I picked one with an LED so that I can see it is doing something as some of them have no indicator (although probably won't be able to see that when it is packaged in the van).. Haven't tried it yet though so can't give any feedback on whether it is OK. From first look the leads are a bit short...

Yep... I followed the "Step and pause" process in the document "Top Balancing LiFePo4 Cells using a low cost benchtop power supply" from the resources going to 3.60V. Just recharging the pack and waiting to see if the cells do come out together. Having read elsewhere that cells that aren't...

Has taken me a while but finally managed a capacity test for my assembled pack - 8S 24V CATL 310Ah using an inverter and a 300w lamp. I only tested down to lowest cell hitting 2.5V and the Victron shunt I have recorded 296Ah so less than 310 advertised but not as bad as some of the figures...

Copper braid with copper pipe flattened over it and soldered/drilled...there are some examples on the forum if you search for braid and/or flexible busbars...

I haven't and didn't plan to as I didn't have a capacity tester originally... however have buckled and ordered one from Aliexpress which should be here in the next week or so will try doing some then although it is only one of the 180W ones so may take a while.. I have a Smart BMS on order as...

Remainder of photos. The last photo is the tracking label. The number ringed is the DPD number you need to enter (assuming parcel is coming DPD)

So feel for all of you in the States whose batteries have problems but my 8 cells have just arrived in the UK thankfully OK. They are packaged exactly the same. 2 boxes, each with 4 cells per box. Each box had a base with separators but at the top just a slab of foam. The terminals have poked...

?? That is why I paid goods and services?? :confused::confused: If there is a problem you have 180 days to file a dispute hence my November date and no concern at present (other than dreading what will turn up)..... just pointing out that Micheal wasn't forcing Friends and family.... it may have...

When I paid (in May) there was the option to pay friends & family or as goods & services... as long as I covered the PayPal fees... Michael was easy with whichever way.... I went for goods and services so have paid extra and have until November... sitting tight for the moment to see what turns...

And what size were the cells?? I think there 4 different sizes... 271,280, 302 and 310 and not sure if all sizes have been placed with the same supplier or perhaps different ones as has been hinted so knowing sizes may help work out who is badly packaging? So far I think it is the 271 ones...
