Description
After many years in the lithium battery industry, we recognised the challenges of maintaining consistent quality with imported batteries, often resulting in failures and costly repairs. To address this, we developed Sunnytech Solar Lithium Batteries. Our locally made LiFePO4 batteries are built with top tier, premium grade cells and a robust BMS, delivering superior performance and long-term reliability. With Bluetooth enabled monitoring via smartphone apps, our batteries provide intelligent, real time monitoring and management. Backed by responsive after-sales support, we are committed to delivering reliable, high-quality solutions you can trust.
Customized battery orders are available (12V to 48V, 50Ah to 600Ah). For details, contact sales@sunnytech.co.nz.
