Hi Spec, did some more tests on it, I connected the extra battery to give me 4 in total and connected the transformer via the bridge rectifier on its own with out the capacitor, and here are the results:
DC V across the end terminal posts gave me 53.2V at the start which rose to 53.90V after 25 minutes of run time (13.375 V/battery). V at the 3rd battery went from 40.1 to 40.5V this is without any load on the batteries and the temp of the transformer frame went from 33C to 38C in an ambient of 26C air temp.
So now I need to find something that will suck out 40A @ 36V out of the 3 batteries and then measure the voltages. So overall I don't think that it is too bad assuming that the 100Hz rate of the charging voltage won't interfere with anything on the heater module or the extra 0.5V, which I can't test for a while till I repair the module.
I already have a 32A circuit breaker installed but will swap that to a 40A when I get one, I know I have one some where in the shed but finding it could be a bit of an issue.
