2 week old Cree T6, fully charged, failed on my way to work.

Send it back, you have just been unlucky I think

@fossyant Is it better to let the good batteries run down to red before recharging them, or keep topping them up?

Keep topping it up. If you run it to empty you'll kill it.

The battery packs and often the chargers are shite. I complained and the seller has despatched a free replacement. The batteries from Chinese sellers tend to be recycled laptop batteries so are always a lottery. Treat the head unit as a cheap quality light, and get a replacement battery from Torchy, Mtbbatteries, build your own using a battery box and quality protected 18650s (not ultrafire, trustfire or setyerbleedinghouseonfire) and enjoy hours of brightly lit cycling for less than the price of a 10 speed cassette.

If you haven't got a separate charger where you take the batteries out to charge, swap two of the cells diagonally in the battery casing, as they charge in pairs using the magicshine chargers.

As cubist says, keep em topped up

Cheers both, I take them out of the pack and use the charger you recommended. keeping them topped up makes it easier as I can leave it at home rather than carry it to and from work every day

I had to adjust my T6 light the other day(it was pointing towards the pavement) now its spot on in the centre of the road, but I broke one of the O rings that hold it on, so had to use the spare one that came in the box.
can I get spare O rings for the light. if so does any one know which size and where from?

Never used this dealer so can`t recommend them.

The Xtar charger takes a while but it is a smart charger and controls how the batteries charge. If you trip the protection circuit by running them too low, the Xtar charger won't charge a tripped cell. I thought I'd knackered mine, but what you do is leave the batteries in the pack and connect up a magicshine/T6 charger and it resets the protection chip due to the voltage. The Xtar being a smart charger thinks there is something wrong with the battery if it's tripped. The magicshine chargers are very basic.

Thanks for the link, now I know the size (40mm and 50mm) I had a quick look on ebay and found some

[QUOTE 2827294, member: 259"]Just another late word of thanks, Fossy, it's a great box. Cheers for getting it all together![/quote]
Been using mine for the first time proper this week, so far it's had 3 x 45 minute commutes on full and 1 40 minute commute on low, will run it tomorrow to see how long it'll last but am more tham happy to get any extra time now

I put in the batteries recommended by @fossyant and got over six hours of full before the red light came on.

Yes I saw your post about the ones you'd put in, mine are a little lower powered so will be interesting to see what the difference is

 

[fossyant]

My new lights have been posted !! Hopefully they will arrive before my commuting on bike starts again on 6th January !

Update- 4 x 45 minute commutes on full and around an hour on low, still going

Plan is to run them to empty, this should be OK @fossyant with my T6 charger?

 

[fossyant]

You can run till low as they are protected. Worth doing the once to find out run times. Don't do it regular though as they prefer to be topped up. 3 hours on full is great
