Triple Shot Baterry "SHOT"

Posts: 586
My cateye triple shot charges in around 10 mins acording to the red light changing to amber on the tranny box the light also fades from super intensity to the sort of thing you would expect from standard cell lamp after around 15mins. I am assuming the battery is shot or on its way.
Looking at the battery pack it appears to be 10 AA rechargable Li-On cells wired in sequence so my question is has anyone ever made up a new set from new cells from RS and the like perhaps even use Nickel-metal-hydride batteries
Any thoughts. Oh by the way a new bat pack £80 odd There are a lot better lights on the market for perhaps £30-£40 more.

There are a lot betterl ights for just 30 -40 pound in all honesty if you go the torch route!
What voltage do you need? I take it 12v? There are a few battery packs around.0 -
You should be fine making up a battery out of high power NiMH bats as modern LEDs have power regulators which will regulate the power. Depending on the driver it might take an input voltage from 3 - 18v without any problem. Subject to the driver and testing - I'd over clock as you will increase the running time.
Check though that those cells are not 18650 or CR123 Li-ion cells. these are popular cells in China - see my laptop thread in General. I found 6 2.2ah 18650 in an old laptop battery.
Alternatively replace the lights with a couple of Cree R2 WC 250 Lumen torches.
See photos F4.0 1" exposure 200mm Canon IS on a 450d
I run 2 on the bars and 2 on the lid. 2 are enough to be honest. I tend to run them all on half power. to get more of a flood.

This is two of them running at max power.

Thanks for that mate, I thing the driver is mounted within the light unit itself so will be difficult to get at. Not sure by what you mean on Over clock (increase in bat capacity?
Anyway thinks i will give it a go Google is full of assistance and folks experience.

No, £30 to £40 in total, inc charger and batteries.tony.w wrote:supersonic wrote:There are a lot betterl ights for just 30 -40 pound in all honesty if you go the torch route!

Yes the driver will normally be soldered to the back of the LED mount. So you can plug your new pack directly in to the previous connecting points without modification.
What I meant by over clocking is that say, your current pack puts out 9.6v your new pack could go to 12 or 13v without much risk, because the driver will regulate the power.
The problem with going NiMH is going to be weight. for example... you can wire 6 x 3.7v 18650 2.5ah in two sets of 3 to give you a 5ah, 11.1v power pack which will be pretty light. The equiv in AA will be 20 cells at 2500mah. and may even cost more. Not to mention that you have 20 batteries to charge rather than 6.
A twin pack of 18650 2.5ah rechargeables £5.42 = £16.26
A twin pack of AA 2.5ah rechargeables £2.96 = £29.600 -
Thanksfor your advice I will get and look at it.0
