The truth about what is happening right now in China that affects just about all lithium phosphate batteries you purchase now!

Our batteries and what you get elsewhere!

Our Platinum Off Grid Battery 16KW
tested capacity 17KW

The best battery you can buy to power your
Off Grid home! You can link up to 32 together that's half a megawatt of stored energy 😲
Only available at Port Stephens BMS
Built with Brand New Grade A 4th generation chemistry cells you cannot get anywhere else ! 6 years warranty on our cells!

As the prices in China have skyrocketed on the latest Lifepo4 cell technology because of a newly introduced tax and material sourcing.
This has forced the market to source
B & C grade EV Cells from Chinese Auto manufacturers and the surplus of manufacturing so many electric cars, many New Battery brands now surfaced with smart marketing collaborating between American and Chinese partnerships they are all back doors for 2nd rate EV cells that never quite cut it to be in an EV.
So they repurpose them for the domestic market and obviously they get them much cheaper.
They all claim to be using a grade A with huge capacities by changing QR codes and using all sorts of tricks to Fool you 🤣
