Russia , officially the Russian Federation , is a transcontinental country in Eastern Europe and North Asia. At 17,125,200 square kilometres (6,612,100 sq mi), Russia is the largest country in the world by area, covering more than one-eighth of the Earth's inhabited land area and the ninth most populous, with about 146.77 million people as of 2019, excluding Crimea. About 77% of the population live in the western, European part of the country. Russia's capital, Moscow, is the largest metropolitan area in Europe proper and one of the largest cities in the world; other major cities include Saint Petersburg, Novosibirsk, Yekaterinburg and Nizhny Novgorod. It shares maritime borders with Japan by the Sea of Okhotsk and the U.S. state of Alaska across the Bering Strait. However, Russia recognises two more countries that border it, Abkhazia and South Ossetia.
Lithium ion electric-vehicle battery or traction battery is used to power the propulsion of battery electric vehicles. Vehicle batteries are usually a rechargeable battery which is also used in forklifts, electric golf carts, electric motorcycles, riding floor scrubbers, electric cars and other electric vehicles. Electric-vehicle batteries are designed to give power over sustained periods of time. Deep-cycle batteries are used instead of SLI batteries for these applications. Kingbo offers high performance lithium ion batteries for all types of electric vehicles.

Smaller and lighter available
A battery charger, or recharger, is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. The charging protocol (how much voltage or current for how long, and what to do when charging is complete, for instance) depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging (i.e., continued charging after the battery has been fully charged) and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. Simple chargers of this type must be manually disconnected at the end of the charge cycle, and some battery types absolutely require, or may use a timer, to cut off charging current at some fixed time, approximately when charging is complete. Other battery types cannot withstand over-charging, being damaged (reduced capacity, reduced lifetime), over heating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the state of charge, and cut off at the end of charge.
