Question about ION Audio Battery for Block Rocker Redisign and Tailgater

I don't know the name of the BlockRocker. But if this battery is listed here at Digitec as a spare part for the device, it should be the right one. In any case, I ordered this battery. It fitted my BlockRocker and could replace it 1:1. Side cover off, old battery out, new one in.... Everything perfect! Greetings Remi
