Authorized distributor for EV, CATL, LISHEN, CALB, and REPT batteries. Every single cell is guaranteed to be 100% original, Grade A, and brand new.
100% testing of cell voltage and internal resistance (IR) to ensure precise matching before shipment. Video validation and third-party QC welcome.
Full usage support, technical assistance, and after-sales coverage for confirmed manufacturing defects to secure your investment.
Experienced electrical and structural design engineers provide flexible custom battery pack designs tailored to your sizing and capacity requirements.
You must ensure that all battery cells are balanced to the exact same voltage before assembling them. Improper assembly, incorrect wiring, or lack of proper balancing that leads to damage is not covered under our policy. Please inspect and test voltage and internal resistance upon receiving the cells.
Yes, we conduct strict quality tests on every battery cell. Our testing standard guarantees a capacity test margin of error under 2% (over nominal capacity), voltage deviation under 0.01V, and internal resistance deviation under 0.05mΩ.
Yes. Standard cells are supplied with high-quality nickel-plated copper bus bars and steel bolts or studs for free. Typically, one battery cell comes with one bus bar and two bolts or studs.
Returns and refunds will not be granted if: (1) Assembly errors occur, such as a burned protection board due to incorrect wiring, charger failure, or unbalanced configuration. (2) Charging without a protection BMS leads to cell bulging, swelling, or damage caused by welding.
Please contact us immediately with clear photographic or video proof. If the shipment is verified to be lost or severely damaged to the point where it cannot be used safely, we will coordinate with you to arrange a replacement, reshipment, or product cost refund.
These cells are factory prototypes without an integrated protection board (BMS). You must select and install a compatible BMS to manage charging, discharging, and balancing safely before deployment.
