Looks like you've found your max charging current then, just over 2C (twice the 'C'apacity)
Bare in the mind the quicker you charge them the more you'll reduce their lifespan.

He's right, it says in the manual the recommended charge current is 12A, the max charging current is 3C. But I stick to 5.8A unless I need to charge the battery quickly, and even then I never go above 10A. My batteries are still competitive after a year of heavy use.

Cheers

so really its more about how fast you want to charge and how long you want them to last.

so by making sure they are balanced and and charged at 5.8 you will still get the same performance as if charging at 12a

All of the above is true. Just make sure you balance charge them on a balancing charger, not an add on card.

I tried test charging these batteries at 20 A, but could not see any performance difference, either on track or when comparing the discharge curves using 10A discharge current.
