No, you would need 2 (1 per lead going into the ESC). The leads pulg into the Dean's going to the Speed Control. It would be much safer to wire the packs in series and then attached the LVD on the bridges to the ESC(if you know what I mean lol). Basically, its a set of leads that senses voltage which you put on the Male Dean's plug coming from the ESC and is wired into the reciever. Simple to do, very hard to explain!
