Advantages:
(1). Lithium batteries are light in weight, small in size, large in capacitance, high in energy and high in safety
(2). Lithium battery core raw materials. The core itself has overcharge, over pressure, and over let the flow of four safety protection. It fundamentally solves the hidden dangers of short circuit, leakage, explosion and other aspects of lithium batteries.
(3). Lithium batteries use lithium battery cores in series.
(4). Charging chip protection plate(using military-grade smart IC chip, with over current, over pressure, overcharge, overcharge, under voltage, short circuit, reverse connection, equilibrium voltage and equilibrium charging and other multiple protection functions) to ensure the safety and reliability of the battery pack.
(5). Lithium batteries are used for a long time. The cycle can be charged and discharged more than 600 times. LED light source operating time of 20,000 hours, lithium battery life 2-3 years.
Why us?:
(1).More competitive price! As a manufacture,we have our own factory,so the price will be much more competitive!
(2).Great quality! All the cells we use are A grade cells,100% quality check and full one year warranty!
- Q:I need to build a battery pack that will last a min 2hrs to power a motor through a speed controller. The motor will be run at the slowest speed possible.Motor Specifications:? Torque: 12.0kg/cm? Rated Voltage: 12.0V? Operating: 4.5 - 18V max? Current - No load: 70mA? Current - Full load: 1380mA? Gear Ratio:
- You need to do two things to work this out as you have not provided enough detail. Step one: Determine average motor current over the two hour period. Step two: Calculate the required AH (amp hour) rating required for the batteries. Step one: connect an ammeter to the supply side of the speed controller. Run the motor at the speed you require. Measure the current. (lets assume 300mA) Step two: Battery Capacity. Lets say you need 3 hours run time. 300mA * 3 hours 900mAhours required. Check the AH rating of your batteries. (lets assume they are 450mAH rated) Building the battery pack: You neeed 8 batteries in series to get the required 12V. But if you did this you would only have a 450mAH rated battery pack. You need to double that, so put another 8 batteries in series. That will give you 900mAH which is what you require. (total 16 batteries) If you have 900mAH batteries you would only need 8. If you have 450mAH battaries you would need 16 (two parallel lots of 8) If you have 100mAH batteries you would need 72 batteries (9 parallel lots of 8)etc If you have 1800mAH batteries you will still need 8 to get the required voltage, but the motor will run aproximately twice as long as with the 900mAH solutions. Hope this helps!
- Q:Will ups battery backup time how to count?
- Battery capacity * Number of battery blocks * 12 * 0.8 / total power = backup time.
- Q:i have just receved a venom racing 3000mah 7.2v 6cell battery pack. does any one know the charging rate?
- this okorder
- Q:Black Box G1W plugged into a 20,000mah external battery pack. Fully charged battery, how long can the dash cam stay on until the battery runs out?
- hard issue. research on google. that will may help!
- Q:I just bought myself a nice, new laptop. Now I've heard two different philosophies when it comes to making the battery pack in it last:A) always plug it in and use it as rarely as possible in battery modeB) always run it in battery mode until totally empty, then recharge, and use again in battery mode.Somehow, neither of these feel completely right to me. Memory effect, limited number of charging cycles what's the generally accepted opinion in geek circles?

- Q:Hello. I am working on a project with a friend and will be wiring together many different colored led's together for a costume we are making.I am pretty good with soldering and thought this would be a fun project but we are looking for a battery pack we can buy that has different modes that you can switch too. So the lights flash or do other cool patterns.Is there something like this?Thanks!! :)
- I don't know of any battery pack which has different modes. I think what you need is a switching unit of some sort. If you search Google for led sequencer you will get links to circuits which you can put together yourself or ready made ones.
- Q:i have a battery battery pack (aka it takes batteries) and i dont like the rechargeable ones (because we own so many rechargeable battries) but now the battery pack doesnt go all the way in and every five seconds i get the please reconnect controller thing is there any way i can keep it in
- Use duct tape?
- Q:battery pack
- Google it or stop in at your local Home Depot.
- Q:Every time I tap on the battery pack on the back, it disconnects my controller. It's extremely frustrating because every time I put my controller down on a table, it disconnects. Does anyone know why this is? My battery pack doesn't look loose.
- 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:battery pack
- You could go back to the store where you bought the item and ask them for a replacement. Look very carefully at any embossed wording on the item, or a tag that is fixed to it, and try to find the company that made the item. If you can find an address for the company, send a letter to their customer help office to get the information that you need. If this battery is not removable, then the item will have to be disassembled to replace it. If it is easily removed, take it out and take it to a store that sells batteries to match it with a new one.
