Where could I find the max amps I can use to charge them? Charger can do up to 5a. Packs are TURNIGY 5ah 6s1p 25c
Yeah jumper wires. Usually thereâs a rating on the sales site?
Local eBay sale. Iâll see if I can find anything online
Whatâs the C rating on yours?

25c. Same as that one
Probably safe to do 2c, just keep an eye on the temperature

those are pack voltages, check cells voltages in each pack too, might need to balance each pack first

Iâll be plugging them all in my balance charger beforehand. Should I do a 5 cycle run?
2 should be enough
I just like it cause it looks good and itâs flat⌠Lol
Those direct-heating tips are practically magical.

Thatâs not happening. The groups are glued together. Itâs one thing to have flexible P groups, but no ones trying to make every cell flexible.

That nickel âbendâ wonât help because itâs perpendicular to the flex between cells in the p group.
Better to glue cells together with good amount of silicone on both sides for a solid connection. Allow for flex between p groups.
Iâm not trying to make every group flexible, rather to accomodate what flex there will inevitably will be. Glue doesnât have an infinite youngâs modulus, and neither do battery cells themselves. Theyâre gonna flex, no two ways about it. Itâs just a matter of how much, and whether that amount will cause problems.
But looping the nickel between cells like you have shown is not going to change the flexibility of the nickel. (Itâs in the wrong direction)
Yes it will, because it breaks the âbeamâ conformation of a perfectly straight piece of nickel strip held vertical. It you âpre-buckleâ the nickel by introducing a hump, then it can twist at the hump because itâs no longer perfectly in line with the vector of the flexion.
Haha. How much flex are you expectingâŚ
Pre buckling nickel between each cell seems like overkill 
Not much. But maybe enough to pop some welds in a worst-case scenario.
