Product Description
Manufacturer Part Number: GEN5X3
Multiple-banks- A three-bank on-board battery charger rated at 15-amps (5-amps per bank) for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries. Independently charge and control each battery bank with selectable charging modes - including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode - for all types of lead-acid and lithium-ion batteries. An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates. Charge dead batteries - Charges batteries as low as 1-volt. Or use the all-new force mode that allows you to take control and manually begin charging dead batteries down to zero volts. Restore your battery - Automatically detects battery sulfation and acid stratification to restore lost battery performance for stronger engine starts and extended battery life. Designed for water - A fully-sealed and waterproof onboard battery charger with an ingress protection rating of IP68, but has survived brutal life cycle testing, including thousands of hours underwater.

Overall Great product. A couple small issues that might be user error. One being that I get a better charge on the standard 12V setting than I do on the lithium setting, even though I have lithium batteries. Also, I'm only getting about 190 watts max when I have the generator running. However, that may be the limit for a deep cycle charging system. Plenty of cord, everything is plug n play so very easy to use.
