Performing a capacity test on first set of four 100 Amp Hour cells using my old stand-alone tester. It can only draw about 13 Amps. Will also test them again with my 100 Amp shunt to see if the two are close to the same result. Will be able to draw a proper .2C (20 Amps) with the shunt. Will use my new 600 watt inverter and a 200 watt ceramic heater for the load.
