LiFeMnPO Van Auxiliary Power Project

(Small Screen Version)

Block diagram of components with voltages & specifications Engine: 150 A ANL fuse; solenoid; solenoid activation wire; 2 AWG to LiFeMnPO in back of van
Curve for discharge and charge Voltages for a LiFeMnPO cell Meter power & signal; 100mv/100A shunt; 2 AWG chassis ground cable; 150A ANL fuse
Discharge curve for lead-acid chemistry batteries (FLA, AGM Gel Cel) LiFeMnPO installed in the back as the house battery
Power & energy density of various capacitors, fuel cells & various battery chemistries LiFeMnPO meters' hook-up diagram
Big Picture
Red-hot wire carrying 15 Amps with a test LiFeMnPO battery Ignition off: separates LiFeMnPO from the van's electrical system. Current is actually zero, not .4 A
Fuse block; solenoid; 2 AWG cable; fuse block; LiFeMnPO; 10 AWG hook-up wire; Anderson contact; LVD; load sockets; refrigerator socket; 110 V AC inverter; refrigerator cord Key turned, engine off: -11.1 Amps LiFeMnPO current charging van battery and powering accessories
Soldered small wires to a few strands of the large cable before crimping with conductive paste; Anderson connecter @ top Engine running: 31.4 Amp current shows LiFeMnPO being charged by the van alternator
Low-Voltage Disconnect is a must for saving any deep cycle battery from under-voltage severe damage (we use 11.5 V) Overhead LED floodlights shine light on the meters for night driving
