I'm in the process of switching over to a 6s setup from 4s. I recently purchased three 4s 30c 8000mah packs that have not been used and are still sitting in the box. I'd like to hack them up into two 6s 30c 8000mah packs. Any pointers tips or advice? The tricky bit will be wiring up the balance connection. Can someone point me to any helpful tutorials?
