A battery bank change is slated for the E-Z-GO 2FIVE LSV (Low Speed Electric Vehicle) scheduled for early spring 2014. This change in their standard 48 volt battery bank will take effect on March 1, 2014.
The new battery bank of the E-Z-GO 2FIVE will now feature a standard configuration of six 8 volt lead acid batteries. It will also feature a rust-free galvanized battery tray. The new battery bank configuration will replace the current four 12 volt batteries used in this platform. Sources confirm that this upgraded feature will not affect the price to the dealer or consumer
The six 8V battery configuration will increase the class leading range of the E-Z-GO 2Five by up to 18% compared to the standard four 12 volt batteries. Options will also be available to add a battery watering system.
We have previously touched on the “range wars” which currently rage through the electric golf cart and LSV industry. Range, the distance travelled on a single charge, is currently a standard measure of electric vehicle performance. Due to the fact AC power is much more efficient than DC, this drive system is used in both the E-Z-GO RXV and 2FIVE for extended range benefits.
Obviously, many factors play a part in the overall range of any electric vehicle including tire size, drive system, battery configuration, type of batteries, load on vehicle, terrain and many others. For the purpose of this discussion we’ll only cover how the battery bank configuration affects range as related to this example.
When using lead acid batteries in series for the battery bank in a golf cart or LSV, many different configurations can be used, all of which produce different results. Let’s use the 48 volt configuration as an example. To achieve 48 volts of usable power in your battery bank, there are three common configurations. The first is a battery bank comprised of four 12 volt batteries. The second is a battery bank comprised of six 8 volt batteries. And, the third is to use eight 6 volt batteries. Of these configurations, the battery bank of four 12 volt batteries will have the least range, the bank with six 8 volts will have slightly further range, and the battery bank comprised of eight 6 volts will have the greatest range of the three. Of course, this scenario assumes all else is equal; load, cart specs, terrain, etc.
The increases in range above are gained through adding more active material to the bank. In this case, the active material is lead. The more lead which is present in your battery bank, the greater your range and the greater distance you can travel per charge. At some point, on high voltage applications, weight would become a factor, but for the lower voltages commonly used with golf carts and LSV’s (48V & 72V), the benefits of having more lead for range are greater than the disadvantages of adding more batteries and more weight.
