    I need 23mm glass replacement for UltraFire WF-606A

    You are right, from financial point of you, there is no point of restoring it. I am doing it purely for fun factor of "modding". I learned a ton about LED flashlights while doing it, I am replacing a bad driver as well as LED, I will be putting XM-L LED and relatively low current driver for...

    18650 PCB Query!!

    No, you would need voltage regulator to perform step down, that's not how this protection works, it supposed to "break" connection. I don't know what cell you are using, Panasonic for example lists 4.325 ±0.025V for their 3100mah cells. 4.25V would be ideal, but I doubt someone is using that...

    Really cheap true cc/cv usb charging board

    I saw your thread originally back when you posted, but it just hit me now after about reading old thread about using a cell phone a charger to charge battery, why not use a universal cell phone charger such as ebay item: 110816989744 ? It's dirt cheap and it has already AC plug (build in PS)...

    Can I use cell phone batteries to build battery pack?

    I have several cell phone batteries (same) and they are Li-Ion 3.7v 1300+ Mah. I've read somewhere that you're not supposed to charge it with hobby charger and it's bad idea to connect them in serries. I tried charging at 1A and battery remained cool, I had to stop the charge prematurely, but...

    Problem with new Pila IBC charger and/or AW Li-Ion 18650s

    Re: Pila charger behaving strange Wow, that's very informative, it give me much more insight in to Pila's history. I found a imax B6 for $20.99, but I don't know if it's real or fake, as HobbyKing is selling both, don't want to end up with low quality fake one....

    Problem with new Pila IBC charger and/or AW Li-Ion 18650s

    Well, I am certain it's better then UltraFire or other cheap chargers, I didn't trust TrustFire :) so I bought Pila, because I didn't see same quality alternative, but few days ago I emailed a company to find a distributor for Keep something batteries JHK reviewed recently and they responded...

    Problem with new Pila IBC charger and/or AW Li-Ion 18650s

    Pila charger behaving strange I just purchased my Pila charger recently and immediately I noticed a strange behavior, when the battery is near end of charging if I touch it to check on the temperature, the light turns green and charge is terminated. If I take it out and put it back, the light...

    Is it safe?

    Since my initial research on Li-ion chargers, I've spend more time researching and realized I was too hasty to purchase Pila, what I really want/need is hobby charger. Since 99.9% of hobby charger reviews always talk about charging Lipo battery packs, is it same charging characteristic as...

    2012 Battery test/review summary

    Thanks for awesome charts! It would have been real great if you could have sorted all your charts from highest to lowest performing battery, that way I can see immediately which battery is right for me.

    Is it safe?

    I did research before I bought Pila (I just bought it) and was certain that this is one of the best chargers for Li-Ion batteries. Someone mentioned on this forum that Li-Ion chargers are electronically simple in comparison to Ni-Mh chargers and yet, you can pick up a La Crosse BC-700 on Amazon...

    Is it safe?

    Today while charging my UltraFire LC 16340 880mAh 3.6v battery on my Pila charger I've noticed it was running very warm, that got me worried (this is new battery getting charged maybe 2-3rd time), since it was not too hot I decided to monitor closely checking temp with my hand periodicly and let...
