State of Charge
The lifepo4 battery capacity could be roughly estimated by its voltage. As there are subtle differences in the voltage of each battery, the parameters below are for reference only.
The voltage needs to be tested at rest (with zero current) after 30 mins of disconnecting from charger & loads.
Capacity Voltage
100%-13.5V // 99%-13.4V // 90%-13.3V // 70%-13.2V // 40%-13.1V // 30%-13.0V // 20% -12.9V // 10%-12.8V // 1%-10.8V (recommend low voltage disconnect voltage) // 0%-9.5V
Normally, the battery will be at 100% capacity when its rest voltage drops and remains at 13.4-13.6V.
Tips: Recommend to charge with Redodo LifePO4 Charger for longer use.

What is Like New Batteries
Batteries that have been opened out of the box but have never been used, or batteries that have been used for 3-5 days with minor cosmetic scratches and no issues with battery performance. Like New batteries are more affordable but come with the same 5 year warranty as new batteries.
