RV-8 battery cable size?
Trying to figure out the big cables. I have an RV-8 with a rear battery, master contactor on battery tray and starter relay on firewall. I am planning on using 2 awg from the master to starter contactor for voltage drop. Also planning 6 awg for alternator to starter contactor via 60 amp ANL and 6 awg from starter relay to VP-X.
What is the recommended size for:
1. Battery to airframe
2. Battery to master contactor
3. Starter contactor to starter
Could go 2 awg for max power or 6 awg because the runs are short and more flexable to keep pressure off of the battery terminals.
