FAQs
What is the actual capacity of this battery?
The EF-PK-B12-1 has a rated capacity of 1280Wh (12.8V / 100Ah). This is a true deep-cycle LiFePO₄ battery, so you can safely use most of its capacity without damaging it.
How many cycles can the battery handle?
It is rated for over 6000 charge cycles at 80% depth of discharge (DOD). This typically translates to 10+ years of regular use, making it one of the longest-lasting 12V batteries in its class.
Can I connect multiple batteries together?
Yes. You can connect them in parallel to increase capacity (up to 4 batteries recommended) or in series to increase voltage (up to 2 batteries for a 24V system). Always use identical batteries and follow the official wiring guidelines.
Does it come with a charger or solar controller?
No. The battery does not include a charger or solar charge controller. You will need a compatible 12V/14.4V LiFePO₄ charger or an MPPT solar charge controller that supports LiFePO₄ batteries for proper charging.
