Just bought a 3 bank on sale at BPS for $139. It is 5 amp per bank. Like it so far. The biggest selling point for me VS. The minn kota was bps warranties their charger for 2 full years. Anything goes wrong. Take it back to them and they replace it. Minn kota warranty was after 30 days. I would have to send it back to minn kota. At least that is what the salesman said. Box says it is waterproof and shock proof. Just my 2 cents.
