yes. There is a line to each subpack. The wires are #22 so there is no need for fuses...#22 will fuse at 10 amps...

Long before the 100 amp battery capability will be exceeded....

I will do that when the design is final. Right now I am still in the schematic stage and the actual components to be used are not yet determined. Its basically a capicitor storage shifting design that checks and redeposits a small amount of charge 2,000 times every second so that the battery always stays in balance.

I can understand that. Modifying the battery is not a lot of work but it is extra if the person receiving it isn't going to use it and doesn't want to pay for it. It took about 3 hours total time to do the mod including the "through chassis" connector...if you don't count the taking out and putting back of the battery which you would be doing anyway if you were refurbing a battery. The total parts cost was $5 for the barrier strip, $1 for the printer cable at the thrift store, about $3 for some wire and the solder on connectors and $6 for the "through chassis" connector. It would take less time and less money if the cable was just directly connected to the subpacks, but I wanted heavier wire to the subpacks from the barrier strip so that I could run heavier currents on them for the initial balancing where I run a discharge of 2 to 4 amps. The printer cable is designed only for data transmission and for the dynamic balancer which will not be high current.
My main reason for doing this is that I am heading toward a 3 or four battery car and the data cables will be run to a 4 port data switch, available at the thrift store for $3, so that I can check the health of all the batteries without removing them and so that I can ballance them without removing them.
