I don't have any Chinese cells, I have some Edison's, I run 12 of them to run a cheap 700watt MS inverter, 1.2volts X 12= 14.4volts, abit on the high side, I can't charge and run the inverter at the same time, overvolts, charge is about 1.6 volts, so about 19.6 volts, to high for the inverter,
NiFe batteries are not high discharge, so 100 hour rate works best for them, if you need 500 amps, you want ones that have 500 amps for 100 hours, they have a very bad voltage sag. If you use them for motive power that is not quite as bad as with inverters that shut down for low volts.
