They had mine out for delivery on Monday and tracking showed them on the way to the depot. Then the driver turned up!! She said they had been offloaded straight from the delivery lorry straight into her van so weren't scanned into the depot.

It will be a while before I get them installed, just moving them a very shot distance wore me out due to the Long Covid. (I started taking a product called Nattokinase, after lots of research, (blood thinner and clot buster) about a month ago and thankfully I now recover from the fatigue much quicker and my head feels more normal).

I caught it Feb 2020, it was only very very mild for me but it killed my mother. I seemed ok ( looking back I did have some symptoms) until July 2020 when my heart rate went up to 225 and I went into VT. After an MRI I was diagnosed with viral myocarditis. Since then I've had fatigue- just like hitting a brick wall. First time it hit I'd only walked about 200m and I honestly didn't think I would make it back to the house. Headaches for months on end, balance problems, really weird vision problems, breathlessness, head pressure, pins and needles, muscle aches, really loud tinnitus and other really weird things. I was the person that was always active, fit and never used to catch anything. If I hadn't suffered from LC myself I really wouldn't have believed what it can do. I'm lucky though many previously fit people are now confined to bed.

It seems to get people in many different ways and symptoms can change from hr to hour.

My cells arrived yesterday, they were originally scheduled for Monday according to DPD but it might have been a similar situation to Tinbum.

Well packaged and including the BMS I also ordered (for a very good price compared to some suppliers).
Hoping to find time around work to get them hooked up this week.

Thanks for the good service and great communication Colin!

Some progress made today - battery storage and clamping system built and installed.
I'll be getting the DC cable, lugs and a crimping tool ordered today then I should be able to get it all wired up.
Simple OSB box, bolted to the wall with two supports for belts and braces.

All the material was left over from other projects, OSB might not be as attractive as plywood but I'm not going to break into a full sheet just for this.
Once I'm finished up, I plan to put a cover of some sort over the front. Shame I don't have a length of plexiglass or similar.
