Hi guys, absolute amateur here.
I'm building my second boombox this lockdown and have struck a few problems.
I'm using a diy 10s 18650 36v battery which when fully charged reads 42 v (I did not realise this was the case. Thoight it was 36v and below)
The amplifier I have brought is a wondom amplifier rated at a maximum input voltage of 39 or minimum around 24v (36 is the ideal voltage).
Is there a way that I can reduce the output of the battery pack to 39v or less? So far I have been researching buck down converters but haven't found any that go above 40v .
Any ideas are welcome
Thanks in advance
Charlie

A couple of diodes in series will each knock down the voltage ~0.65V
Be extremely careful with 18650's. Careful in storage, handling and application. They can kill you.
