No it isnt. Cy can give more detail. But if a lithium iron phosphate battery gets below about 10 volts at any stage it's not possible to recharge it properly using the alternator. It will only take a tiny charge unless it is properly restored using a special charger and cell balancer
Mine went down to 6 volts after an 'incident'
