If you own battery powered Somfy products and are tired of buying expensive Lithium batteries, you now have an option.
There is a seller on eBay that is manufacturing a longer wand. So instead of using 8 AA Lithium batteries, you can now use 10 AA NiMH rechargeable batteries.
Conversion is simple, just use the old end caps from your 8 cell wand, insert 10 NiMH's into your new wand, and plug-into your Somfy motor.
