Out-of-pack HV Module Chg/Discharge Questions

Look if you look at the plastic ends and the 12 mm bolts and the rods that hold everything clamped together I would think clamping between 2x4s or 2x6s and a regular carpenter clamp run up to touch and give an umph should get it You shouldn't have to squeeze it till it squishes You're just trying to hold it so it doesn't expand under charge and discharge cycles we're not trying to kill it it's only squeezed between plastic and other modules to begin with so I guess if you wanted to you could check with let's say a dollar bill and see if that will fit between the modules when they're clamped and then try feeler gauges they come way down to even thinner than a dollar bill see if anything will even get in there and then try to clamp to that use that feeler gauge to rack up four modules eight nine whatever and put that fueler gauge in until you have about the same force I mean it doesn't have to be any kind of exact torque or anything You're just trying to keep them from expanding from where you clamp them

 

You don't need pressure per say, you just need to prevent expansion. Some clamps and some plywood will be fine. Not that much force involved. You're just adding structural stability to the thin foil sides.

 

If you have test module(s) you can charge it 350 mA for a few hours and get voltage and temp readings when you notice the module(s) start to swell. As the module(s) cool the swelling goes down close to before the charge started, but some have reported trouble getting modules clamped back into the packs case.
Testing modules at 40° F ambient temps will have much different results than if tested at 80° F ambient temps.

Much like PriusCamper, TMR-JWAP has done a lot of module work, TMR-JWAP 's CQ3's are most likely a bit different than the skyrc's setups, making it harder to determine the best way to setup cycles for what you have in the way of modules to work with.
For module reconditioning the charge and discharge settings on the hobby chargers never made any sense to me just reading about them, and from my experience with pack reconditioning.

Maybe this post will make as much sense to you as it does to me when I read it.

There's people on here who have argued that you can charge modules briefly when they aren't clamped down with no issue... It all comes down to heat. The expansion is going to happen when it heats up.

 

I don't see what's so hard about racking them up either in the case or between two clamps I should be like easy peasy just take a second and you just want to clamp them up gently so they can expand You don't have to kill them

 

I have several of the white plastic end pieces from module packs. Combine that with 4 pieces of 5/16" all thread and nuts. You can clamp however many you want. A fully discharged or partially charged module can take a decent amount of charge without swelling as long as you keep the charge rate low and don't generate heat. A good module that is in a low energy state should be able to absorb 2-3000 mah with no clamping or cooling air.
