Test/review of UltraFire 18350 1100mAh (Black-red)

I was just suggesting that if they didn’t add the protection circuit they could sale the battery cheaper and we could buy them cheaper.
A few years ago when I was build a battery pack for a hunting light, I needed a protection circuit in the pack. As the current capabilities of the circuit went up so did the price, may not be that way now. But the circuit is adding to the cost of the battery.

Ok I see then. For the Chinese manufactures I suppose adding the extra FET’s is probably in the cents not dollars range.

I’m happy these have the protection, and to have 18350’s that can deliver the same current as unprotected versions. Also as I said above, aside from these UltraFires, I’m not aware of any other High capacity/High discharge protected 18350’s.

And there’s a deal on these today… don’t think we could ask for any cheaper than this: ☢ [Bilakos10 Premium Deals] ● Astrolux FT03 SST-40 ● Astrolux A01 UV ● Seeknite X6S ● JCD 8898 Hot Air Station ● SQ-D60
