Frequently Asked Questions
How do I judge what material my battery is?
Please check the battery body. If the normal voltage shows as 3.2V, it is LiFePo4. If it shows 3.6V or 3.7V, it is a Li-ion or Li-polymer battery.
How is product quality guaranteed?
We ensure quality through mandatory pre-production samples before mass production and a final 100% inspection before shipment.
What products can you provide?
We offer Battery Pack BMS, LiFePo4/Lithium Ion PCM, Protection Circuit Boards (PCB), and complete LiFePo4/Lithium Ion Battery Packs.
Why choose our BMS solutions over other suppliers?
Our systems are backed by advanced production equipment, a scientific quality management system, and a deep philosophy focused on quality and environmental sustainability.
What payment and delivery terms are accepted?
We accept FOB and EXW delivery terms. Payments can be made via T/T, PayPal, Western Union, or Cash in USD or CNY.
How can I get a recommendation for my specific project?
Simply provide details regarding the relative voltage, number of cells, and current (Amps) or the equipment being used, and we will recommend the most suitable product.
