Plug & Play
The operation is simple and charging will commence upon connection. With no need to disconnect the battery from the vehicle, at charge start the LITHIUM US will automatically reset any low voltage protection electronics (Battery Management System) fitted. Charging can be restarted manually at any time using the ‘Reset’ button.
Fully Automatic
The CTEK LITHIUM US is a fully automatic ‘connect and forget’ charger with 8 charging steps including a testing sequence to show if the LiFePO4 battery can take and retain the charge, a unique maximization step to restore full capacity, and patented maintenance charging to ensure maximum performance even after months of inactivity. Splash-proof and dust-proof (IP65) the LITHIUM US is easy and safe to use, protects vehicle electronics, is spark-free, is reverse polarity protected and short circuit proof. The LITHIUM US features a 5-year warranty.
8-Step Program
- Accept: Tests if the battery can accept charge. This step prevents that charging proceeds with a defect battery.
- Bulk: Charging with maximum current until approximately 90% battery capacity.
- Absorption: Charging with declining current to maximize up to 95% battery capacity.
- Analyze: Tests if the battery can hold charge. Batteries that can not hold charge may need to be replaced.
- Completion: Final charge with reduced current.
- Maximization: Final charge with maximum voltage up to 100% battery capacity.
- Float: Maintaining the battery voltage at maximum level by providing a constant voltage charge.
- Pulse: Maintaining the battery at 95-100% capacity. The charger monitors the battery voltage and gives a pulse when necessary to keep the battery fully charged.

While traveling in Ethiopia as a tourist.
Format: Kindle
It is a very concrete and well written history of Ethiopia. While traveling in a photo tour I decided I wanted to know more of the contrasting country my shoes were on. I think this short book completes my need to my entire satisfaction

Informative, compact history of rulers, religion and struggles.
Format: Kindle
This book is well written. It filled out my knowledge of Ethiopia, which was mostly that it was isolated from neighbors and most empires. I had heard of biblical contacts, two Italian invasions, civil wars and famines.
In this book I learned of contacts with ancient Rome, Byzantium, the Ottomans, and Arabs. Trade carried on the silk road, and by sea. There was influence of Judaism, Islam and competing Christian sects. The sequence of leaders were covered as well as how they came to power. Many conflicts are covered, insurrections and invasions. The Haile Selassie period is covered, as well as his downfall. Then the military period is covered, with communism and factionalism. Finally the recent period is covered,up to the present civil wars of 2022.
I would recommend this compact book, for anyone planning a visit, or wanting background knowledge.

Don't get tricked into buying this book like I did.
Format: Paperback
This is a fake book written by AI. It reads worse than a Wikipedia article and is a complete scam.

A Rough, Rocky Start
Format: Kindle
Modern Africa started after a long rough and rocky start. This book describes the trials each district has had to face to gain their freedom from Europe and what life was like in each district under the control of foreigners. As WWI began, many of Africa's districts were effected, some were forced to supply fighting men, some had their resources used to support the war effort, and some had fighting in their area. When WWII started Africa found that not much had changed. However, as Africa gained its freedom and became self governing internal wars broke out between the different tribes. Well, you will have to read the book to find out how that turned out. This book covers all that and so much more. It all written in an easy to read and understand format that Captivating History is known for and as always they do a great job of explaining everything. This is a great book and recommend you giving it a read.

An Overview of an Oft-Overlooked History
Format: Kindle
Depending on your ethnicity, you may, or may not, know a lot about Africa. This book summarizes the Continent’s history, highlighting the major events and occurrences that contributed its current geopolitical state.
Africa today is made up of 54 countries, 2000 languages, 20% of the Earth's land mass, and 1.4 billion people. It therefore should play an important part in the World, today (which it does, but one that rarely makes the headlines in USA TV or newspaper coverage.) The Author covers, Slavery, European Colonization, Africa’s part in World Wars One & Two, and the various Religious histories going back to the time of Christ. Since the author is American, there is a portion devoted to the USA’s main relationships with different African Nations. All this culminates in a surveillance of the numerous African Civil Wars of the last 50 years leading to the reality of the current geopolitical scene. The section on Dictators and Revolutionaries is limited to one of each. I’m guessing there could have been more. Still, if you are looking for an overview of Africa as it is today and what contributed to its present situation, this is an excellent beginning point.
