Hello all..just got back from my 1st night ride with my new cree t6 1300..charged up the batteries and tested it out side 1st..all good and super bright..it took me 20od minutes to get to the forest on med beam..switched to high beam and with in 5 minutes it kept switching to med beam??..fitted the second batt and with in another 5 mins it done the same thing??..then about another 5 mins it switched to low!!..then they both died..so lucky i took a spare light..just tested the batteries and they have 3.2/3.3v in them..do i need to learn how to swear in chinese or is this normal for these lights..i thought the high beam with just get dimmer not switch down..thanks for any help..Z

I had a very similar thing happen to mine on its second time out. it just went from high setting to low and that was it, could select anything else

I ended up having to send it back

i also had issues with my t6,dimmer than it should have been on all settings .
rather than send it back to dealextreme i emailed smudge (a forum member) on sales@mtbbatteries.co.uk.
he sorted it for a small fee and its been working fine up to now.he'll tell you if it sounds sortable or not.

Hi yah.
With it being so new I would suggest you get back in touch with who you bought it from first. If its Dx then usually a proof of postage sent to them will be enough for them to send a new one out to you.

It sounds like a driver problem if you are having problems with both batteries and unfortunately I don't stock spare drivers for this brands of light.
It may even be over heating and the driverprotection is kicking in.

Sorry I can't help much but get in touch with who you bought it from and arrange a replacement.

But failing all of that with no joy with a replacement then send it to me and I can see if its fixable or not.

nice 1..thanks..Z

They're not actually 4000mah.

2500mah is "normal" for a decent 18650 cell. Anything significantly higher is probably just not true, especially if it's on ebay...

They're not actually 4000mah.

I'm only stating what its says on them, i'm not claiming anything.........

And TBH i dont care what they are as long as they last a bit longer, and the ones i've linked to last longer than the other batteries i've got that say 2700mAh on them so thats all that matters to me.
