New toy: #ISDT MASS2 USB charger. 6 USB-C ports and 2 USB-A ports. Up to 200W overall power draw. Each port has its own readings on the internal display or via Bluetooth LE and their app. And, using the app, you can schedule ports to be only powered during specific times. Oh, and it also has an alarm clock integrated. In case you put this thing on your night stand.

ISDT C4 EVO battery charger firmware downgrade

A while ago, I've bought the ISDT C4 EVO USB-C-powered battery charger to replace my MAHA C9000 (of which there seems to be a new "Pro" model available). The ISDT charger gets regular firmware updates which add new features and optimises the charging modes for different battery chemistries.

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...
