You are correct, I believe I bought my batteries separately from my head torch and they were not cheap If I recall. I do think even if you bought the head lamp and threw out the batteries for some separate ones, the rig itself is very much worth the price.
Why don"t you just stick a report up & show us all how good the potential "Headbanger"
is for underground stuff. i"m sure people would be interested in actually seeing the output/results from this, especially as most people on here seem to resent spending more than a Fiver on lighting at the best of times
The general concensus with Lithium iron batteries for Torches is to avoid anything with the word "Fire" in the name as there are thousands of posts online about these (mostly) ex Laptop batteries (or worse) going Pop at the very least
There"s a reason why button top protected cells are the price they are (unfortunately) My 4 Nitecore 3400mah cost me @£80 which were the highest output available at the time ......apart from
Fires which were available in 5000mah for @£20
Obviously i feel short changed by Nitecore
If you"re serious about going underground spend the money for decent gear and then spend it again on back-ups just in case. If you"re just Derping I"d still avoid
Fires
