You are very correct, a 24v on a 12v system using a pwm controller is a waste

it can still go 2kw or more when you still drain the battery to 9v, that's 3v per cell

I'm sorry I can't say how much it cost me to build since it's a DIY thread.

Really?? I thought DIY is meant for people to build their packs through information from like-minds?

Ok. On a closer look, I guess you market your packs here for sale, and this is the reason why you can’t answer the question.
