Frequently Asked Questions

What is an EVF battery and what applications is it designed for?

An EVF battery is a valve-regulated deep-cycle power battery built for electric vehicles such as e-rickshaws, golf carts, sightseeing cars and utility platforms. It stores and releases energy steadily over long working hours instead of delivering short cranking bursts.

What does the 3-hour rate (Ah/3hr) mean for EVF batteries?

The 3-hour rate is the capacity a battery delivers when discharged evenly over three hours. Electric vehicles draw continuous current while driving, so this rating reflects real driving conditions more closely than higher-rate figures and allows fair comparison between models.

Can EVF batteries be connected in series and parallel?

Yes. Connect batteries in series to reach the system voltage your vehicle controller requires, and in parallel to increase total capacity. Always use batteries of the same model, capacity and similar age in one pack so charge distribution stays balanced.

How long do EVF batteries last on a single charge?

Runtime depends on the load current, terrain, speed and battery capacity. A larger Ah rating extends the distance per charge. Plan routes around moderate discharge depths, because repeatedly draining the pack to empty shortens its overall cycle life.

What maintenance does an EVF battery require?

As a sealed VRLA product it needs no water refilling. Keep terminals clean and tight, recharge the pack promptly after each use, avoid long idle periods at low charge and store vehicles in a cool dry place to protect service life.
