Yes you can add that if you want, but as I manage my own batteries and have an intelligent charger and know how I soldered and potted them in my case (really impossible to see a short circuit happening) I do not find that necessary... For sure in my camper van when I installed 510Ah of 3...

ps I also ordered to boost the original light output: 1) A cree Petzl replacement bulb £9.99 - https://www.ebay.co.uk/itm/283428800153 (120 lumens) 2) Some super bright 5mm LED's (these are 20mA so 7 will run about 70 hours!) - they are the brightest ones I could find that gave a reasonable spec...

Here is the initial approach doc, and questions just let me know: First there are some important points: 1) Li-Ion cells are potentially explosive if heated too much (and this increases if you incorrectly fully charged them), so you do need some decent kit to do the soldering quickly. I include...

I'll write something up in the next few days Ian!

Hi Frog2, if you have the old Speleo Technics cases if they are no good to you I'd happily buy them!

ps Oh just a thought, if anyone has lying around some old Speleo Technics battery cases they don't want I would happily buy 1-2 of them now I have my approach nailed as they are really a better case than the Petzl zoom case! ;-))

Dear Frog2, thanks so much for your reply, sorry for the silence I have been away on a family event. Things have taken a more extreme turn, I bought a balanced 'charge anything' charger from Amazon, that proved the NiCad's were totalled (and yes they were NiCad's Fjell so you were right, so my...

Just for interest Fjell, my mate has the same light as my wife's, he's just charged it up for the first time in ages (think years!) and apparently it's been going with the light glowing brightly for 8.5 hours so far and no sign of stopping yet ;-) - so great!

They are NiMh as they are the MkII but I still need to test them... I bought a hobby multi-charger for all types of battery so when that arrives tomorrow I can try them out.... I also bought a 4.5v LED Petzl head torch replacement for the halogen, so we'll sort that out first. I then assume I...

Hi All, I'm after buying a speleo technics mains charger if possible for a Headlite lamp. If not, as I can't even test the output of the charger nor a reliable battery voltage yet can anyone tell me what the charger is outputting (voltage and if poss amps whilst on charge) and the voltage of the...
