everything functions properly while running except for the loud beeping in the cab. On the led upper right hand corner the battery image is blinking and shows one bar. I have replaced the battery with a new Bobcat battery, replaced with new positive and negative Battery cables and new fuses and a new alternator. The meter shows 14.6 volts while running at the battery. Any other possible fix suggestions are welcome. I unfortunately live 3 hrs from a dealer and they have quoted me $475 to pick it up and same for return, then whatever else for diagnostics and repair.

at 14.6 volts that is just where it should be at the battery, my only suggestion is to get a voltage reading near where the panel looks at the voltage value (you will need to get that info) to determine which way the fault is ,make sure to check your grounds ,sometimes they get overlooked but are very much a part of the circuit.
