#Cole hersee smart battery isolator upgrade#
This easy battery upgrade sets Project Bedrock up to handle any electrical need we might encounter in the field. One minute later it automatically disconnects the battery it’s connected to (we will use it with the auxiliary) from whatever accessories are attached to it.Īutomatically isolating the auxiliary battery in this way keeps it protected from total discharge, which could be the case when running lights or other accessories when one is away from the truck for a period of time.
This unit sounds an alarm when battery voltage drops below 12.1 volts. We also installed a Cole Hersee SureStart Compact Low Voltage Disconnect Switch (#48513-01) on the firewall to use as our “hot point” between the auxiliary battery and future strobe lights and accessories. Should need a “boost” at start, an optional “momentary switch” can be easily wired in to the Smart Isolator that connects both batteries for one minute once it’s activated
Wiring in the second battery is as simple as following the C/H wiring diagram. When you start the truck, the charging system brings the cranking battery back to 13.2 volts (full charge), then the isolator closes, the red status light turns on, and the alternator now recharges the auxiliary battery. This separation protects the starting battery while allowing the auxiliary battery to continue to power the auxiliary loads. When the isolator senses the batteries reach 12.7V it opens the solenoid relay to separate the two batteries and turns off the status light. SMART IOSOLATORįor example, you pull the truck in to a jobsite, turn the engine off and leave all the warning lights on. This 200-amp isolator senses the voltage of both main and auxiliary batteries and connects/separates them according to their charge, always protecting the main “cranking” battery. To connect the two batteries properly, we selected a Cole Hersee Smart Battery Isolator (#48530) designed to work with today’s electronic charging systems. The Odyssey is far more receptive to deep discharging and resistant to the hard pounding from off-pavement use than the OEM battery. So we chose an Odyssey 78-PC1500-A AGM battery as the auxiliary, which delivers 880 CCA and 135 minutes RC. It’s almost identical to a Group 34/78 or Group 78 battery. The factory AC-Delco Group 48 battery is unique to GM trucks, and it’s rated at 615 CCA (Cold Cranking Amps) with 110 RC (Reserve Capacity). Odyssey 78-PC1500 AGM battery, Cole Hersee Smart Isolator and SmartStart low-voltage disconnect are the heart of GM 1500 dual-battery upgrade.Īll you need is a GM Battery Retainer (#14005061) that costs less than $5 a second battery and a battery isolator designed to work with the new electronics. Whatever the reason, it does make it easy to double-up the batteries. There’s also an unused battery tray on the driver’s front corner there’s no TP2 (dual-battery option) for the 1500s, so it’s bit of a mystery why it’s there. Stock Chevy/GMC 1500s come with a single Group 48 battery located in the passenger’s-side rear corner of the engine bay. In preparation for adding an inverter, warning lights, and a few other work truck “necessaries” on Project Bedrock - our 2011 GMC Sierra 1500 Crew Cab 4×4-we decided it was a good idea to double-up the batteries. Sometimes hard enough to leave you stranded. Inverters, coolers, radios, warning strobes, laptops, battery chargers, printers and other necessary accessories put a big drain on any pickup’s stock electrical system when the truck is on a jobsite with the engine off.Įven with the engine running the amp load needed to power such an array of accessories can put a strain on the stock electrical system of today’s half-ton pickups.Īdd a plow, connect to a weak trailer battery, or flip on auxiliary driving, fog, or work lights and the battery is going to take a hard hit. Turning the key to discover nothing but a dead battery isn’t fun. Project Bedrock DUAL BATTERIES Upgrading to dual batteries gives working Chevy/GMC 1500s a big electrical buffer Odyssey and Cole Hersee make it easy
