Hardline Products Terminal Tender Battery Post Expanders for Flat Square Post Batteries

Hardline Products offers Terminal Tender Battery Post Expanders for Flat Square Post Batteries that are designed to safely power different accessories for a 12 V battery on any powersports vehicle. These days, we have more electronic devices than outlets, so power strips are a real lifesaver. The Terminal Tenders serve the same function for powersports vehicles. The two little attachments—one each for the positive and negative terminals—mount to any powersports battery with square bolt-in posts, providing space for up to six different accessory wires. The Terminal Tenders work with any accessories that require 12-volt power, and they can be used with dry or wet cell batteries. The Terminal Tenders enable each accessory wire to have a dedicated mounting point, so there's no need for stacking ring terminals and no loose wire ends that could potentially cause harm to the system. Instead, these Terminal Tenders provide a safe, and organized way to power extra accessories, which is good news for those who tend to have plenty of aftermarket parts that need power, like stereos, GPS systems, winches and heaters. Product Overview: * Designed for use on UTV's, ATV's, Side-by-Side's, and motorcycles with flat post batteries (L-terminals) * CNC-machined aluminum for precise fitment and contact to post * Includes (2) Tender blocks, (2) post 4mm hex screws and (6) accessory 4mm hex screws * Three different mounting options, side, front and top * Machined to fit on top of 12-volt battery terminals used in powersport vehicles * Includes both (+) and (-) terminal tenders * Can be used to connect up to (6) different types of accessories to your powersports battery * Use for chargers, GPS, winch and light-bars (charger, GPS, and light bars sold separately) * Terminal Tender assures your accessories are getting the full voltage they require and it's installation complies with proper wiring standards * The Terminal Tender will fit under seats on most Harley Davidson® models, where the battery is mounted with little clearance (if using for other motorcycle models, check "measurements" to confirm fitment before ordering)
