The Briggs & Stratton PHI batteries use Lithium Ferro Phosphate (LFP) chemistry and run cooler, meaning they’re safer, more reliable and have a longer lifespan with 10,000 cycles at 80% DoD (depth of discharge). The batteries, which are cobalt-free, can easily be scaled to increase capacity to 294kWh and they provide integrated solutions that are compatible with other brands. They can also replace older lead-acid batteries and are well suited for flexibility in off-grid applications. PHI batteries from Briggs & Stratton Energy Solutions all come with a 10-year limited warranty while AmpliPHI and SimpliPHI® batteries come with an industry leading 15-year limited warranty.
