The batteries are truly the heart of the EV conversion! Getting the right batteries for your ev conversion is essential and will ensure that you have many years of service from your converted vehicle. Deep cycle lead acid batteries, which can be further divided into flooded and sealed batteries, are used the most in electric vehicle conversions for the following reasons:
1. Deep cycle lead acid batteries are able to withstand repeated heavy discharging up to 30% of their capacity. They are able to withstand discharging to deeper levels for short periods of time, although this will affect their lifespan adversely.
2. Flooded Deep Cycle lead acid batteries are comparatively cheap, compared with other types of batteries and will last for quite a long time if you take care of them and do not discharge them beyond 30% of capacity and recharge them well when they are discharged.
3. Sealed Deep Cycle lead acid batteries are lighter than flooded batteries, which is beneficial when doing conversions with small vehicles and possibly some higher performance vehicles. They also do not need to only be placed upright and can therefore be placed into positions which are not possible with flooded lead acid batteries.
When considering which batteries to purchase for your electric vehicle conversion other factors which you should consider are:
1. The Life Cycle Cost
This is the initial cost of the batteries over the lifespan of the batteries, and can be a significant factor in determining which battery to use
2. Initial Cost Range
This is the initial cost of the batteries over the anticipated range, which can be used in conjunction with the life cycle cost in deciding which battery to use.
3. The Energy Density
This is amount of energy contained in a specific amount of the fuel source, that is the battery. Measured in watt-hours per pound, or watt-hours per kilogram it is a good way of determining which battery will best suit your conversion.
4. The amount of maintenance required.
Servicing an electric vehicle is not nearly as demanding as servicing a regular gas vehicle, however it is necessary to pay careful attention to the batteries in your electric vehicle as properly maintained batteries will last longer and therefore be cheaper per mile travelled.
As the batteries represent a considerable cost factor in your ev conversion you should carefully consider all these facts before choosing the batteries for your electric vehicle. And when you have made the decision and bought your battery set for your electric vehicle, be sure to take good care of them and then you will enjoy many miles of carefree and low cost traveling with your new electric vehicle.
