    Battery pack for dental light?

    Hey all, I'm off to Guatemala to do some volunteer dentistry.
    I'm bringing my biking lights on GoPro headbands, but would also like to donate some lights similar to this.

    https://www.ebay.ca/itm/Clip-On-LED-...S7:rk:193:pf:0

    The light is decent, but the little battery pack with the driver and dimmer in the battery seems a bit dinky.
    I'd like to run the light off my 2S battery packs, but need a way to regulate them down. I need a lot of burn time, not a lot of lumens.

    Think I'm OK opening up the battery and putting some leads and a connector so my bike batteries can supply the power? Any better ideas?



    I'm leaving in just over a week, so not a lot of time to order stuff from overseas. Thanks in advance.

    Nah, of course not. I didn't get this model. There are some that are $25.

    The ones I'm looking at are around $150 and the key is that they cast a nice narrow circular beam. The battery packs are available for around $20, but I'm not keen on LiPo Chinese contraptions- I'd rather use my numerous powerful reliable batteries.

    Well, I took the battery apart. The ends come off and presumably the guts slide out, but thereís a bare LiPo in there that seems to be glued in hard. I can get it out but may puncture the battery.

    I was just hoping to jumper a connector on to the battery leads to use a real battery with the driver, but Iíll need to destroy this one to do it. I donít want to do that this close to the trip.

    How about a different tack- anybody know of a driver for a single LED with a potentiometer-type dial control that I could add inline to my existing 1S or 2S battery packs?

    I have made a couple lights using the Buckpuck 3023-D-E-1000P driver. Is has analog dimming input that can be used with a 5k Ohm pot.

    Thanks, that should do it, or Iíll get another cheapo battery pack to cannibalize for parts.
