Hello everyone, I'm trying to assemble my first battery pack but I am afraid I did some mistakes during the assembly:
My main concern are the vibrations. I have assembled the pack without using hot glue between the cells (I just tried lately to pour some between the series but it's quite weak), I have just spot welded the nickel strips and I would shrink wrap the pack with 2 layers afterwards... I'm though concerned that this won't be secure and safe enough for the cells facing constant vibrations which could lead to failure of welds.
I am also going to use the battery pack into a soft pouch as container, therefore it will be more subject to movement.
What do you suggest me to do in order to make this pack safe and durable?
I've thought to apply some 9mmx900mm nylon zip ties tightly on the battery perimeter, add 2 layers of thin plexiglass on the poles (and secure with zip ties as well), a thin layer of closed cell foam and shrink wrap. Can it be enough ? Or is it too much?
Another little concern is about 2/3 cells which I accidentally shorted for less than 1 second during the assembly. As you can see at least one in the image above, the plastic wrap is wore a little. I tried to measure the voltage of the external shorted cell and the voltage is 3.7v, while the rest of the cells are 3.6v...
Should I worry about these shorted cells?
Thank you very much for reading.
Ps: pardon me for my English.
