The new best headlight

Ebay seller is sending me another battery pack. So if the next one is better I will have plenty of hours. Thanks for the info guys.

Even if it isnt at least you have two which will double your run time.

i charged up 4 cells in the batt box with a 8.4v wall wart that comes with most batts from china and this is what the cells were after a full charge

4.24v

4.24v

4.23v

4.22v

 

so all cells are over 4.2v so id only use that way to charge the cells only if you have to as if you keep charging them like this all the cells will go out of whack balance wise over time and damage the cells.

How accurate is your meter? How long since you last changed the battery in it?

2 weeks ago it over charges the cells and then drains them to about 3-3.1v

 

thus why i use a separate charger for all my cells;)

I'd blame the BMS in the box not the charger !

I was considering buying a bat box but not now you posted your findings.

I thought it would be easier than useing my RC balance charger ;)

it is but just need to keep an eye on the cells voltage but with the 6 pack i got i doubt the will ever get as low as the bms cuts them off.

 

it was only 10 quid but i have other ways to charge them anyway so just a way to get them on my bike.

Would I be ok with a 4 battery box? My bike battery goes flat after 15-20 miles so I only need about 2 hours of light. The light I just ordered apparently uses 5 amps but I don't know what setting that is on?
5 amps lol more like 500ma half of 1 amp. but yes 4 should run a bike light for hrs if you get decent cells.

had to glue some small rubber feet on it as still moved a bit but solid as a rock now.

 

and some 3m sticky label like plastic Velcro for the usb.

I'm a fan of frame bags, they keep my light battery close to where the light is mounted and I can put all that stuff in there that would have been in my pockets, phone, money, keys, emergency fruit pastels ;) (other sources of quick energy are available) and a small coffee stop lock.

I was asking about the accuracy of your uncalibrated £5 voltmeter. You'll be lucky if the reading is within 0.2v of the actual. As the battery goes down, they always start reading high - as much as 50% over when the battery is nearly flat.

 

In other words, just because you see 4.24v in the LCD, it doesn't mean that's what you have.

Good news for me. The ebay seller has sent another battery pack. I just tested it after a 4 hour charge. It did 2.5 hours on full. I ran down the other one ND M giving that 4 hours and will time that tomorrow on full. Should be a lot quicker lol

How many cells?

How many cells?

4 cells in a pack. And unless i made a mistake on the switch over, the poor performing one did 2 hours as well. Wheras before it was an hourmor less.

Doesnt really matter now doese it? You have a spare in your pocket so can go out in the dark with complete confidence..

So what is the best light on the end?

 

Nearly that time of year again. I need to get a decent rear light this year too

Best rear light has to be Cycliq Fly6 inc camera, filming is on a continuous loop.

I swear by this little guy...

The cradle stays on all the time and the light slides on/off when required. Charges in any USB without a cable and doubles as a brilliant (hoho) little torch too. I just bought a helmet variant too

The best one is a legally approved one (just in case you are involved in a crash) and from my experience at speed you need at least 70 lux. Lux are the number of lumens mer square meter on the road a more significant value than pure lumen output.

 

I like a couple on the front but unfortunately that is illegal, you can have several tail lights however. So my strategy is to have the front lights grouped together so that I can claim it is a single beam. If you have a 70 lux and a 40 lux headlight (as I do) the sum of the lights is 110 lux which is as much or more light than your average moped. I am comfortable at 60 km/h in the pitch black countryside.
