Lithium batteries and microwave use
I am considering replacing four GC2 batteries with two 100 Ah LiFePo batteries with 100 Amp BMS each. My concern is whether they will be able to operate the microwave for light duty use (5-6 minutes) ...

I’ll make my question a bit clearer.
When I designed and installed my system 12 years ago, lithium was still a dream for RVs. The battery discussions revolved around whether it was best to use a 12-volt battery or multiples of them, 6-volt batteries in series, or break the bank and go with AGM.
At the time, most agreed that a pair of GC2s in series were marginal to operate a microwave. That convinced me to go with four GC2s (440 Ah).
My specific question is, are the characteristics of lithium batteries sufficiently different from FLAs that 200 Amp hours of lithium batteries with at least a 200 amp BMS will operate the microwave without voltage sag causing inverter under-volt alarm or shutdown?
Should be, is not a helpful answer.
