you can get a 2 bank minn kota fully automatic charger at wal mart for around $115. get one and youll wonder how you ever did without it. permanently mount it, fish, get home, plug it in,and leave it plugged in until you go fishing again. i have my outside outlet on a timer, and it kicks on 15 minutes every 3 days to top the batteries off. since ive gone to an onboard charger, ive yet to have a set of batteries last less than 5 years. the main advantage besides adding battery life, is they are buillt to be waterproof and shock resistant. if you have your battery charging and a pop up thunderstorm dumps rain unexpectedly, its not an issue.
