FAQs for 12V 18Ah battery box
The usage time of a 12V 18Ah battery depends on the power of the load. For example, if the power of the device is 10W, then (12V * 18Ah) / 10W = 21.6H.
Make sure to use a charger designed for LiFePO4 batteries, the output voltage should be 14.4V.
If the charger is adjustable, select 3A~5A charging current.
Connect the charger and start charging.
Once fully charged, disconnect the charger first, then remove the clamp.
The terminal of our 12.8V 18Ah lifepo4 is F2 (plug-in type).
You need to use a 12V charger designed specifically for lithium iron phosphate (LiFePO4) batteries. Do not use a regular lead-acid battery charger as this may damage the battery.
Our Hongyitai lithium iron phosphate battery supports a maximum of 16 strings and 4 parallels.
