i just ordered a minn kota powerdrive 80# and two optima batteries. i need some advise on a good charger. it looks as though you can spend as much as you like on one if you care to. i am looking for the best bang for the buck on a 3 bank charger that will do the batteries some justice. i would like it to be water proof. it doesnt need to be super fast. as i always charge over night. the bass pro one looks nice so does the guest. i would love to know what you all use and what you like and dont like.
