Advice on using NiMH Cells from the BRCA Electric Board

No problems have been reported with those packs on public forums, so I'd not be concerned. For peace of mind, charge at 1C (so 3.6 amps for the Nosram cells, 3.7amps for sanyo, etc.) and allow the time it will take to get a full charge. Use a good delta-peak charger, or, if you have it, a thermal cut-off set to 40degC, and placed in one end of the stick pack.

There is a known problem with IB cells, but previous issues with NiCad/NiMh going back 30 years have been due to users abusing their cells. I would not worry about your cells if I were you.
