Product & OEM/ODM FAQ
What is the MOQ for the 12V 300Ah battery and do you support trial orders?
Standard OEM MOQ starts at 100 units; flexible trial orders may be available for qualified new brand partners.
How much energy does this battery store?
The 12.8V 300Ah battery stores 3.84kWh of energy and supports up to 200A charge and 200A discharge, ideal for high-capacity solar and off-grid energy storage systems.
What is the cycle life of the 300Ah model?
It delivers over 4,000 cycles at 80% DoD with 80%+ remaining capacity — a service life of 10+ years under normal daily cycling, with no memory effect.
Can this battery be used for solar self-consumption and backup?
Yes. With 200A charge capability, it pairs well with solar charge controllers for daily storage, and the smart BMS + Bluetooth app gives you real-time SOC, voltage and temperature monitoring.
What certifications are available for export?
The battery is compliant with ISO 9001, BSCI, CE, FCC, UL, KC, RoHS, UN38.3, MSDS, and PSE and shipped with UN38.3 and MSDS documentation from our ISO 9001 and BSCI certified factory.
What should I confirm before sampling?
Confirm installation space, continuous load, charging profile, series/parallel limits and any monitoring or communication requirements before approving a battery. Share branding, packaging and any engineering changes in your RFQ.
How long do samples and production take?
For standard-platform projects, allow approximately 15 days for samples and approximately 45 days for mass production after specifications and commercial terms are approved. New tooling, engineering changes, testing, certification work and material availability can change the schedule; the confirmed quotation and production plan control.
