Its the same factory install kit that every espar dealer sells. About to order mine here in a minute. $865 shipped to OH (batteries plus)

Kenworth dealer has a good price here but it looks like you need a special card.

$865 is Espar only...Isolator , battery and other wiring extra....IE: fusable link.

the beauty of the TK house brand battery is its 3 year FULL warranty....none of that prorated crap...

Do you see a battery or isolator here w/ extra wiring? Just trying to make sure its the same kit every other espar dealer sells.(see photo in link) Espar Airtronic D2 Truck Kit w/Digi-Max controller

KW wants tax on their espar pushing it over $900 shipped.

Battery, isolator, large cables and lugs, make sure you fuse the cable from the isolator to the battery.

Battery Depot says he has everything else needed outside the kit. He wires the espar to the vehicle battery. He said when I put a power inverter in he would rewire it no charge.

thats what i meant about the fusable link....:)
I kinda figured, but I didn't want someone to think that meant the link between the Espar and the battery.

The Espar wiring is already fused, of course. But any connection to the battery needs to be fused, whether it's an appliance of some kind (including an inverter) or an isolator.

Don't let them wire the Espar to the vehicle's starting battery. It needs to be wired to a separate battery. A 1 amp draw can kill a starting battery overnight, especially if the battery is a year or more old, and especially especially if it's cold outside, because the colder it is the fewer amps you have available in the first place. A 1 amp draw from a 0 degree F battery is Peukert Corrected to 1.71 amps because of the temperature. And because it's cold, the Espar may spend considerably more time at Medium or High power, drawing 1.5 to 2.0 amps per hour. That translates to an effective Peukert Corrected draw of 2.1 to 2.8 amps per hour.

Let's call it 2 amps per hour. You've been sitting 12 hours, so that's 24 amps gone from the cranking battery. That translates to 40% of your Cold Cranking Amps, on a 1000 CCA battery. When it comes time to crank the engine, not only are there fewer amps to begin with because of the temperature, but you've removed more than 400 of the CCA to the Espar. So instead of 1000 CCA, you've got 600 or less. So the battery will have to work even that much harder to start the engine. Even if it starts the engine, it's classic textbook on how to dramatically shorten the lifespan of a cattery.

Cranking batteries are designed to start the engine, to give large amounts of amps in a short burst. They aren't designed for anything else, nor should they be used for anything else. Marine deep cycle (and truck batteries, they're the same) are designed specifically for long term, low amp draws, the exact kind the Espar draws. In the same way a cell phone battery is designed for a cell phone, an auxiliary deep cycle battery is designed specifically for what you need it for. You wouldn't connect your car battery up to your cell phone, so why connect a long term, low amp draw appliance to your cranking battery?

Where can I get a good auxiliary battery that will fit in sprinter under the seat or hood? Any links or type of battery to look for? Need something on the cheap, already forking 2 grand between the espar, installation, roof vents and insulation. :)

You're just looking for a marine deep cycle or a truck battery. Something in the $100 range, +/- $20. 100 amp hours.

Under the hood, probably not. Under the seat is better for AGM or at least maintenance free. Otherwise you can mount it behind the seat, near the Espar heater. You'll want it secure, and with some battery mat underneath to absorb any acid spills. It's like a felt material, acts like absorbant baking soda.
Walmart, Autozone, Freightliner, Cabela's, Batteries Plus, Interstate Battery, Sears, anywhere that sells batteries.
