Discover the Future of Battery Technology with Weize 12V 50Ah LiFePO4 Batteries

Built to Outlast and Outperform:

  • Our 12V 50Ah LiFePO4 Batteries boast an impressive lifespan of over 2000 cycles at 100% capacity or a staggering 8000 cycles at 50% depth of discharge (as suggested).
  • In stark contrast, traditional lead-acid batteries typically last just about two years, equivalent to a mere 500 cycles at 50% discharge.
  • With a Weize LiFePO4 battery, you can enjoy more than five times the longevity, ultimately reducing your overall cost.

Smart Battery Management for Your Peace of Mind:

  • We've integrated a cutting-edge Battery Management System (BMS) into our batteries.
  • This BMS ensures your battery remains safe from overcharge and Discharge, Over-current, Short Circuiting, and extreme temperatures, all while enhancing overall performance and extending battery life.
  • The BMS even features an automatic circuit cutoff, with reactivation in just one second, eliminating the need for a higher voltage input to restart.

Lightweight and Versatile for All Your Needs:

  • LiFePO4 batteries are the future of energy storage, offering higher energy density and significantly reduced weight compared to traditional lead-acid batteries.
  • This makes them the ideal upgrade for any 12V Deep Cycle battery.
  • Our batteries are perfect for a wide range of applications, from Fish Finders and Ice Fishing to Camping, Solar Systems, Home Alarm Systems, and E-Scooters.
  • For optimal performance and safety, always charge the battery with a dedicated LITHIUM BATTERY CHARGER, and avoid connecting more than four batteries in series or parallel.

Safety First, Environmentally Friendly Always:

  • Crafted from 100% safe, non-toxic, non-hazardous materials, Weize LiFePO4 batteries prioritize safety.
  • Their superior chemical stability ensures they won't overheat, catch fire, or undergo thermal runaway even when punctured.
  • With no acid to worry about, you can confidently mount our batteries in any position.
  • For complete peace of mind, please consult our user manual before use, and don't hesitate to reach out if you have any questions about your battery. Your safety is our top priority.

12V 100AH group 31 - Super deal and outstanding customer service

Got 3 of these for my Ultrex trolling motor. They get heavy use year-round and have performed above expectations. Can fish several days on a single charge cycle. One of them started giving me problems so I contacted Weize through warranty claim. Sent a video and pics and they took immediate action. Sent me brand new battery in couple of days. So happy to get such outstanding service and support. Highly recommend.

50 Ah Lithium battery

I put the battery in my 2006 Prius and it appears to be working fine.
Voltage usually around 13.1 to 13.3 Volts according to display monitor in test mode, Car boots/starts right up and cars charger appears to work normally.
All and All, Great battery.

Weize Lithium Batteries are fabulous....

This is now my second lithium battery purchase from Weize. I own quite a few motorcycles and will eventually get as many as I can using their batteries. They are cheaper cost wise, have over double the CCA and weigh a fraction of AGM, lead acid and or GEL. I expect them too to last 4x longer. THANK YOU WEIZE ! Start making more motorcycle sizes please !
