So using 8s and up, your choices for charger/balancers goes down. I'm trying to find a simple charging solution. There are some very cheap, simple chargers out there, but what features are essential?
For instance, I was thinking I could double up on this small 4s, even leave it onboard if it's small enough:

Dimensions: 2.7 x 4.4 x 1.6 inches
Weight: 6.2 oz.
Output: 20w
The LiFePo I have now just has a simple LEDed BMS board I plug a high-ish watt AC/DC adapter.
