Who
Daniel Puratich idea
Tim Gu looking into it
What
Take in 12V and output 24V
For powering our 24V battery charger
would be massive help at comp and flight tests to be able to charge faster
Supply enough power for the charger
if the current is really high then this project is going to be waaay out of our skill range
Why
We have 12V server PSUs that are CSA approved
We get more power capability out of the charger at 24V
we could also just buy this? not sure if it maths out.
Details
Battery charger: HotA F6 Quad Battery Charger (4 x 15 A)
 |  |
|---|
1000 W output power limit across the 4 channels, with max current 4 x 15 A.
PSU:
We’re using the PSU that is connected to our usual battery charger.
What is the output current/power rating?
Whichever convertor we choose should be able to handle the same amount of power that the PSU outputs
COTS options:
AliExpress seems to have the most amount of options and is well priced (but might be a bit sketchy?
Couldn’t really find anything good on Amazon or Facebook Marketplace
