  • GRADE A LIFEPO4 CELLS - Powertex LiFePO4 Lithium Iron Phosphate batteries are unlike other batteries, we provide the highest level of quality and reliability. Our cells have excellent power density & thermal stability making the battery more durable and longer lasting. All batteries are UN38.3 certified.
  • BATTERY MANAGEMENT SYSTEM ‚Äď A must in Lithium Iron Phosphate batteries, Powertex LiFePO4 batteries feature an internal BMS. It ensures all cells within the battery have the same state of charge, meaning each cell has the same energy. This way the battery lasts longer because you do not get one weak or dead cell. The BMS also has additional safety measures.
  • LONGER LIFESPAN ‚Äď A charge cycle is described as the battery being discharged from 100% down and back up. Powertex LiFePO4 Batteries provide up to 5,000 cycles if used accordingly. 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.
  • EXTREMELY LIGHTWEIGHT ‚Äď Powertex‚Äôs LiFePO4 YTX7A-BS replacement battery weighs in at¬†1.4 lbs compared to the standard lead acid equivalent which weighs a whopping¬†5 lbs. This makes it the ideal choice for motorcycles that need weight reduction.
  • EFFICIENT ‚Äď A Powertex Battery can still start a bike at 50% capacity due to its high platform voltage. Additionally, our LiFePO4 battery‚Äôs flat discharge curve holds above 12V for up 90% of its capacity usage providing astronomical boosts in run-time compared only 50%in Lead Acid.

PowerTex Batterie YTX7A-BS LiFePO4

Battery is light and well made. Installed in my Champion generator. Generator started five times in succession with no issues. Durability and longevity are my objectives, I will update as we travel trough the years.

Great Battery and excellent fast shipping at a great price

Received my battery in two days, properly packaged in perfect condition. Put it on a little Noco Genius 1 battery charger designed for use with lithium batteries. Charged the PowerTex overnight for good measure, voltage was 15 volts after charging, the ambient temperature it was charged at was 70 to 75 F. Battery performs flawlessly and spun my engine faster and stronger than the lead Acid battery it replaced. Next battery I have to buy will definitely be purchased from the fine folks at PowerTex.
