    Black and Decker's"VXP 7v Lithium-Ion battery system"

    I need to set up a 14v system. I'm building one of achesalot light set ups with 3 Seoul P4 LED's and I also need a battery for my old "night sun" 12v system I was going to run it at 14v as well.

    here the deal...I saw this at Home Depot a Black and Decker "VPX 7v Lithium-Ion battery system" the 7volt Lithium-Ion battery is about $20 and a charger with one battery was I think about $40
    here is a link to B&D http://www.vpxsystem.com/products/Pr...roductID=18380

    I was thinking of running them in series I think the the VPX system cells are 1100mAh
    anyone have any thoughts on this Black and Decker VPX battery thing?

    thanks Billy

    I saw a commercial last night for the B&D VXP system and had the same thought......"Will this work for a bike light??"

    everything I see I think..."Will this work for a bike light??"

    looks like some of the tools use two battery's and they are rated at 14.4V
    but from some of the reviews I've read the tools suck....but all I care about is the batteries and it looks like they are only 1100mAh

    I thought the same as you guys did, plus a friend emailed me telling me about these new power tool batteries that we could use for bike lights.

    If they are only 1100mAh, then I would say don't bother.

    But if you have a use for the tools as well, it is a good value.

    my thoughts as well...I did not know the mAH until after I did the post

    this looks like a better deal but batteryspace is out of stock.

    anyone have a source for 14 volt hi mAH batteries @ a good price?

    thanks

    what run times are you expecting you'll need for your lights. I think that is what it is going to come down to. I bought a 14.8v 4400 mah battery for 60 bucks and a charger for 20 at all-battery.com and that would give you around 4 times the run time and only about $20 more than what you are going to spend (alittle more for shipping). It will probably be smaller in size and lighter than 2 of your B&D batteries but not sure as I haven't seen yours in person. Plus the all-battery batteries come with PCB protection for shorts and charging.

    But if you are on a budget crunch and $20 is worth saving and you don't mind the shorter run times it might work out for you. It would be something different than we normally see. And sometimes that is a good thing. You could run one battery and use a boost controller to power the 3 led's and just carry a spare battery incase the ride is longer than one battery can handle. Just don't know what kind of run times you need.

    Here is the battery I am using for my 6 led setup and I get around 1.5 hours on high (1000mah) and about 5-6 hours on low (350-500mah), with the 14.8v 4400mah.

    Hope this helps in your battery search.

    They also have a 14.8v 2200mah for $30 bucks

    and a 14.8v 6600mah for $100

    Brent thanks for the info.

    We are hoping to do the "Kona 24 Hours in the
    Old Pueblo" as a team of two Tandems so I'm making us up some lights. I think we can get by with 4 hours run time. and an extra battery just in case. Our set up will be a Night Sun Team (very old) with a 20w flood and a 20w spot on the bars and 3 Seoul P4 LED's on my helmet not sure how bright I'll need to run them.

    wish us luck
    thanks

    dam that is a pretty good deal. I just bought a 7.2v lith-on for like $50 bucks. Mine is probably smaller and last longer but i don't know about being 10 times the price. Oh well, something to keep in mine on the next build, hehe.

    Power tool batteries

    Billy,


    For what it is worth I have switched my bike lights over to run off of Dewalt power tool batteries. I got really tired over the years of yet another charger/wall wart/lost parts/ etc. I have some Dewalt tools that run on 12 volts batteries. These work great. They are not Li Ion, but that is coming soon. The advantage to having this set of batteries, always charged and usable in multiple applications is really great. The only down side is I have to fabricate my own plug and the batteries are a bit odd in shape. The later I solved by adapting a water bottle cage for holding the battery.

    In the winter I ride about 3 evenings per week, so they are getting constant use.
