48V (51.2V) 100Ah Golf Cart Lithium Battery (BMS 315A)

1. Battery Specifications

What is the voltage and capacity?
72V 50Ah lithium batteries provide stable power for golf carts, with 72 volts nominal voltage and 50 amp-hour capacity. This combination delivers extended range and consistent performance under load.

How many cycles does the battery have?
These batteries offer 2,000-3,000 cycles while maintaining 80% capacity, significantly outperforming lead-acid batteries that typically provide only 300-500 cycles.

What is the charging time required?
Full charging takes 2-4 hours with standard chargers, while fast chargers can reduce this to 1-2 hours due to lithium's superior charge acceptance rate.

2. Design and Advantages

Weight and dimensions of the battery?
Weighing approximately 25kg (55lbs), these batteries are 50% lighter than comparable lead-acid models, with compact dimensions that fit standard golf cart battery compartments.

Safety features included in design?
Built-in BMS protection prevents overcharging, overheating, and short circuits. LiFePO4 chemistry is inherently more stable and non-flammable compared to other battery types.

Advantages over lead-acid batteries?
Lithium offers longer lifespan, faster charging, and maintenance-free operation. They maintain consistent voltage output and aren't damaged by partial charging.

3. BMS Battery Features

What are key features of 315A BMS golf cart batteries?
315A BMS systems provide high discharge capability, cell balancing, and comprehensive protection. They enable faster acceleration and better hill-climbing performance.

Why choose China for wholesale golf cart battery suppliers?
Chinese manufacturers offer competitive pricing, custom solutions, and advanced technology. Many have extensive experience in lithium battery production and global export.

How does BMS enhance golf cart battery performance?
The BMS ensures optimal operation by monitoring cell voltages, temperatures, and current. It prevents damage from over-discharge and extends battery lifespan.

4. 51.2V Battery Systems

What are the technical specs of 51.2V golf cart batteries?
51.2V systems typically feature 100Ah capacity, 3,000+ cycle life, and compact designs. They're ideal for 48V golf cart systems needing higher performance.

Which Chinese factories produce high-capacity golf cart batteries?
Leading manufacturers include CATL, BYD, and EVE Energy, known for their quality control and innovative battery technologies.

How do 51.2V batteries improve golf cart performance?
These batteries provide higher efficiency and longer range compared to traditional 48V systems, with better voltage stability during acceleration.

5. 48V Battery Performance

What are key performance metrics for 48V golf cart batteries?
Important metrics include cycle life (2,000+), energy density, charge time (3-5 hours), and temperature range (-20°C to 60°C operation).

How to choose a 48V lithium battery for golf carts?
Consider capacity needs, BMS quality, warranty terms, and brand reputation. Ensure compatibility with your cart's voltage requirements.

What maintenance extends 48V lithium golf cart battery life?
Regular charging, avoiding full discharges, and temperature control significantly prolong battery life. No watering or equalization needed.

6. Pricing and Value

What factors affect 48V golf cart battery prices?
Key factors include battery capacity, BMS quality, cell type (LiFePO4 vs NMC), brand reputation, and order quantity.

How do brands compare in 48V golf cart battery costs?
Premium brands cost 20-30% more but offer better warranties and performance. Chinese OEMs provide excellent value for money.

Are lithium batteries cheaper than lead-acid long-term?
Despite higher upfront costs, lithium saves 40-60% long-term due to longer lifespan, no maintenance, and better efficiency.
