What Is the Capacity of a 36V 80Ah Lithium RV Battery?

A 36V 80Ah lithium RV battery offers a total energy capacity of 2,880Wh (2.88kWh), calculated by multiplying 36 volts by 80 amp-hours. This battery delivers consistent, reliable power for RVs and golf carts, supporting extended use without performance degradation. Fasta Power’s advanced LiFePO4 technology ensures long cycle life, safety, and efficiency in every application.

How is the total capacity of a 36V 80Ah lithium battery calculated?

The total energy capacity is calculated by multiplying the nominal voltage (36V) by the amp-hour rating (80Ah):

Total Capacity (Wh)=36V×80Ah=2,880Wh

This means the battery can deliver 2,880 watts for one hour, or 288 watts for 10 hours, providing ample energy for most RV and golf cart needs.

Why is a 36V 80Ah lithium battery ideal for RV and golf cart use?

This battery size provides a balance of high energy density, lightweight design, and long runtime. It is a drop-in replacement for group 27 AGM, gel, or lead-acid batteries, offering twice the usable energy and half the weight. Fasta Power’s lithium batteries also support deep discharges, rapid charging, and minimal maintenance, making them perfect for mobile and recreational applications.

How does the built-in BMS enhance safety and performance?

An advanced Battery Management System (BMS) monitors voltage, current, and temperature, providing automatic protection against overcharging, deep discharge, short circuit, and overheating. Fasta Power’s BMS technology ensures safe operation, maximizes battery lifespan, and allows for Bluetooth or app-based monitoring in select models.

What is the expected lifespan and warranty of a 36V 80Ah lithium battery?

Most 36V 80Ah lithium batteries, including those from Fasta Power, are rated for 3,000–4,000+ cycles at 80% depth of discharge, translating to 8–10 years of typical use. Leading brands offer warranties from 5 to 10 years, ensuring long-term reliability and peace of mind for RV and golf cart owners.

Can a 36V 80Ah lithium battery be used in series or parallel configurations?

Yes, these batteries are modular and can be connected in series for higher voltage or in parallel for increased capacity. Fasta Power supports both configurations, allowing users to customize their energy storage for larger RVs, multi-battery golf carts, or solar backup systems.

How does a 36V 80Ah lithium battery compare to lead-acid alternatives?

Lithium batteries are up to 50% lighter, charge 3–5 times faster, and last 4–6 times longer than lead-acid. They provide more usable energy per charge, require zero maintenance, and have a much lower self-discharge rate. Fasta Power’s lithium solutions offer a significant upgrade in performance and total cost of ownership.

What certifications and protections should buyers expect?

Buyers should look for CE, UL, UN38.3, and IP67 certifications, as well as integrated BMS and optional Bluetooth monitoring. Fasta Power ensures every battery meets or exceeds international safety and quality standards.
