Satisfied

Have not installed yet, but I am sure it will do the job for me. Will write review after install.

J
Joe Laratro (Fort Lauderdale, US)
Very excited to charge my AGMs and Lithium batteries

This charger was a larger profile than the 4 bank Minn Kota that I was replacing. I had to relocate it, but that worked to my advantage. It is now easier to see the charge status. I connected to the batteries before changing the profiles. it defaults to lithium. I pulled the fuses from the AGM connections, changed the charging profiles, reconnected the fuses and -- ALL GOOD.
