I'm just wondering;Burgerman wrote:Well you already know lots, so its easy for you.
Go to http://www.evassemble.com or wherever you choose and for group 24 replacement order 72x 12Ah headway cells. And 72 orange blocks (included), and enough bus bars. (13 x 6 x 2 + 26 on my 78 cell pack). You will need to work out how many...
Then charge every single cell to 3.600 volts, and leave on charge afterwards for 2 hours minimum to soak. You can do this in parallel in big groups of say 10 at a time. Will take about 2 days. Then put them all in a box, disconnected and loose and forget them for 2 weeks or preferably more. Now charge each one individually (will take just a few mins) and write capacity added in Ma at the charged point in software on each cell in pen or on a sticker. This is a measure of self discharge. How much it lost over time in storage.
When you have done this you need to put them in groups of 9 (each parallel group) that add up to the same Ah lost when averaged. So all the parallel groups are as similar as possible when added up. You will have 8 bags/ boxes with 9 cells in each with similar average self discharge levels.
When you get this far email me or post here! I may have a page up by then.
This is for group 24.
For group 34 it doesent work out well, and is an awkward configuration. With 56x 12 Ah cells. Thats 28 per block but it can still be done.
For 22nf it can also still be done with less 10 Ah cells but ends up with each pack about 12mm wider. This may or may not matter. A tape measure will tell you.
I will also equip it with lithium batteries
What you're talking is giberish to me, because I know bollox about electricity
