Customer Reviews
i have a nice memory of our meeting in Shenzhn with Deligreen Mandy and a beautiful impression of your growing company.We both are straightforward and honest people and this is the most important value,so i am sure we can

—— Angelo from Italy

I am sure we can happily work together we should easily find a way to do.Money are important but aren't the most important part.

—— Angelo from Italy

Deligreen is the partner that i have replied one for years. Some other suppliers change sales quickly but Deligreen not.

—— Bonnett from USA

i have used the batteries for 9 years from Deligreen. Amazing!

—— Phil, LA

COVID19 made something more difficult. we need the balancers urgently.Thanks for the Deligreen team's effort. We receive the balancers on time and no delay for our project. Thank godness

12V lead-acid batteries(AGM) are widely used in RVs, trailers, and trucks as power sources for lighting, water pumps, fans, refrigerators (12V models), air conditioners, and other onboard electrical appliances.Due to its low cost, adaptability to a wide temperature range, simple maintenance, and compatibility with vehicle 12V circuits, it is widely welcomed by car owners and manufacturers.

 

However, lead-acid batteries have the disadvantages of large volume, low energy density, small capacity, and few cycles. A 12V lithium battery can compensate for these disadvantages. Lithium batteries are increasingly being used in 12V power supplies for RVs and trucks.

 

Here’s a clear comparison between 12V Lead-Acid Batteries and 12V Lithium Batteries (e.g., LiFePO₄) in table format:

Feature 12V Lead-Acid Battery 12V Lithium Battery (LiFePO₄)
Energy Density Low (~30-50 Wh/kg) High (~90-160 Wh/kg)
Weight Heavy (e.g., 20-30 kg for 100Ah) Light (e.g., 10-15 kg for 100Ah)
Cycle Life 300-500 cycles (50% DoD) 2000-5000 cycles (80-90% DoD)
Depth of Discharge (DoD) 50% recommended (deep-cycle: 80%) 80-100% safe
Charging Speed Slow (5-8 hours) Fast (1-3 hours, higher charge current)
Efficiency 70-85% 95-98%
Voltage Stability Drops under load Stable voltage until depleted
Maintenance Requires watering (flooded) or AGM sealed Maintenance-free
Temperature Tolerance Performance drops below 0°C or above 40°C Wider range (-20°C to 60°C, but may need heating at low temps)
Cost Low initial cost ($100-$300 for 100Ah) High initial cost ($400-$1000 for 100Ah)
Lifespan 3-5 years 8-15 years
Safety Risk of acid leaks, venting gases (H₂) Safer (no leaks, BMS protection)
Environmental Impact Toxic (lead, acid), recycling required Cleaner, but recycling infrastructure developing
Common Uses Car/RV starter batteries, backup power RVs, solar storage, marine, high-performance
