Charging LiFeP04 battery banks. | DIY Solar Power Forum
To make the story short, charge 16s cell to 55.2v (3.45v) at CV-CC until the current taper to 6 or 7A and consider the battery pack fully charged. 1 hour of absorption phase at lower voltage is less stressful for the cells. Then you can just float the cells at 3.35v each or 53.6v for overall pack.

View more6 FAQs about [LiFePO4 battery pack not charging]
Why is my LiFePO4 battery not charging?
When the battery won’t be in use for an extended period, store it at around 50% charge in a cool, dry place. Avoid storing it in a fully charged or fully discharged state, as both can stress the battery over time. If you’ve gone through all troubleshooting steps and the LiFePO4 battery still won’t charge, it’s time to seek professional help.
How often should I charge my LiFePO4 battery?
Your battery can affect its performance from a charger, BMS failure, charging system, loose wires, or exposure to harsh temperatures. We always recommend having at least 50% charge in your battery and charging it every three months. In case you need to store it, read this article, How to store your LiFePO4 battery properly.
Does LiFePO4 battery have a long lifecycle?
Even though LiFePO4 batteries have a long lifecycle, some factors can contribute to reducing the battery´s life. We will mention the most common ones. Charging at the recommended voltage will make your battery charge quickly. However, it is common for people to charge at a higher voltage.
How do I Keep my LiFePO4 battery from overcharging?
Slow Charging: To remedy capacity loss, use a smart charger to slowly top off the battery. Monitor it closely for signs of overheating during the charging process. A Battery Management System (BMS) is critical for maintaining the health of a LiFePO4 battery by preventing overcharge, overdischarge, and cell imbalance.
Are all chargers compatible with LiFePO4 batteries?
Not all chargers are compatible with LiFePO4 batteries. Using the wrong type of charger or one with incorrect settings can prevent charging. Always ensure your charger is designed specifically for LiFePO4 batteries and that settings align with the battery’s requirements. Loose or Damaged Connections
How much voltage can A LiFePO4 pack charge?
I have a used 24v lifepo4 pack, and I can charge it up to any max voltage I want but it will quickly settle back to 26.5v (equivalent to 13.25v for you). This is not necessarily bad - while discharging, the pack stays in the 26.0 to 26.4 range for a long time (showing the famous flat discharge curve for lifepo4).
