    4xAA with rotary switch

    Due to a change of work (no night work anymore), I have been out of the game for a very long time. Now I need a 4xAA with a mechanical rotary switch for modes (and on-off too if possible) I have one like that - a Sunwayman M40A which I like very much but clearly is quite outdated now in terms of...

    Medical examination light

    Something like this costs AU$ 800 https://amamedicalproducts.com.au/collections/medical-lighting/products/welch-allyn-green-series-medical-light-gs-600-with-table-wall-mount Anything similar but non-medical so it will cost much less? It needs to be powered from 220-240v source, has adjustable...

    Back after a long time. Acebeam K70 or Thrunite TN42?

    But cells can be discharged down to 2.5v so from 3.7v to 2.5v we have no way to tell?

    Back after a long time. Acebeam K70 or Thrunite TN42?

    I have been using protected cells only. If I use unprotected cells in K70, how do I know when to shut down the light to prevent overdischarge?:thinking:

    Back after a long time. Acebeam K70 or Thrunite TN42?

    1300m vs 1550m may not be much different in real life I hope. Also I have a very soft spot for lights with ring control!

    Back after a long time. Acebeam K70 or Thrunite TN42?

    Doesn't K70 have overdischarge protection (light shuts down when cell drops < 2.5v)? If not then does it have battery indicator LED (eg if indicator LED is red then we know to change batteries)?

    Back after a long time. Acebeam K70 or Thrunite TN42?

    So K70 it is then. I ordered it at A$242.95 from liteshop (Aus). Now which batteries to get? Acebeam says "high drain unprotected 18650 cells, or protected 18650 cells which PCB including 3 MOSFETs" But some here on CPF had serious doubt about that and suggested normal 18650 cells should be...

    Back after a long time. Acebeam K70 or Thrunite TN42?

    Li-Ion batteries 2 years vs 10 years?

    I thought the batteries in cars are proven to last as the first Prius was made longer than 10 years ago and they did come with 10 years warranty on battery packs?

    Li-Ion batteries 2 years vs 10 years?

    Why all phone, tablet and laptop batteries certainly will have about 50% capacity after 2 years and many will be dead on year 3 Yet the batteries in Toyota Hybrid cars and Tesla new Powerwall are guaranteed for 10 years What's the difference between those Li-Ion?
