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.
i look almost everyday on nkon for the Keeppower to get in stock, still nothing is there really a shortage on those cells or? it feels hopeless to find good cells in EU bah…
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.
You can use 18650s as long as you have the spacer, but the NCR18650B is not a great choice for this light because of the cell’s high internal resistance. They will work, but the light output will drop more quickly than with higher performance cells.
Gnope. If you’re gonna use 2, you’ll need button-tops. You “can” use small Nd magnets to bridge them, but drop the light and they theoretically can shift and short the positive to the (negative) tube.
Plus, they’re great for up to 3A or so, which is fine for smaller lights, but will limit current to the L6.
