    Test/review of Charger LiitoKala LiitoKala Lii-500S

    As for C. If there are any batteries in the charger, you can unplug the power adapter cord and use the charger as a portable power bank, all Liitokala chargers have a usb for charging phones.

    Converting Thor Cyclops to HID

    It worked great, I kept the 12v sla battery, bought the cheapest set of lights and ballast kit on Ebay. I went with a 35 watt HID headlight bulb to have longer run time even with the large old style ballast it still fit into the cavity of the Thor. I picked up a second cyclops at a fleamarket...

    Converting Thor Cyclops to HID

    Sounds good, I already have several 4S packs & proper balance chargers. Back to HID fast start question, if I read your post correctly the ballast is what make the bulb quick start, the bulb has nothing special about it to be called quick start. Short arc would mean the ballast supplies DC...

    Converting Thor Cyclops to HID

    Thanks, now I know what to look for. I see alot of HID conversions for spotlights, is there a advantage to going HID vs LED? I see both in H4 style bulbs but have read alot of bad reviews on led's being over rated but never read anything bad about hid.

    Converting Thor Cyclops to HID

    What should I look for when buying a auto type HID kit for the conversion? I know the Thor uses H4 base so that's easy, also has 12v 7a sla. I have read alot about short arc, how can you find out if the HID is a short arc bulb? I will probably look on eXXy for a kit, but any suggestions would...

    SImple expanded scale meter circut for Lion cells anywhere

    Thanks for the info but I didn't want a 0-5v meter, got that, was wanting a 3 - 4.2v self powered. I have several DVMs but can't seem to remember to turn them off, 9 volt batteries aren't cheap. Need something I can leave laying around and know it's always going to work, self powered, good...

    SImple expanded scale meter circut for Lion cells anywhere

    I have tons of single cells from old laptops and alot of analog panel meters, I need a simple expanded scale meter circut to measure maybe 3-5v. All the DVMs on ebay only start measuring at 4v and up, to high for most old cells and I don't want a powered multimeter, just a devoted simple self...

    What kind of Lion cells are these

    Thanks, I knew if there was a answer it could be found on CPF. Yep I may remove the shrink wrap and see if the cooling band is removable, it would be interesting to have a high discharge INR cells for those high power led projects in the future. I did try charging some of cells up with Lion...

    What kind of Lion cells are these

    I bought some store return tool battery packs to yield some high current 18650 cells, one pack was a EGO 56v 2a pack, looked new. I took it apart and found 14 cells, all measured 3 volts exactly, I thought they may be INR tool type cells that run 3.2 v but that won't equal 56v, 14x 4 volts = 56...

    Convert flat top cells to button top

    I save old AA batteries, peel back lip around the top rim, the top hat can easily be removed with a putty knife and a tap on the handle. Then you can solder it the way that's bet for you, I use small solder wick braid, solder to the inside cup of the top hat then other to the flat top 18650...

    Anyone ever use a IR meter to check 18650s

    After shelling out a few hundred 18650s from laptop packs it was time to check capacity, I separated batteries down to a single cell and ran them through a charge/discharge cycle on computerized rc hobby charger. Problem is it takes 8-12 hrs to complete both cycles. I was thinking of buying a...
