DETAILS
Overview
Charge your EP500 Pro or AC300 from a 12V or 24V battery
Clip the red and black clamps onto a 12V or 24V lead-acid battery and plug the MC4 ends into your BLUETTI EP500 Pro or AC300. The battery then charges the power station.
Handy in a long outage or off-grid when you have a spare lead-acid battery: a car, boat or deep-cycle battery becomes a top-up source for your BLUETTI.
Fits: BLUETTI EP500 Pro and AC300 (BLUETTI’s variant for these models). Other BLUETTI models use a different version of this cable.

Frequently asked questions
Which BLUETTI models does it work with?
This is BLUETTI’s EP500 Pro and AC300 version (MC4 plugs). Other models (AC200L/AC200P/AC200MAX, AC60, AC180, AC70, AC180T, Elite 200 V2, AC240, B210) need a different version.
Does it charge the lead-acid battery?
No. It works the other way: the lead-acid battery charges the BLUETTI power station.
What batteries can I use?
12V or 24V lead-acid batteries, as BLUETTI describes it.
Can I use it to connect solar panels?
No. It has battery clamps on one end, not solar connectors. Use your power station’s solar cable for panels.
Not sure which version you need?
