Eco-Worthy 12V 280Ah LiFePO4 Lithium Battery Voltage Drop out

[stubarnwell]

Hi,

I brought one of these, to use with our 3000watt inverter.
But the voltage keeps dropping down to about 10.5v. Even when the invertor was not running.
We have a 12v 80watt fridge.

I added 2 screen shots from someone else who has the battery and said when it gets to about 70% capacity, the voltage drops too low.

Any ideas? Eco Worthy wont accept a return as its over 30 days, but it seems the battery is not up to standard?

So just checking, those are not your screenshot, but you have the same issue?

How are you measuring your voltage?

I didn't think Lithium could go that low, not without the BMS shutting off.

What load are you running through the inverter? Are you using the full 3000w?

That's nearly 300amps from a 12/13v battery, what is the Ecoworthy rated for? It may not be capable of delivering that much current.

You wouldn't happen to have a solar panel too would you?

This is the battery you on about, I suspect your system is not set up right, or operator error. The battery is rock solid quality build for a decent price.
