After over six years in the lithium battery industry, we recognized the difficulty in ensuring consistent quality with imported batteries, often leading to failures and high repair costs. To address this, we created Sunnytech Solar Lithium Batteries. Our locally made LiFePO4 batteries use premium CATL cells and robust BMS control systems, ensuring superior performance. With Bluetooth-enabled monitoring via smartphone apps, our batteries offer intelligent, real-time management. Backed by our efficient after-sales support, we are committed to delivering reliable, high-quality solutions to our customers.

Customized battery orders are available (12V to 48V, 50Ah to 300Ah). For details, contact mailto:sales@sunnytech.co.nz.
