The Dyness Powerbox Pro 10.24kWh LiFePO4 Battery has been pairing perfectly with my existing inverter. I went from 2 hours of backup to over 8 hours overnight. Battery health is still showing 100 percent after six months of daily cycling. PowerVault delivered to my area at a reasonable freight rate.

Upgraded from a 5kWh battery to the Dyness Powerbox Pro 10.24kWh and it has completely transformed how we use power. Running a home office and two teenagers doing online schooling from Nelspruit, the extra capacity means we get through any load shedding schedule without stress. The unit is compact for its size, installs cleanly and the BMS is rock solid. PowerVault delivered to Mpumalanga faster than expected.

The Powerbox Pro 10.24kWh is exactly what our smallholding needed. We run a borehole pump, chest freezer and lights through the night without coming close to draining the battery. Build quality is noticeably better than a competitor brand we previously tried. Very happy with the purchase and PowerVault’s after-sales communication was prompt every time I followed up.
