I have "trays" of HR1221W SLA batteries from a defunct UPS that I just couldn't leave alone, and needed an inexpensive way to turn 8 12v batteries wired in series (for 96v total) into 8 12v batteries wired in parallel (for 12v total) so I could power some more common DC loads. This bus bar does the job, leaving me two pair of terminals to hook up a pair of loads. It's not what I was envisioning, but works perfectly. Construction of the part is solid (as are most things from Blue Sea) and while the price seems high for such a simple product it's inline with other similar options... maybe even cheap. Each of the 20 terminals is a #8 screw, so #8 spade or ring terminals work perfectly. Review: Perfect fit - Good snug fit but no backing ## Features - Number of Screw Terminals: 10 per bus - Closed back design completely insulates power from the mounting surface - Product type :SPORTING GOODS - 100 amp 300VAC/48VDC capacity ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000277JB4 | | Brand Name | Blue Sea Systems | | Color | Beige | | Colour | Beige | | Connector Type | Screw | | Connector type | Screw | | Current Rating | 100 Amps | | Current rating | 100 Amps | | Customer Reviews | 4.7 out of 5 stars 209 Reviews | | Global Trade Identification Number | 00632085027025 | | Included Components | Item | | Item Weight | 0.3 Pounds | | Manufacturer | Acr Electronics | | Material | Stainless Steel Aluminum | | Material Type | Stainless Steel Aluminum | | Model | 2702 | | Mounting Type | Surface Mount | | Mounting type | Surface Mount | | Number Of Contacts | 10 | | Number Of Poles | 10 | | Number of Items | 1 | | Number of Positions | 20 | | Number of contacts | 10 | | Part Number | 2702 | | Specification Met | UL | | UPC | 632085027025 | | Unit Count | 1 Count | | Voltage | 48 Volts | ## Product Details - **Current rating:** 100 Amps - **Connector type:** Screw - **Number of contacts:** 10 - **Mounting type:** Surface Mount - **Material:** Stainless Steel Aluminum ## Images ![Blue Sea Systems DualBus 100A Common BusBars - Image 1](https://m.media-amazon.com/images/I/61s33wFJoAL.jpg) ![Blue Sea Systems DualBus 100A Common BusBars - Image 2](https://m.media-amazon.com/images/I/71vZoScNBwL.jpg) ![Blue Sea Systems DualBus 100A Common BusBars - Image 3](https://m.media-amazon.com/images/I/611V0n4ZqRL.jpg) ![Blue Sea Systems DualBus 100A Common BusBars - Image 4](https://m.media-amazon.com/images/I/51x+DKjD8nL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Each of the 20 terminals is a #8 screw *by T***G on 21 August 2018* This is not what I was looking for when I found it, but it does the job perfectly.
