    I have a 20s with a bad battery U tube shows you how to change the battery and you can buy one on amazon. you would think that sena itself would operate a repair facility. Lousy customer service they gave me part number of battery and said where i buy the battery they should be able to change it. There delusional you have to do it yourself. I spent almost $ 800.00 for two units and they tell me to upgrade to a newer model.

    You can buy a battery for the 20S in Amazon but with the wrong connector.

    Sena doesn't sell a replacement battery with the right connector.

    Agree, lousy customer service.
