I am sorry if this has been answered but I am on time constraints and cant do a search. I have an ego passthrough which I love but it is killing all my attys within a few days. This battery is longer than my regular ego. I guess it is more powerful too. Sorry but I dont really get the ohms thing :-(. My question is what atty should I be using? apparently I am doing something wwrong. I have used Bauway LR and Boge regular attys. Any ideas? I am down to one atty and need to order but dont want to keep killing attys. Thanks for any help! Lisa
