Review: Great Battery Post Connectors!! - Have an auto battery powered race bike starter that has the space in the device for the heavy battery to set in. Of course, that situation makes it very heavy and hard to move around even with the inadequate wheels on the unit. For ease of transport and use, I worked up a remote battery connection with heavy duty fittings using these beauties on the starter side that connected the remote battery from outside the framework. Now both items could be handled separately and connected at the track in lieu of looking for a hernia lugging or dragging a heavy one-piece unit from place to place. The added benefit is that the heavy battery should be removed from the starter for recharging to ensure no damage to the unit when getting ready for the next race location. Now I can set up the starter, connect the battery remotely and let the starting and racing begin!! These battery posts were easily mounted with the included screws, of durable and electrically safe material and of great value for the money!! ## Features - Product: A pair of single stud terminal 12V junction block, includes a positive power distribution block red and a negative power distribution block black - Heavy Duty: The 12v battery junction block rated 250A when work in 12v circuit, and the battery junction block can work with MAX 48v power - 3/8" Stud Terminal: The battery post is single 3/8" M10 stud terminal design, which makes the 12v bus bar terminal block be able to accept large size terminal connectors and wires - 316 Stainless Steel Material: The Stud of the terminal post is made of 316 stainless steel, which makes this 12v junction post have better corrosion resistance performance compared with 304 stainless steel made battery bus bar - Wide Application: The Heavy Duty Insulated Junction Post Block aims to make the wiring of circuit become neat and tidy, prevent electric short circuit, suitable for automotive, car, truck, marine, boat, solar wiring, etc ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B2LK7KDR | | Best Sellers Rank | #18 in Distribution Connecting Blocks #52 in Audio & Video Distribution Products | | Brand Name | Joinfworld | | Color | Single M10 | | Connector Type | Screw | | Current Rating | 250 A | | Customer Reviews | 4.6 out of 5 stars 402 Reviews | | Included Components | 1 x Positive&Ground Power Distribution Block | | Item Dimensions W x H | 2"W x 1.5"H | | Item Pitch | 0.38 inches | | Manufacturer | Joinfworld | | Material | Nylon, Stainless Steel | | Material Type | Nylon, Stainless Steel | | Model | BB1-1A-RB | | Mounting Type | Surface Mount | | Number Of Contacts | 1 | | Number Of Poles | 1 | | Number of Items | 2 | | Number of Positions | 2 | | Part Number | BB1-1A-RB | | Pitch | 0.38 inches | | Specification Met | CE | | UPC | 751717591588 | | Upper Temperature Rating | 90 °C | | Voltage | 12 volts_of_direct_current | ## Product Details - **Brand:** Joinfworld - **Color:** Single M10 - **Connector Type:** Screw - **Current Rating:** 250 A - **Item Pitch:** 0.38 inches - **Material:** Nylon, Stainless Steel - **Mounting Type:** Surface Mount - **Number Of Contacts:** 1 - **Number Of Poles:** 1 - **Voltage:** 12 volts_of_direct_current ## Images ![Power Distribution Block 12V 3/8" Single Stud Bus Bar M10 Insulated Battery Post Junction Block for Marine Boat Automotive - Positive&Negative - Image 1](https://m.media-amazon.com/images/I/71paLaIn+8L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for the job *by D***S on September 1, 2026* Good solid compact units for bridging several battery cables in a convenient location on vehicles or home generators. ### ⭐⭐⭐⭐⭐ Great Battery Post Connectors!! *by M***7 on September 12, 2026* Have an auto battery powered race bike starter that has the space in the device for the heavy battery to set in.
