Well, I am taking my time, got kapton tape, as the hot glue is wimpy, so I will wrap around the packs. IF it is stiCKYYYYYY tape, I will wrap with paper or such first. I will wrap the wires and nickel strip under it as well. So, only the ends are exposed, for checking PER CELL voltages. The tape will help with the HDDDDDDDDDD Velcro mountings. On the sides, I monkey snotted YOGA MAT, they float nicely. BUT velcro rips the hot glue.
Got a switch, and a green panel mount led. I had to REMAKE the pipe. I used a 3 inch ABS this time, as heating a PVC pipe makes CYANIDE. So, I heated it, inside and out, and used wedges to do it a little at a time. So, it is wavy and such, BUT it is thick, SO, I keep bending it till it is PERFECTIsh. So, I sand it till it is.
I used the junk first try, to band saw some seperators. I supeglued them down. Just enough to insert Mmeter probes.
I got originally made an XT60 one to four way converter, but it is bulky, so, I got a 30amp terminal strip, eight places. SO, I use a common wire tie for two separate areas. I then have the capability to detach the parallels. I can take out the units of nine cells for repair. They float and so will use wires to series across units. They will be soldered at middles, so they can quickly be detached for removals. I will make a plastic top, velcroed as well. To insulate the cells against any possible shorts.
So, I can remove the parallels, and per cell charge. This is done at the terminal strip. This is FAR better than a BMS. I use a 30 amp manual reset circuit breaker to guard against overamp.
SOOOOOOOO, I am waiting for my kapton tape, and then finally will finish.
Oh, I got some cool purple sparkly pain, and primer,
FIRST. Then I will use my auto paint later.
It is another say inch deeper, ovalized. But doesn't look much bigger. I tapped the cable guides on the bike, and used a bolt counterbore, with buttonhead SHCS s to make it look SLICK. SO, I wont make it quick change. I will live with 21 ah sssssss with aux attached. I must assure the two packs are full, before paralleling them for long rides.
IT looks pro, I will have almost no wires/cables showing. It took mega hours to heatform that ABS reliably and correctly. BUT, it HAD to be done. This prototyping takes a while.
SO, I have a switch, green led, 48 to 12 converter, all waiting for kapton tape.
Then one days work, and ride.
Oh, the aux pack will hang from the seatpost, using a seatpost clamp, with neoprene insert to neck down. Then, a simple piece that has a capability of snapping around the seatpost. Wont take much to stabilize. All forces will be on the clamp on top. I think I will do wood, and then I got some exotic veneer. This will NOT interfere with my TOPEAK rear rack and MTX bag. So, I can go to stores and wheel it thru, filling the bag, without putting bike down. They scream at that, liability you know.
I have a small hydration pack. It is pretty comprehensive kit I have assembled.
