Ran my shorty pack 70c 4600 today and I was super impressed with runtime but it had alot of punch!
I was barely making 5 min qualifiyer in my rb6 with a 7.5 turned down to 70%.

Im gonna go run laps tomamrow and hopefully the battery will get better but it seems like it is way low on runtime cause my 3800 gave me alot more time than the smc
