Solid BThey have a solid build and nice capacity. You need to make them useable and chargeable without the base though. It would be nice to be able to use and charge them separately when you're not needing the full power of the 2 together.

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

Expand!!
Easy to expand kWh of F3800. Just plug it in to the main unit and turn the main on. Great example of plug ‘n play. But it is really heavy. I had to get help to stack it on top of my F3800.

Very happy.
We have peace of mind knowing that when we loose electricity, we will have power.
The setup was simple and performs as advertised

Easy to set up.
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.
