"[they] hold five times as much power, at the cost of taking five times longer to be fully charged." Phrasing is poor here, taking 5 times longer to charge is not a "cost", as you could just as easily take them off after waiting the normal charge time and still have just as much power as if you were charging a normal power cell. It's definitely worth mentioning, I just wouldn't phrase it as though this is some sort of trade-off.
