HK, Merci. I might be okay, after grief.
What I did, briefly, ignorant dude I am, is mess with product that failed, with one set. O had to redo non-weld packs and got another set of cells, the 30Qa.
Made another pack and it ran for a a very short bit and quit, (BMS) shut it, after this bunch screwed me and had a small fire with first batch...no parts. So, had the Panesonics and cobbled another pack, which is the one that failed on the road. Both sets of cells, 30
Qs and Pani PFs all match etc (out in garage til later).
I was so pissed at Av and spent so much time and money, I bought ready-made from Amazon...runs fine, so far.
I plan to take two pack out each ride...one to play; one to get up hill. Taking the ready-made for hill climb home.
At this point at noon will recheck voltage on cells and if all are 6-7.1 will assemble in NESE modules, connect the BMS and ride.
Sound like a plan?
I should note, was advised to set 6.5v as magical ideal for storage, then charge in close-sets...so BMS, finds easier balance of each group (is a 10S 4P pack) Was also told that tenths of volt differences are neglisable i.e. 6.9 or 7.1 in pack as BMS will balance...
I know this is basic stuff, but picky....have done 4 gas rigs and all 4 as group were easier than this one venture...FWIW, but figure to win at any rate...I tend to do decent work but am scared of these cells, after one fire and so on.
Here is pic of first 4cycle rig...
And pic of current Swift Zootr, before geared hub/controller added. Pack hangs from bars in small bag...spare in back; so you have idea...!
Next rig on a Rans Dynamik...if I can get it together...
