Happy Breffast!
This charger, 20A 1-8S balance charger:
8S balance leads (no, you don't need 10, and you'd only use 5 of the 9 wires for 4S):
and XT-60 cables/connectors:
40A 12V power supply (will need a little more if you want to use the full 500W on a 24V LFP):
(EDIT: ebay has lots of 12V server power supplies for cheap, see below)
EDIT: I had inadvertently linked XT90 connectors. Fixed.
A little more spendy than the 30V/10A power supply - about as much as another Overkill, BUT it has multiple benefits.
Fab balance leads
Fab main charge cables
Attach to PS and battery
Set Balance charge parameters and peak current (stay within limits of power supply)
Press start
Walk away
Unit will charge at the lesser of 20A or the limit of the 40A power supply, and you'll need to set the charge current @ 16A for 8S.
Once first cell(s) hit(s) limit, current is tapered to hold that voltage, and it begins balancing other cells.
Once cells are all at peak and current drops below threshold (usually 10% of start current), charger stops, battery balanced. Done. Drop your mic and take a bow.
For 8S and smaller batteries, you could leave the balance and charge leads attached. If you ever need to top balance again, such as after a period of storage, you'd simply plug in, turn on, press start and walk away. PROFIT!
Yes, more expensive and less flexible than a 30V/10A supply for other stuff... but be honest, if you had to buy one for this, you probably won't use it for anything else, BUT it offers maximum convenience and SPEED for initial and future top balancing.
Thoughts?

A little more spendy than the 30V/10A power supply - about as much as another Overkill, BUT it has multiple benefits.
- Up to 20A charging at battery voltage vs. 10A charging at 3.65V max when balancing.
- For 8S or less, you build the battery ONCE.
- Automatic balance charging
- Hands-free operation, set it and forget it even if you know you're going to check it obsessively.
- Future balance convenience for 8S or less batteries.
