Hi,

I want to run a SST-90 regulated at just under 9A.

Which battery combination would be better?? :thinking:

3 parallel AW IMR 26500 (2300mAh)

or

2 parallel Lighthound IMR 26650 (4000mAh) http://www.lighthound.com/Lighthound-IMR-26650-4000mAh-LiMN-rechargeable-lithium-battery_p_3478.html

or

3 parallel protected 25500 (3500mah) from DX http://www.dealextreme.com/details.dx/sku.26799

I wasnt sure if unprotected cells would be a good idea in a regulated supply situation??
