  • MORE POWER¬†- The rated voltage of our batteries is about 0.8V higher than a lead-acid battery, meaning the battery has more discharge power. As a result, it can improve the combustion¬†efficiency of the fuel in the engine cylinder. So when using this battery you may feel the car start faster, has lower fuel consumption, lighter throttle,¬†more responsive engine and more power!
  • LIGHTWEIGHT¬†‚Äď Powertex‚Äôs LiFePO4¬†BCI Group 51 battery weighs in at 10.6 lbs compared to the standard lead acid equivalent which weighs a whopping 27.8 lbs.¬†
  • GRADE A CELLS¬†- Powertex LiFePO4 Lithium Iron Phosphate car batteries provide the highest level of quality and reliability. Don't be fooled by the competition, our cells are UL certified. Our batteries UN38.3 & RoHs certified.¬†
  • LONGEVITY¬†‚Äď Powertex LiFePO4 automotive batteries provide¬†more than 2,000 cycles at 80% DOD (depth of discharge). This is compared to a lead acid battery that only offers 200 ~ 500 cycles. As a result, our lithium iron phosphate batteries have a lifespan of about 5 to 10 years.
  • 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 14.4V-15V LiFePO4 charging voltage. This might¬†result in the¬†LFP battery never reaching it's full charge and thus lowering the performance.

Battery Features

  • Super high-rate Lithium Iron Phosphate battery technology, instant discharge rate exceeding 20C.
  • Superior performance at low temperatures to similar products on the market, more suitable for low temperature environments.
  • High energy density,¬†a third of the weight of a lead-acid battery.
  • Low self-discharge rate, can be used after one year of storage¬† at normal temperatures.
  • With three times the service life of SLA batteries, the average battery life is 6-10 years.
  • Built-in charge balance guard plate to ensure all cells within the battery are properly balanced inside the battery at all times.
  • Operates in all positions, no need to worry about leaking.
  • No corrosive liquid, free of toxic heavy metals, green and environmentally friendly.
  • Cylindrical core and energy storage spot welding technology brings good safety.
