i have a 3000 watt inverter running off a 660 amphour 12 volt battery bank. i occasionally will pull close to 300 amps for several minutes from the battery bank. this seam like it would exceed the amp rating on the 220a smart battery protect unit. could i run 2 of these units in parallel to provide the amperage capacity? or is there another similar product. my primary desire is adjustable/programmable low voltage cut off protection.
