Founded in 2010, we are a "Green Energy Solution Service Provider" specializing in lithium rechargeable batteries, BMS, balancers, chargers and related products.

Main applications include electric bicycles, scooters, motorhomes, AGVs, solar/wind systems, energy storage systems, trucks and more.

Q1: Are busbars and screws included and free?

Yes, we ship the battery with busbar connectors and screws for free.

Q2: What is the lifecycle of the battery?

The typical estimated life of Lithium Iron Phosphate (LiFePO4) batteries is 5-8 years, or 2000 to 5000 charge cycles, depending on specific usage conditions such as depth of discharge, working current rate, working temperature, and whether a balancer is used.

Q3: Can I use a normal solar controller with LiFePO4 batteries?

We always recommend using LiFePO4/Lithium Ion solar controllers. Lead Acid solar controllers provide constant pulse current that might damage the PCB over time, compromising battery protection.

Q4: Can resellers get special pricing?

Yes, we support partners who share our values for creating a clean and green world with comprehensive service and pricing support.

Q5: Why can't I buy batteries directly from your store?

This typically occurs when we cannot provide accurate logistics pricing for your country. Please contact us directly for any requirements.

Q6: Why is there no tracking update after weeks of waiting?

This is normal - tracking numbers are not updated until packages arrive in your country. No tracking is available while packages are in transit by train.

Q7: Are the cells balanced before delivery?

Yes, we match and balance all cells to ensure internal resistance, voltage and capacity are completely matched and balanced before delivery.
