would you need to swap the plug or can you get adaptor to fit

[risingfriend 1,042]

just buy an adaptor mate you can pick em up for a £1 from your local poundland etc. ATB Aaron

Just a word of warning , i dont know about the NS ( weather it uses rechargable`s or not as standard ) BUT a rechagable will run at a bit more than a normal . For instance i have a surefire torch , that runs on CR123`s which are 3v . The rechargables of the same run at 3.7v and have blown the circuit on it . I returned it ( lifetime warranty ) but was STRONGLY advised against using rechargables . Just a thought , check with NS if i were you .

I use the one risingfriend mentiond and it should plug stright into the NS no adapters needed.

Same here we use the blue one which works a treat. No adapters needed.

[remyd 68]

lol but how do you charge the battery? think they come with a chinese plug!

[zini 1,939]

It comes with a UK plug to charge it if you ask when you buy it on EBay.

[risingfriend 1,042]

sorry mate mine came with a chinese plug and i use a adaptor plug but as Si said you can ask for a uk version. ATB Aaron

cheers again lads

some notes on rechargeable lithiums.

 

ultrafire are 1 amp no matter what they say on the sticker, most are refurbished with new caps on. the protection curcuit does work on individual cells, but..erghhh i've tried 6, they wont run right in series to make a 12v pack..(11.1v becacause the cells are '3.7'volt' as in 3x3.7v in series) i even had tiney sparks inbetween the batteries..fffff avoid!

 

with the lithiums, theres two types, protected and unprotected.

the protected shouldnt go bang under dubious condisions but have a lower realease, as in cant get as many amps out for hi power or slightly less for time use.

 

i think ZINI mensioned battery packs a while ago (i think? lol) who ever it was they had a valid point on the capacity, a 9800mah pack takes ages to charge on a 350mah charge current, the maths sais 9800/350mah = 28 hours.. mine have been on for 3 days before now and no full charge indicated.(the black box version)

so the 6800mah packs may be better for that reason.

 

a note on capacities, very few are as stated most are under the stated rating. the worse they are are or cheeper they are the less is in them. (right down to 4amper ultrafires coming in at 1000-1200mah as in 1 amp not 4...without the protection curcuit on a charge rate for 4 amp, thas a big arsed boom!!).

 

nar then.. the voltages on CR123's and those types are 3v 3.2v 3.6v 3.7v... match them to your stated disposable voltage, and yes the disposables are rated similarly in volts, theyre not all same.

 

if you run a lithium too low its dead, the odd one can be badgered back into life but usualy theyre fubar'ed (f*cked beyond all recognision lol) same for nimh batteries ish.

 

if your making packs up read up on them a lot first theres a few suprises you really dont want. a decent charger is a must, one that balences.

 

if you need a pack a night or more look into the RC hobby stuffs, the ones with hi charge rates.(or buy more of the battery packs already mensioned..to cycle so ones on charge as you use the other or more).

 

 

edit in...get a voltmeter..as standard to see what you got. a full lithium is about 4 volts to 4.2 cut off on a charge, it discharges to 2.4v is puhing the limits very closely..but, they voltage sag a bit when in use..some worse than others, so say a 2v drop in the voltage in use if you measure the current, switch off it goes back up to the battery's idle state voltage).
