HXR Backup Battery "Dropping resistor" ?
Posted: Thu Jul 09, 2020 1:40 pm
I bought a Velocity with a single HXR installed, and I've been going through all of the configuration and understanding it's connections.
There is a backup battery installed.It is connected like this:
From the Positive terminal of the main battery, a thin wire (18?) runs to a big dropping resistor (25w1d2, apparently a 1.2 OHM 25 WATT) then to the positive terminal of the backup battery.
Why would this arrangement have been made? It would not prevent back current to the main battery and seems to ensure that the backup battery charges to a lower level than the main battery. Perhaps as the backup slowly charges it draws less and less current and the resistor becomes no factor? Does anyone else connect their backup battery like this? Issues?
