Two thoughts/observations: 1) when hedging, I usually would trust a product with 243 reviews (Obtronics), more than one with 10 reviews; it may apply/help here. Also, 86% 5-star reviews is quite high for that many reviews -not that the 10 reviews aren't also quite positive. 2) The Fenix batteries linked shows "currently unavailable" in or for my neighborhood. You may be patient or have better info; but, I also couldn't compare prices which would be my other factor. Enjoy the eventual 1800 light.
