Detailed Information

Briggs & Stratton’s PHI 3.8-MTM Battery utilizes the safest Lithium Ion chemistry available, Lithium Ferro Phosphate (LFP). No cobalt or explosive hazards that put customers at risk. By eliminating cobalt, the risk of thermal runaway, fire propagation, operating temperature constraints, and toxic coolants are reduced. When combined with our integrated high-performance Battery Management System (BMS), accessible 80A DC breaker On/Off switch and overcurrent protection (OCPD), the PHI 3.8-M Battery delivers safe, highly efficient and cost-effective service over the life of both residential and commercial installations, on or off-grid. Compatible with all industry-standard inverter charge controllers, the PHI 3.8-M Battery supports balance-of-system equipment and optimizes any power generation source – solar, wind, grid, generator – with scalable, on-demand energy storage solutions for critical back-up and daily savings on electricity bills.

Deployments: Commercial, Residential, Military, Humanitarian


  • Built-in accessible 80 Amp DC breaker On/Off switch - increases safety and simplifies installations
  • 48V LFP batteries with proprietary architecture and Battery Management System (BMS) - do not require ventilation, cooling or thermal regulation
  • Compatible with all industry standard inverter/charge controllers
  • Drop in replacement for lead acid
  • LFP is the safest, most environmentally benign Lithium Ion chemistry available - no cobalt, risk of thermal runaway or fire
  • No AC or toxic liquid cooling - negligible parasitic drain - long cycle life
  • Non-toxic and non-hazardous recyclable materials
