A) On average, an EV with the older lead acid batteries or valve-regulated lead–acid battery packs or the new Lithium Ion packs will charge fully overnight.  The Mahindra e2o EV hatchback charges in 5 hours.  The Hero Electric E Sprint electric scooter charges in 8 hours.
With Lead Acid batteries, 70% of the charging is done in the first 40% of charging time. The rest is the “topping up” stage of the charging process. Technology is changing constantly however, and with new battery technology comes faster charging times.  
A possible solution – the ability to completely charge an electric car in a matter of 20 minutes. This is made possible thanks to the utilization of a single standardized connector which will accept DC fast charging.  
Speak with your EV manufacturer if there is a provision for DC fast charging in your EV.

Not for many years. Mahindra offer warranties covering 5 years of driving on the lithium-ion batteries in the e2o.
Reva users have used batteries for more than 3 years.
One simple technique that could be used to pay for the battery is to start an Recurring Deposit of Rs2000 per month for 3 years or more.
Liquidate the RD after 3-4 years whenever the need arises to change the battery. Thus bank interest accumulation can partly help you fund your shiny new battery pack!

Any battery-operated vehicle which has power less than 250W and speed limit not more than 25kmph such electric scooter are exempted from RTO and these electric scooters don't require a licence in India.

It has a load capacity of 150kg, which is equal to the carrying capacity of any petrol vehicle.

Amount of electricity consumed by an EV is dependent on voltage (V) and current (Ah) values.

For instance, if the battery is rated as 72V 50Ah they 72VX50Ah=3600W as Power= Voltage x Current.

So it is taking about 1.34 KW. Depending on electricity tariff rates in your region i.e  Rs 6 for 1 Unit consumption.

So the approx electricity consumption for the battery would be approx 3.6KW x 6 = Rs 21.6 = Rs. 22.

Hence Electric bike are highly economical as compared to their counterpart Petrol Vehicles. It can go for 0.22 paisa per km.

In India, we have a present temperature of around 30-40 degree C thus VRLA battery with 300-350 life cycle lasts around 1-2 years whereas lithium-ion with 1500 lifecycle last around 3 - 4 years.

• They are highly economical. Within 1.5 years you can actually save the money equivalent to the amount of electric scooter to the amount you will spend on petrol fuel.
• Electric Scooter are extremely low maintenance scooters. Hence running cost reduces further.
• You will undoubtedly help save the environment as there is air or noise pollution made by Electric Scooters. Hence contributing to #Swachha Bharat Abhiyan

This bike is the safest bike it won’t harm, as the battery pack has fire-retardant FRP which will withstand any fire impact.
