Charger

I will make one soon and post it.

I understand the math calculation, and I did the math too, but when I put it to the test in real time, believe me it was a surprise for me too. I did not believe that it actually played for that much time. I don't know the factor, but I will make another test soon and notify you with the results. p.s. Maximum amp draw on maximum volume was only 1.5 A

Exactly, but also you will need a corespondent charger for lithium batteries.

Thanks!

I don't know about that contest, I will check it out. Thanks

Thank you. I am glad that was helpful. Hope to see your balance bike on instructables!

Thanks! You should try!
