The maximum charge current is 15 amps when the starting battery is 1/2 volt to 1 volt DC less than the house battery. The Digital echo-charge is designed to work on 12 VDC or 24 VDC systems. The Digital echo-charge is a voltage-follower, following the three-stage charge modes of the Freedom Charger.
THINGS YOU SHOULD KNOW Use only deep-cycle batteries in your house battery bank. Only similar batteries should be connected together in one bank. Do not connect old and new batteries together or wet and gel cell batteries together. Always use properly sized terminals and cables for your interconnecting battery cables.
BEFORE YOU BEGIN The Digital echo-charge should be unpacked immediately upon receipt, and inspected to determine if any shipping damage has occurred. No special handling is necessary; however, care should be used to avoid dropping the unit or exposing it to dust and moisture.
Protect your skin from harm by wearing clothing that will cover your arms and legs when working with batteries. The Digital echo-charge is intended for vertical mounting. Mount in a location that provides the greatest convenience when making the wire connections to the batteries.
Prevent unnecessary damage by carefully following the installation instructions. Battery Connections Two feet of 16 gauge wire with a ring terminal on the end is connected to the Digital echo-charge unit. Connect the ring terminals to the batteries as indicated. Connect from the echo-charge: •...

OPERATION When the input voltage is 13.0/25.5 volts DC or higher, echo-charge automatically switches ON. The LED glows a steady green. When the input voltage is lower than 13.0/25.5 volts, the echo-charge automatically switches OFF, and the LED blinks green. The output voltage of echo- charge is limited to 14.4/28.8 volts.

It is important to install the Digital echo-charge in a well-ventilated location. An elevated temperature may cause the Operation LED to glow red and turn the echo-charge OFF. When the temperature cools down, the LED will return to green and the Digital echo-charge will resume normal operation. Operation...
TROUBLESHOOTING PROBLEM THINGS TO CHECK LED is red. 1. Check to see that the Digital echo-charge Thermal has sufficient air flow and ventilation around it. shutdown 2. Check the battery connections. 1. Check the difference in voltage between the house battery and the starter battery. If the difference is greater than 2 volts, the Digital echo-charge will reduce the charge current.
