2x 7S28P = 7S56P without series cell connection

Hey Guys,

I've got 2 pack of 7S28P of LG MG1 and I need to make 7S56P, but...due to the fact they are in own casing I do not want open them up and Connect 28p with each other. (two 7Sseparate balancers)

So they will only by connected by plus and minus terminals creating 7S56P with separate 28cell.
I hope it's clear enough :angel:

How bad idea is it?

Its fine as long as you have 1 bms per pack. Controlling each pack that is and taking care of it.

Nothing wrong with connecting them at the absolute ends. Just make sure to have a fuse between each bank to the busbar, so you'd have 2 fuses in this current setup. If you add anymore, you'd have another fuse for each one.
Ideally, just a suggestion, if you could put a shunt on each bank/string so that you can tell if 1 string is pulling/draining faster than the other. If each one has it's own bms, you might be able to use it for this information instead.
