The new best headlight

[Gubbins]

Hope it looks better in real life..

yes it is that bad

Bypass the bms and see what it is like.

cant its built in to the top off the battery case on the pcb but as soon as i turn the light on the led goes red on the light.

and for a split second b4 it goes red the small batt meter shows 7.4v and then drops to 6.4v.

 

[soundwave]

any ideas fkn thing just went bang pmsl wires getting hot now

 

[Gubbins]

Go get a whiskey and look at it again tomorrow

Clearly not fit for this type of use even before things went bang. I was thinking in terms of connecting the light with twisted wires along the lines d8veh was talking about. But I guess the truth is you would probably need at least 1.5mm squared cable if not 2.5 to handle the current theoretically required by this light, it would take the same sort of current as your motor albeit at a lower voltage.

Does the seller offer a battery to run it? It seems to me pointless to make something that has no use.,

Could a lead be rigged up to run 2 of those battery cases in parallel (8 cells) and with a thicker output wire to provide enough current without another blowup?

That's funny

the batt pack i have is fine as used it for my other light loads of times with no problems bar the leds on the back going down not long after i turn it on.

the leds look fine so something must have gone in the driver at the back but cant check as glued the led pcb in place.

not as if i even bloody used it never got hot as was not using enough power anyway lol.

sent email to seller see what he says as not left feed back yet tho has 100 bad in last month.

I buy a few things from China and I find that they arrive quickley considering the distance, the sellers are polite if a bit left field language wise, and are happy to try to resolve issues. Lets not forget how much we pay for some of these items.. I think the light in question cost about £15 including shipping half way across the world and the only reason SW bought this light from there is because if this existed in the UK it would cost rather more...... The battery box is another issue tho as I had a few problems with mine so lets see what SW gets back from that seller, who purports to be UK based incidentally..

its all ways a risk as if it does go wrong not much chance of sending it back even if it did cost 100 quid as it just cost way to much to send it back, yet they can send a 99p item for free from there, we getting fkn done over big time lol.

always had a part refund or other item sent out so not a problem as the light i have is better than this one anyway

if the light did pull that many amps and worked that be one bright light but the cables from the batt was getting so hot so fast it would have started to melt over a few mins.

same will go for the leds on the pcb as 11 of them will get hot and fast why it was only using 2.3a when it worked

if i done it right then it was 7.45v

I already told you that you did it wrong.

He's had a bad night

its the driver in the light for the leds thats gone but had no problems with my other light.

all the leds look fine so might add some power direct to them from the front

 

[soundwave]

looks like its dead got power to the driver '@ 6a but gets so hot have to turn it off so the pack can pull the amps but nothing power wise from the leds so looks like the driver fried them also so cant see there cree t6 leds and fake.

i took it apart so you can see even if i gave the power all 11 leds whould take the driver is the same size as my light with 3 leds in it.
