Batteries
I have added another battery to my E25, but if I were to choose what I would really want, it is AGM's. They have a better track record for not discharging nearly as much as flooded batteries. Also, they seem to hold up better to slight overcharging (gel's can be fried by this) and they don't leak shen they are not flat. Of course, at twice the price of flooded, they can dent the wallet pretty badly.
