Capacity Audit
We verify production capacity, assembly lines and test equipment against the volumes you are asking for.
Partner Factories
We do not own a factory. We qualify the ones that build your order.
How we qualify a factory
NewenGrid is a sourcing and export partner. Our job is to select, audit and manage the factories that make LiFePO4 portable power stations, so a buyer on the other side of the world does not have to fly to Guangdong to find out who is reliable.
Cell Sourcing
We trace where the LiFePO4 cells come from, and confirm the grade and the cycle-life claim behind them.
QC System
We review incoming inspection, in-line testing, ageing and final QC before we agree to quote from a line.
Included as standard
- Audit summary and capacity statement
- Full audit reports and disclosure under NDA
- Video walkthrough of the line that will build your order
- We do not publish factory names or addresses — your supply chain stays yours
If a factory cannot pass the audit, we do not quote from it, even when the price is better.
