Q:Can you use rechargable battery packs on an ordinary xbox wireless controller?
It has to be a battery pack specifically designed for that controller otherwise it won't fit.
Q:Will ups battery backup time how to count?
This is the theoretical calculation, the actual discharge, then there will be a lot of error, which is related to the battery discharge curve, 100AH battery with 100A discharge, put an hour, about 40 minutes to the battery cut-off voltage, and to protect the battery, UPS Will stop the discharge.
Q:what wires are required to turn 3 x 12v SLA batteries into a 36v battery pack that can be charged?
It's not a good idea. Batteries in series have to be perfectly matched or they'll go bad fast.
Q:Airsoft LiPo battery help?
You can build an adapter for practically anything. Whether the motor burns out depends on the battery you use, not the connector. They are two separate issues. If the motor is going to be burned out by the 11.1V 2200mAh 25C Li-Poly Battery Pack, then it will get burned out whether you use Deans or Tamiya connector. Having said that, the question is whether the Tamiya will be able to handle the current that the motor draws (without heating up and melting. That depends on a lot of factors, such as how much current the motor will draw, what kind of wires you are using, what kind of gears you are using, etc. Sometimes, that just requires trial and error.
Q:Black and Decker 18v trimmer lithium battery?
It depends on the model. I doubt you can build one.
Q:Ups the problem of external battery pack.
Your UPS inside the series of two 12V battery, do not remove the original battery in the case, you can put your battery in parallel and then connected in parallel.
Q:DSLR battery grips.?
You can use grips with only one battery.
Q:Medela Pump In Style battery pack question (for traveling)?
get an extra battery. trust me on this
Q:Xbox 360 Battery Pack Problem?
It's not uncommon for a wireless controller's batter pack to behave like that. There are several different things you can do. The first is is a more sarcastic approach in tightly taping the battery to the controller. The second is to be extra gentle in setting the controller down to determine the exact level of sensitivity so you can put your controller down without losing the wireless connection. The third is to hardline the controller to the Xbox, though that would obviously take the fun out of playing wirelessly. The fourth and least likely option is to buy a new controller. Generally, the most frequent cause of a controller's disconnecting is lack of contact between the battery and the controller. Even the slightest lacking will sever the connection to the Xbox. If the battery pack fits the compartment on the bottom of the controller perfectly, and you can't push it towards you and feel it budge, then it might not be the battery pack; it could be the controller itself. If that's the case, you are likely looking at a possible replacement controller. It happens. Sometimes you get a lemon. Make sure you don't buy merchendise at gaming outlets. As unusual as that might seem, you'll commonly get a better deal if you go to Target or Walmart. Before you consider the possibility, I would strongly recommend you try my trouble shooting suggestions mentioned above. Experience has shown the problem to be between the battery and the controller. It might be different for you. Good luck!
Q:L.E.D battery pack with different modes?
Battery packs don't have different modes. What you are looking for is some sort of control circuit. There are thousands to be found. Of those, maybe a few hundred would be something that you might be able to use. The hardest part will be choosing the best one for your purposes.
