Convoy L6... XHP70 Beast!

Thank you Edness, glad to hear that. I knew they were flat tops,but price for the pair was fantastic !..…so… Solder blob no problem. :+1:

i wouldnt feel safe use the liitokalas as u have to use a blob or magnet to make connection in series, what if it shortcuts or something? since they are unprotected its better using the efest since u dont need any magnet or blob…

and is it even a difference if u get 15A or 17 will the lumens be much higher if any?

Solder blob is safe , magnet is not !

He did not say he was using a magnet. Those have risks if you don’t do it right. Solder blobs are super safe. Who told you they are a problem or unsafe?

Problem of using 2 x 26650 Unprotected in series is that the L6 low voltage protection can’t tell if only one of the cell is undervolted.
No good then for the average Jean-Pierre :wink:

But for the lightalcoolic that knows what he does and recharges the 26650s often , that should be ok …

I am still waiting for my L6 from GB and its 26650 Protected KPs from BG …. sooo long wait ….

Whether you use protected or unprotected, they have the same rules. Always use 2 identical cells, same age and same number of charges on it. Before you recharge them, make sure the voltages are the same. This way you know they are running down evenly.

If you just use 2 quality unprotected , but matched cells (bought together , not used seperately before) , they will still be completely fine .

If you want to be 1000% safe just use 2 protected (& matched) 26650 cells .

These are new batteries and solder blobs are safe! I’m sure some of us get a kick just to get one amp extra from an existing setup…at least I do. I just measured it with my light meter and those 2 amps definitely made a difference!

I use a magnet with a nylon washer around it to prevent it moving, is this the main concern when using magnets? that they will move and make contact somewhere they shouldn’t?

Yes, for instance if you drop the light on its side. The magnet might touch both the battery and the battery tube inner wall. If the inner wall is conductive, some are not, then you will get a short circuit.

The nylon washer around the magnet should prevent any issue, good idea.

Remember, the solder blob only has to allow contact, we’re usually talking about the thickness of the wrap so it doesn’t take much of a solder blob to get that contact. I like doing both cells and alternating how I load them when recharging, sometimes in series one cell will discharge slightly more than the other so alternating them helps keep them in balance.

And yes, 2A is major when you’ve gone to great lengths to get everything possible… if a cell change nets 2A then by all means use it!

I was gonna say, if the long protected cell wont’ fit take the protection circuit off. :smiley:

i look almost everyday on nkon for the Keeppower to get in stock, still nothing :frowning: is there really a shortage on those cells or? it feels hopeless to find good cells in EU bah…

so I have ordered an xhp70.2 Led for my L6 but I’ve just looked and it is available in 6v or 12v. which is the correct one to use?

thanks in advance

The appropriate one is the 6V.
Will you be running it on the stock driver?

Phew!

thanks Bilakos :wink:

It also needs to be 20mm.

The emitter is the same regardless, it’s the board that it’s mounted on where 6V or 12V get’s determined. :wink:

And yes, in stock form the original XHP-70 is on a 6V 20mm MCPCB. Mine are all now 26mm MaxTOCH.

I forgot, but will my L6 work with two NCR18650B protected cells? I am looking at these ones. They are 65.5mm flat tops. https://www.amazon.ca/gp/product/B010LTDFBK/ref=pe_1243740_268305490_em_1p_2_ti

Aliexpress sells them but more expensive and ships them to countries that others will not ship too. Many websites that sell keeppower will say out of stock if the country you select is on the list not to ship to such as Canada. Banggood won't ship to canada anymore and says out of stock, but if you choose usa, they are in stock and ready to ship.

They might work but you would need a spacer. The L6 is designed for 26650 batteries
