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.
