Electric vehicle is a major demand in the automobile industry due to its impressive competitive behavior with internal combustion engines. Batteries are the key component in any electric vehicle. More or less they are the heart of the vehicle. Managing the battery system can effectively boost the overall development of an electric vehicle significantly. Our survey and review briefs the current scenario of the batteries that is Lithium-ion batteries which is ruling the era now. Nevertheless there are better options compared to lithium – ion batteries due to its variable drawbacks. Flow batteries are a worth competitor for Li-ion battery as they give lot of benefits compared to the present conventional batteries. The paper also describes the benefits and advancement of batteries for high voltage applications. Our paper analysis describes the replacements of Li-ion with Vanadium redox flow batteries and a comparison of the same to justify the reason to adopt flow batteries. The flow batteries will remarkably improve the electric vehicles
