i got the guest 2611a which i bought for 2 batteries, but you can save some money and get the 2608a and save $40, it will just charge 1 battery.
Product Features
- Dual marine battery charger for 12- and 24-volt batteries
- 3-stage electronic switching circuit; 5 amps per output
- Includes two 4-foot DC cables with ring terminals
- 6-foot AC cable offers ConnectCharge plug
- Measures 7.75 x 5.5 x 2.42 inches (W x H x D) The alumanum 1/4 plate i mounted under it was cause i wasn't sure how hot it would get. it's about an inch or so wider than the charger on all edges. these chargers have the best reviews i have found. dont buy the basspro chargers.
