High quality, sits nicely on top of my F3800 and adds another 3.8kw of power!

We have peace of mind knowing that when we loose electricity, we will have power.

The setup was simple and performs as advertised

Love the plug and play of the F3800 and the BP3800 expansion batteries. Just plug it in and the F3800 handles it all seamlessly. Easy to use in my RV for when the power goes out.

I got this second BP3800 to raise my stored wattage to 11,400 to ensure a longer period between generator runs. Power outages have lasted up to 11 days here and we get tired of the noise especially at night. I will charge my Anker Solix batteries while running the house on generator and then switch to quiet battery power over night.

The BP3800 was so easy to install. Just plug the cable from the F3800 and into the BP3800 and press the power button. I could then see in the Anker app that my F3800 shows the connected BP3800 and expanded capacity.

Overall this is Home Battery Power solution I've been waiting for. I can expand the system as necessary by myself. No need for Electricians or battery installers to increase capacity.
