I haven't posted in a while (sorry about that) had a bit of a knee issue, this delayed my progress somewhat. All sorted and back at it now.
I have had a bit of a rethink about the electrical system, i was going to go with 10 x AGM batteries, specifically Victron 200Ah ones, having given serious thought to it, i have changed my mind.
The new plan is 5x Victron Lithium-ion HE 24v 200Ah Batteries, not cheap but seriously good. These will be managed by the Victron 1000A Lynx ion BMS unit. and controlled by the Colour Control CCGX.
Total Batterie power 25KWh.
Here is a few of them on the test bench:
