Ideal for experimental aircraft, race cars, and touring motorcycles, this battery combines lightweight design with smart technology to keep you flying or riding confidently. ## Description The ETX680 lithium battery has a lot of punch for such a light battery! This battery is intended for an aircraft engine of 400ci or less; 60 amp alternator/generator or less. Can be used in experiemental aircrafts or race cars, just match up the alternator output with the correct battery. This is also an excellent battery choice if you have a touring motorcycle. If your motorcycle has a V-twin engine larger than 110 ci, then you should upgrade to the ETX900 as it delivers the additional cranking amps needed for a V-twin engine start. Our ETX battery series is fully protected by an integrated battery management system (BMS) that protects the cell’s from over discharge, over charge, short circuit, temperature, plus cell balancing to ensure charge levels are equal. Additionally, our ETX Hundred series batteries have redundant electronic circuits and battery fault indication. The fault indicator can be connected into your EFIS or wired to a 12volt LED light on your control panel (SOLD SEPARATELY) to alert you to the state of charge and state of health of the battery. (Please see manual for details) EarthX is proud to be the most trusted brands in the experimental aircraft market. ## Features - Only 4.1 lbs and has 320 CCA / 680 PCA , 12.4Ah. - 60 amp charging system or less! - Last 2-3X longer than lead acid! - Will not freeze, boil or corrode! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WC4H124 | | Battery Type | Lithium | | Best Sellers Rank | #911,230 in Automotive ( See Top 100 in Automotive ) #2,334 in Powersports Batteries | | Brand Name | EarthX | | Compatible with Vehicle Type | Motorcycle, Passenger Car | | Customer Reviews | 5.0 5.0 out of 5 stars (5) | | Item Dimensions D x W x H | 3.1"D x 6.5"W x 6.6"H | | Manufacturer | EarthX | | Manufacturer Part Number | ETX680 | | Size | 6.5" L x 3.1" W x 6.6" H | | UPC | 711347112300 | | Voltage | 13.2 Volts | ## Product Details - **Battery Cell Composition:** Lithium - **Brand:** EarthX - **Manufacturer:** EarthX - **Product Dimensions:** 3.1"D x 6.5"W x 6.6"H - **Size:** 6.5" L x 3.1" W x 6.6" H - **UPC:** 711347112300 - **Vehicle Service Type:** Motorcycle, Passenger Car - **Voltage:** 13.2 Volts ## Images ![ETX680 Lithium Iron Phosphate Battery (LiFePo4) for Aircraft with BMS (60 amp alternator or less) - Image 1](https://m.media-amazon.com/images/I/71DE8i7akhL.jpg) ## Questions & Answers **Q: Which side has the positive terminal? a picture would help** A: The battery is symmetric so the terminals are placed in the center of the battery.
