somfy Rechargeable Battery Pack 3-Pack with Charger - Power Blinds, Shades, Curtains - Long-Lasting, Easy Install - Includes Wall Mount Clips - Supports Multiple Motors - #9021217, #9025166

Easy to install

As expected and works perfect.

The Somfy rechargeable battery pack does not work on Bali motorized shades. It does have proper male usb connector.

I have the 8xAA battery wand and the alkaline batteries are awfully underpowered for the motor. The Lithium Ion pack makes the shades much snappier and the the operation is quick.The light on the charger adapter is red while charging and turns green when finished. Takes 6 hours max.

Poor instructions on how long it takes to recharge. Written instructions very poor

Have a Somfy shade that just sucks up batteries and decided to give this a shot. Worked great, and an easy install. As my other Somfy shades' batteries die, I'll be replacing them with these also. At the current price of Lithium AAs, they will pay for themselves in no more than 18 months.

I have 8 battery operated blinds. Each one takes 8 batteries per wand. You can imagine the ordeal and cost of replacing 64 expensive AA batteries. I've used alkaline and lithium, both have short lifespans. In addition, with the old battery wands, you must disconnect the wand to change out batteries and that sometimes erases programming, which is not so easy to restore. With this setup you can charge the battery pack without disconnecting. As the original batteries die, I'm replacing the with the Somfy Lithium Ion Battery Pack. I'm on my 3rd one and so far so good. I figure the packs will pay for themselves after only 2-3 changes. And you really only need one charger. BTW, although it says the charger has a 6' cord, the one I got is more like 12', so you don't need to buy the optional extension.

The product was as described but took a couple of weeks to be shipped. Once shipped, I got it intact and quickly. I would find a different seller for my next order.
