Replaced rear axle with 01 Blazer disc brake unit with 2900lb axle rating, an upgrade from the factory 2300lb drum brake unit. This allowed me to up the battery count under the bed to 22.

7 batteries on either side of the drive shaft with two partially under the cab. Rear rack holds eight.

This gives me 132V under the bed plus the other two under the hood.
System Voltage144 Volts
ChargerZivan NG5
Charger operates at 208-240V single phase so I can charge at work and home.

Charging is via a 50Amp 250V "Recessed Inlet" behind the gas cap cover.
HeaterCeramic 1500W from EV-America. It puts out about 2100W on 144V. Also lined the floor and panel behind the seat with radiant barrier.

DC/DC ConverterIota DLS-55
55Amps @ 13.6V. This unit is configurable with a jumper to output a dual-voltage, 14.2V during vehicle use and 13.6V when the vehicle is off. At 13.6 the battery wasn't holding up well so it's fixed at 14.2 now.
InstrumentationFactory temp gauge on the motor. Uses a thermistor rated 2252 ohms @ 25C or 77F.

This is our company errand vehicle and my commuter. Doing our little part to reduce pollution around Spartanburg, SC and our dependence on foreign oil.

I hope to do a full size van when the battery technology becomes affordable with AC drive and no transmission!

Thanks for looking!
