I did an analysis of the CBA II (warning...heavy reading) and had a mod to lower the operating temperature: viewtopic.php?f=14&t=8009
, The CBA III can operate up to 100W or so without overheating but if you're in a high ambient temp environment, additional cooling is advisable.

- Don't use a hub, peripheral or laptop USB port to power the CBA. Use a desktop's port so you get a 500mA port and not a limited 100mA port (which the CBA often doesn't like).
- Avoid discharging over 30A or so to prevent components getting so hot that they unsolder themselves from the circuit board.
- Using the CBA (any model) with higher voltage packs, above 12V or so, risks the random destruction of the MOSFETs even if the discharge is well below the rated max power of the CBA. This is a limitation of the MOSFETs they use and can't be worked around without replacing the FETs.
They're fantastic units though, even with their limitations.
