lots of variables to consider... but generally I think you have the right idea. Any chance the pack is a LiHV pack? Only reason I ask is because you might be shorting yourself some capacity if the pack was designed to be charged to 4.35V/cell instead. I've got a 6Ah shorty pack that is LiHV but I only charge to 4.2V/Cell... so I never get close to the rated capacity, but I'm okay with that, idea being that the pack should have a longer lifespan if not maxing out the cells to their rated capacity
