Frequently Asked Questions FAQ
Q1: How do I know if this battery is compatible with my sofa?
A: Please check the label on your original battery. The voltage V must match 25.9V. The capacity mAh/Ah can be equal to or
higher than the original for longer runtime. You are welcome to send us photos for confirmation.
Q2: What charger should I use with this battery pack?
A: We recommend using a dedicated 29.4V lithium-ion battery charger with CC/CV mode. The optimal charge current is 0.5C 1250mA
for this model. You can source a compatible charger from us.
Q3: Can I request a custom connector or different wire length?
A: Yes, absolutely. We specialize in custom battery solutions. Please inform us of your required connector type model/photos and
wire specifications during inquiry.
Q4: What is the difference between 7S1P and other configurations?
A: “7S1P” means 7 cells are connected in series to achieve the required voltage 3.7V * 7 = 25.9V, and these 7 cells are in a
single parallel group determining the capacity. This configuration is optimal for applications needing this specific voltage.
