I noticed that, seem to be selling a lot of 230ah to 280ah lately, it could be a reason for the reduction of the 100ah cells, The 130ah EVE cells I purchased a while back were reduced considerably.

Actually I'm in the process of calibrating the other meters to match the new unit, although they will drift, especially being hand held units, but at least they will be close enough for most work, and I now have something to calibrate against when needed. Measuring cell voltages will be left to the accurate bench unit.  

I took a few pictures of the final work in progress tidy up.

The cabling to the four battery isolation switches and Fuse blocks is 0G and the Copper Bar is 38mm X 4mm, the switches bolt directly to the copper bar, this allowed a simple compact high current setup with the shortest cable length possible.

The 50mm AC Inverter input cable and 50mm 150A Solar charger cable bolt directly to the copper bar. There is a big cap bank also across that point that still has to be mounted correctly.


Below: Four independent battery bank monitors and the DALY touch LCD display.
The LCD will have a 4 position switch next to it, it will switch data/control between the four BMS UART ports.
