About Ana

Ana is a research chemist and our solar batteries expert. She holds a bachelor’s degree in chemistry and has a strong background in environmental chemistry.

As a solar energy enthusiast, she is deeply interested in how chemistry can be applied in the development and improvement of solar technologies, especially when it comes to batteries.

During her studies, her research topics included the use of amines and other technologies for carbon capture and storage, peptide synthesis, and in silico prediction of peptide activity.

After graduating, she moved abroad and worked for a biotechnology company. As a chemist, she worked in the research and development department and has experience with the optimization of organic reactions and the development and validation of purification methods for scale-up production.

Currently, Ana’s main fields of interest are electrochemistry and solar technologies. She’s passionate about learning the different alternatives for solar energy storage – the ones already available and the ones currently being developed – and loves sharing her knowledge on this topic with our readers.

You can find most of her articles in the solar battery and solar generator sections. She occasionally writes articles related to electric vehicles and solar panels.

  1. Hi Valentin,
    Thanks for the compliment! We really appreciate your comment 🙂

    Regarding your question: As you can see, I didn’t write specific numbers for each battery, I used a relatively wide range for their life cycle.
    And that’s because I didn’t use one single source to find the data I used to build the chart. I gathered information from several sources/studies. As you know, different sources/studies will show you different information regarding cycle life (while one study can show that a NMC battery performs 1500 cycles, another one can say it performs 2000 cycles, for example). That’s normal, because cycle life depends on several factors (internal and external), so these numbers can vary greatly.
    With that said, I’ll leave you a few links that I used while doing research for the article. Hope it helps!

  2. Hi James,
    Thanks for the comment!

    We’re sorry to hear that you’re having trouble with your supplier, but we hope your problems will be solved shortly. Good things take time!

  3. Hey Josh, 
    Thanks for reaching out to us!

    You’re right, depending on your power needs, a 60A BMS can be small for a 200 Ah LiFePO4 battery. 

    With your current BMS, the maximum continuous discharge current is 60 A (0.3 C rate) before the short circuit protection kicks in and cuts off power, which is done to protect your battery.

    However, LiFePO4 can be discharged at currents of up to 3C (although in most cases, a discharge current of up to 1C is recommended for prolonged use). 

    Therefore, if you’re planning on drawing more than 60A (768W) from your battery, or planning on charging it at a rate higher than 0.3C, then you’ll need a bigger BMS. 

    For your case, considering a discharge rate of up to 1C, a 200 A BMS would be recommended, such as the DALY Smart BMS 4S 12V 200A LiFePO4 or the RadioB Smart BMS 4S 12V 200A LiFePO4 BMS (both come with Bluetooth).

    We hope this helps!

  4. Hi Mark,
    Thanks for you comment.
    You’re right, the Fe in LiFePO4 stands for Iron. However, ‘Lithium Ion‘ refers to a type of rechargeable battery composed of cells in which lithium ions (ions are electrically charged atoms/ molecules) move between the electrodes. You can find Lithium Ion Batteries in several different chemistries. One of the most common chemistries of lithium ion batteries is the LiFePO4, in which one of the electrodes is made of lithium iron phosphate. Other examples of Lithium ion batteries are Lithium Cobalt Oxide (LiCoO2) and Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2). If you’re interested in learning more about lithium ion batteries, here are two interesting articles:

  5. Hi Dalton,

    We completely agree. NOCO offers some of the safest and most advanced battery chargers on the market, especially when it comes to starting or charging a dead battery.

    Thank you for your comment!
