Hey all,
I want to add 4S or 6S to my existing premade BMS 12S 13ah pack. Since HK doesn't sell 13ah packs, I will have to parallel 2 packs to get to 13ah, and then series that with my exiting 12S pack. My existing 12S pack is a Li-NMC, a form of Lipo, I believe it can do 60amp continuous draw. I assume any of the Lipo HK sells will be ok? What C rating should I stick with? Will there be an issue with mixing my 2.5 year old (only <2K miles) battery with the new cells? I will be using this on my 40amp Grinfinion controller.
There are two methods (or more) to charge. I can get dumb battery supplies and use a balance charger like these two setup:

Or maybe this power supply from Icecube:

Or I can get a smarter power supply, like a meanwell that has adjustable voltage and current (any recommendation and is Ebay safe to buy a genuine one from?) , and use a Battery Medic type device like so:

Once my main 12S pack dies, I plan to either replace them with more HK Lipo cells, or switch over to Adappto, so I hope whatever I buy I can also use later on. Could you all check my rough idea, thanks.
