As an ALTERNATIVE:
So snowchyld, you were saying to maybe I can series up the left side and series up the right side. And then parallel them? This way I can keep all the wires in the same position even when I bulk charge? ..Let me know if I got this correct.
I can see how this can be messed up since this isnt the normal routine of plugging in the connectors. I wonder if I can make a bullet & wire housing of some sort, maybe something out of wood, so all I have to do is connect blocks together (one side has the bullets, other side has the loops of wires set up in series) on each side of the bike. Anyone have any experience with this?
doc007 wrote:Snowchyld, thanks for the info!! It's a lot clearer now. I think I will use your method of wiring since I do intend to bulk charge. Also, there is less of a wiring mess.
1) When I wire up the batteries like you have in your drawing, do I need to worry about the order in which I connect them? I was thinking of making a block of bullet connectors that plug into each side of the pack(20s1p) at the same time.
2) Also, do you think I will have to worry about a spark when plugging them into the controller or the charger?
Thanks a bunch for all the help!

one thing that is not clear is about the balancing wires :
here we have 10 battery packs , but only 5 exit for balancing ?
how can this be ?
when you want to recharge all packs , you must break up the wiring and ri fix them later .
is there no way to to bulk charge them all together .
ps I am using LIPO 6s 5ah
1) What are the pro's and con's of permanently paralleling? Anything I need to worry about? Anything I'm missing?
2) Essentially I will have to join two wires together and make it lead to one. What's a good way to parallel each pair of packs for a good/clean/strong/reliable connection?

[dont be so sure lol ive never played with RC stuff before so this is all new territory for me] As long as you realize permanent connections would make it much harder to remove the brick and place on a conventional RC Balance charger I see no major drawback from permanent connections. In fact, fewer connections usually better for any high power circuit.
It's been well over a year since I've broken series groups up and all my power connections are pretty much locked together. I've brought up a few low cells over that time but just by using the balance connector and charging 1S directly to the low SOC cell.

pro: no connectors, easy, no chance to connect them reversed
contra: if one of the paralleled cells is damaged, you won't realise that, or better said: as soon as you realise the broken cell could have damaged the good one as well
solder two 14awg wires directly to the connector. or open the insulation of one wire at a length of 1cm, then remove 1cm of insulation of the second wire, put this wire next to the now clean wire, and wrap some centimeters of single wire (eg. cat5 cable) around the two wires. that way they won't move when you solder them together. then put some heat shrink over the wire for insulation.
rem: use the BIGGEST soldering iron you can find. 80w+ is good. the longer you put heat on the connection the worse. if you put too much heat into it, solder win run inside the cable and make it stiff.

Also, where were you getting your 4V source from? and how were you monitoring it to make sure you didn't over charge?
