Easy to install, solidly built and works great. Price dropped $300 a week after receiving the battery and I received the difference within days.

I'm writing to tell you these batteries are great the plugs I think would work better if they were more 90 degree but still a great product at a great price and nice gift too

The BP3800 storage expansion battery is a simple plug-in solution to double the storage capacity of the Anker F3800. Set up with the power station and the app took only seconds and the performance has been outstanding. I like the ability to continue to expand my system if needed.

Easy to hook up

Worked perfectly, easy just plugged it in.
