Which batteries for 41CV?

If so, it's about 4× higher than optimal. Has anyone had any "troubles" from charging the N cells this hard? The page directs you to use 200 mA and not the 500 or 700 mA settings, but even 200 seems pretty high to me for these little cells.

Nicad and lead acid mebbe , but NiMH can be fast charged without problems.. as long as it's an intelligent charger which takes charging current, cell voltage and temperature into account.
You can charge as fast as 1C with these safeguards
