Serious flaw for NiMH charging

Do not use this to recharge NiMH packs or you'll risk destroying the batteries, the charger, your wiring harness and potentially starting a fire. BuddyRC refuses to comment on this via email, but the manufacturer wrote to me saying this device is not able to recharge NiMH.

The automatic cell count will treat a low voltage cell as multiple cells, and send 30 volts directly into two AA cells. This will melt wires, destroy your AA batteries and eventually burn up until the connection is removed. Unacceptable and BuddyRC doesn't care. Zero customer service regarding potentially serious safety issue.

Great, fan speed can be noisy

I wish there was more care taken on the NiMH part where a discharge->charge cycle can be included, but this charger can take on a ton of lipos without struggle (but at max fan speed which can be heard outside the room with the door closed)

ISDT K2 Air AC 200W Dual charger

Works great. I needed a charge to charge two 6 cell 5000mah batteries on AC when at the field and it does that and more. It is replacing my old worn out four port charger. Much more accurate.
