12V200AH

Q1: How do I know if the battery is fully charged?

A: Meet the charging voltage range required by the battery (14.2V-14.6V), measure the voltage of the battery 1 hour after the charger shows that the charging is completed and the power is disconnected. If it is between 13.4V-13.8V, it means that it is fully charged, otherwise continue charging.

Q2: How can I use it to make the battery last longer?

Charging with a current of no more than 0.5C (C indicates battery capacity), and retain 10% of the power when the battery is discharged. Use the battery in the temperature range of – 4 ° F ~ 140 ° F.

Q3: How many solar panels do I need to use to provide the appliances in my RV for use at night?

A 12V 200ah LiFePO4 battery can store 2560Wh of electricity. Generally speaking, solar panels can effectively illuminate for 5 hours on sunny days, and the conversion rate is about 85%. For example, a solar panel with a total of 600 watts can store electricity for the battery after 5 hours of sunshine: 600W * 0.85 * 5h = 2550Wh, which can almost completely fill the battery.

Q4: Do these batteries have low temp cut-off or low temp protection function?

A: The batteries we are currently selling do not have the function of low-temp cut-off or low-temp protection, but these cells are civil grade A low-temp batteries. When the temperature is below 32 ℉, the cells will slowly enter dormancy with the decrease of temperature, and the lithium ion activity will be reduced, so as to protect the cells from low temperature damage.
