  1. I've recently discovered the ISDT CM1620 charging modules.

    They're pretty cheap (~140€) and promise some pretty good specs:
    - ~11-70V / 1100W input
    - ~8-70V 20A / 1000W output
    - LiHv, LiPo, LiFe 2-16S balance charging
    - Control via Micro-USB, Bluetooth, RS485, CAN or an optional controller with display

    From our tests, they work fine, even at max load (16S 15A).

    However, they do have some quirks...
