If you run that new P-pack down too low you can damage it or cause a fire if you’ve bypassed the BMS, which is typically how an esk8 is wired.
Yes, Lii-PD4 will work great for fixing that. Use alligator clips and carefully connect just that P-pack.
carefully being the key word here

Thanks man !! I will be careful 
Just a little update on the process: I soldered the charger to the one pack … and it is now charging. So far so good 
it’s now up to 3.92V still counting
… 4.06V still counting
… 4.15V (88%) and still counting

Do you guys have any other suggestions of tests you want me to do? Going to bang the plank then bang the enclosure itself? As if I bottom out on the deck?
I’m looking for dummy weights rn then I will bang it in the next hour…
Put something heavy inside and vibrate the fuck out of it for 4 hours, see if the bolt holes crack.

I’ll need some kind of machine 
any suggestions?
For dummy weight can I use sand?
Do abec screw on pulleys work on cloud wheels? Ik their core is different.
u probably want something hard and has a fixed shape, and can rattle inside the enclosure to test it’s durability

I was thinking that too. What if I tape the sand into small packets? I was initially going to use sets of screws and Allen keys etc but it’s going to be painful to arrange it all again
Get some beefy bolts. A 21700 cell is generally 70g, think how many you’ll have in there, then put 20% more weight in bolts, nuts, washers and test

Yes. I have weighed my batteries. I’d get some big bolts if stores were open… and if I had money. I’ll go to the park by my house and see how much sand will fit I will wrap it in tape into segments so they can shake around. I’ll mix in some bolts too. *Actually I have some big rocks around my house so they can shake around and I won’t have to tape sand together
This is okay? Keep in mind that the batteries won’t actually move - snug fit, while this stuff is very loose. This test is more extreme than the forces the enclosure will face.

it’s not even a challenge. I made this enclosure way too thick to be weak. It’s also completely solid which most people underestimate since consumer plastic products are usually hollow.

Take one bearing apart and remove all the stuffs except the outer race. (Look up how to take apart skate bearings) Put a dowel in there and beat the other bearing out. Put the first bearing back together. Turn it upside down, put a dowel in there, and beat the other bearing out.
