Is it better to use lithium batteries or lead-acid batteries for two wheeled electric bicycles?

Should I choose lithium batteries or lead-acid batteries for two wheeled electric bicycles? The core depends on your actual usage needs and budget: if you pursue long battery life, strong power, fast charging experience, and are not sensitive to price, lithium batteries are the preferred choice; If high cost-effectiveness is emphasized, lead-acid batteries have more advantages for daily short distance commuting.

As a strong supplier of lithium battery solutions in the field of two wheel travel, the Liangneng Power editor provides the market with safe, reliable, and stable range lithium battery systems in accordance with automotive grade quality standards. The following provides a detailed comparison from the perspectives of core performance and product advantages

1、 Core Performance Comparison: Lithium Battery vs. Lead Acid Battery Performance
1. Battery life: Lithium batteries have better actual battery life
In theory, under the same capacity, voltage, power, and consistent operating conditions, the endurance of lithium batteries and lead-acid batteries is basically equivalent, and the endurance can be said to be almost the same.

But in practical usage scenarios, the endurance advantage of lithium batteries is very obvious:
The internal resistance of lithium batteries is much lower than that of lead-acid batteries. During operation, the internal resistance consumes less power and can convert more electricity into motor power, resulting in higher actual effective output power;
Under the same specifications, the weight of lithium batteries is only about one-third of that of lead-acid batteries. Lightweight vehicle body can reduce power loss and further convert it into range.

2. Service life: Lithium battery durability doubles
Lead acid battery: The cycle life is about 300 times or more. Calculated based on the frequency of most users charging once every 2-3 days, the actual service life is about 2 years. After two years, the battery will become less durable and I want to replace it with a lead-acid battery.
Lithium battery: The mainstream lithium iron phosphate battery has a cycle life of over 500 times, and some high-quality products can exceed 1000 times. Under the same charging frequency, the service life exceeds 3 years, and the long-term cost-effectiveness is higher.
