Combat Lightsaber - Model Kanan

I love it I do have a question sometimes when turn it on it will keep announcing its battery percentage? I bought the correct charger and made sure i followed the instruction to a t but I'm worried theres an issue

Brilliant Saber and great customisation would recommend. Great customer service at the booth at Liverpool Comic Con. will buy from again

Good lightsaber, animation accurate and feels good to hold, settings are good
