Yes, and the stackable battery should be stored in a cool, dry, ventilated environment, to avoid contact with fire and heat sources. Batteries should be stacked so that they're stable and won't be bumped, knocked over, or otherwise damaged. The best storage temperature is 25 ± 5 ℃, the best humidity is 60 ± 15%.

A 423-watt solar panel is required to charge a 200AH battery at a maximum rate of 30 amps. So four 100-watt solar panels can provide 400 watts, which is close to our goal of 423 watts.

10-25 years. The lifepo4 battery lifespan is related to the number of cycles and routine maintenance. Learn more about battery lifespan and how to look after it?.

The battery can be installed in any orientation, even upside down.

The storage temperature of conventional lifepo4 batteries should be within 18-25 degrees. If it is not used for a long time, it should be charged with 50%~80% of the electricity, and it should be taken out of the device and stored in a dry and cool environment, and cycle the battery at least once every 6 months. Know more about how to store your battery.

In daily use, lithium rack batteries are best charged to 90%. But in long-term storage applications, it can maintain a full cycle (charge and discharge) every 6-12 months, and then store and charge to only 50% SoC.
