  • SAFETY - PowerTex LiFePO4 Lithium Iron Phosphate Batteries come standard with a built-in BMS (Battery Management System) that protects it from the most common causes of battery failure like overcharge, deep discharge, overloading, overheating. It essentially regulates the amount of power coming out of the battery to protect the Lithium cells, equipment and user.
  • SAVING MONEY - Our Drop-In LFP Lithium Iron Phosphate Batteries have 10X the lifespan of the average sealed lead acid battery and can be charged/discharged repeatedly. With exceptional longevity and low $ cost per cycle, our LFP batteries end up costing the user less than SLA over time.
  • LIGHTWEIGHT - Our LiFePO4 battery is only a 1/3 of the weight of Lead Acid batteries, which makes it the ideal choice for RV, campers, trolling motors, marine, golf carts, off grid & More!
  • EFFICIENT - Lithium Iron Phosphate battery’s flat discharge curve holds above 24V for up to 90% of its capacity usage providing astronomical boosts in run-time compared to only 50% in Lead Acid.
  • WARRANTY - We stand by and believe in our products and think you should too! That's why we test all batteries before shipping and offer a 3 Year warranty.
  • CHARGING - A LiFePO4 charger is highly recommended since SLA chargers might not reach the optimal 28.8V - 29.0V LiFePO4 charging voltage. This might result in the LFP battery never reaching it's full charge and thus lowering the performance.
