This morning all 10 of the batteries were completely charged up, I have on order a dual voltmeter and ammeter (voltage and current measurement on the same display) so I can keep an eye on both current draw and battery state at the same time.
The batteries will be going in the unit shortly so tests can begin to make sure it will handle various loads, specifically CB radios and, for power cuts at home, phone chargers, also to see what voltage these particular batteries really show on the output (they are Maplin 2400mAh rechargables), some batteries may show 1.25 V at the terminals, that's about 12.5V for 10 batteries, some may show 1.3 at a full charge but this could be very rare (it would give 13V). During the tests a basic multimeter is to be wired across the terninals to check voltage.
So I shall get on with that and report back later
