LifePO4 battery 12V 12Ah

LifePO4 Battery 12V 12Ah

Dreams come true.... 

Lithium batteries are finally available for our gate opener systems. An absolute Game Changer!

• Solar powered gate openers have typically relied on lead acid batteries for power storage. However, this is set to change as superior  battery options are becoming affordable. This development is promising, considering that 90% of issues with solar powered systems are somehow battery related. This will be the past as LifePO4 batteries offer significantly improved efficiency and longevity compared to lead acid batteries.

• We tested the smaller (10A) version of the LiFePo4 battery and the results were absolutely stunning. First we used 2 new, fully charged 12V 9Amp lead acid batteries wired in series to 24V, opening a 3.4m wooden farm gate 10 times daily. The batteries were exhousted after 7 days and 70 openings. We then repeated the test using 2 new 10Amp LiFePO4 batteries, opening the gate 15 times daily. After 10 days and 150 openings there is still power left for another 15-20 openings. 

  Here’s a clear comparison between lead-acid batteries and LiFePO4 (Lithium Iron Phosphate) batteries to explain why upgrading conventional acid batteries to lithium is a smart choice:

  1. Longer Lifespan

     • 12V 12Ah Lead-Acid: Typically lasts 300-700 cycles (1day=1cycle). total of 1-2 years (cost. $69)
     • 12V 12Ah LiFePO4: Can typically last 2,000-4,000 cycles. 5-10 years (cost ca. $99) 
     • Fewer replacements and significantly lower long-term costs, despite the initially higher price.

  2. Better Performance in Cold Weather

     • Lead-Acid: Struggles in cold temperatures, with 50% reduced capacity at 0 degree C.
     • LiFePO4: Performs better in cold conditions, with only 10% reduced capacity at 0 degree, making it more reliable for gate automation systems in winter.
     •  

  3. Deep Discharge Capability

     • Lead-Acid: Should only be discharged to about 50% to maintain a longer life.
     • LiFePO4: Can safely discharge up to 80-90% of its capacity without affecting its lifespan much.

  4. Weight and Size

     • Lead-Acid: Heavier for the same capacity.
     • LiFePO4: Much lighter and same sice, making installation easier, especially for DIY customers.

  5. Higher Efficiency

     • Lead-Acid: Loses efficiency faster and charges slower. 
     • LiFePO4: Has higher energy efficiency, with quicker charging times. 

  6. Safety

     • Lead-Acid: Can leak harmful acid and produce dangerous gases.
     • LiFePO4: Much safer, with no risk of leakage, and it’s thermally stable, meaning it’s less likely to overheat or catch fire.

  7. Environmentally Friendly

  • Lead-Acid: Contains toxic lead and acid that must be carefully recycled.
  • LiFePO4: Much more environmentally friendly, with no hazardous materials, and it has a longer lifespan, reducing waste.
  •  
  8. Limitations of LiFePO4 Batteries
     • LiFePO4 Batteries supply power in below zero temperature, no problem. However,  their inability to be charged below 0°C  is a limitation for outdoor use in regions that regularly experience sub-zero temperatures for longer than a day or two in a row (during day time) unless precautions are taken.
     • We can supply LiFePO4 battery systems designed for colder climates and they include on-board heating to mitigate this issue. The heating element kicks in during day time when temperatures drop below 0°C, warming the battery to a safe temperature before allowing charging. The power for the heating feature is provided by the solar panel and not by the battery itself. 

   

  Important: LiFePO4 batteries need a different charging voltage than lead acid batteries. You can't use your old charge controller or the battery will be damaged over time ($19 on Spezial)
