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!

- Q:What are the characteristics of the series and parallel battery packs?
- After the battery series, the voltage is added, the current is equal, thus increasing the voltage.
- Q:I took apart a dead Roomba Battery pack to see if I could replace a few cells and found that one of the battery's polarity had switched from negative to positive. I've never seen this. Luckily it was at a very low charge. Do you know how to reverse polarity on a NiMH battery so I can reuse it? Or am I out of luck?
- you can't. it's junk
- Q:I bought a 4 pack of AA batteries at the grocery store the other day and thought I forgot them in the cart because I couldn't find them. Well today I found them in my freezer. Must have accidently thrown them in while putting away the groceries. Can I still use them?
- It will do no harm to try to use them. Bring them up to room temperature slowly - just put them in the kitchen for a couple of days. Dry them off frequently when condensation forms on them. Then simply try them.
- Q:i found a couple of package deals, some with the battery pack and some without. do you need the battery pack for the wii to work or can it work with it? also if it is an addition what does it do?
- The Wii fit board uses batteries. The battery pack is for the board, you can play without it by using disposable batteries but if you play it everyday as you should you'll burn up a lot of money on batteries. I would get the battery pack. I have one and there is no telling how much money it has saved me.
- Q:I would like to run this motor intermittently using a portable drill-type rechargeable battery pack, maybe lithium-ion. How long could I expect it to function with say a 30 percent on/70 percent off duty cycle before it drains the battery?
- all of us else advised you regarding the motor, and that they are quite often good different than that maybe they are exaggerating slightly approximately what's going to ensue (e.g., circulate up in smoke, soften). yet be conscious! The wires you employ can circulate up in smoke or soften in the event that they are not heavy adequate (do no longer question me how i understand!). on the different hand, i think of they are deceptive you approximately your image voltaic panel. there isn't any such factor as a 12V panel. in the experience that your panel is labelled 12V, that in simple terms approximately easily skill that it replaced into designed for charging a 12V battery. I even have a 5W 12V panel that i offered to test with. In complete sunlight, this is open circuit voltage is 25V. when I hook it as much as a battery, regardless of the incontrovertible fact that, its output voltage is on the instant compelled to despite the voltage of the battery replaced into on the time. If the battery voltage replaced into low, and that i circulate away it interior the sunlight all day, that voltage will (ever so slowly) upward push. in case you do no longer use a charge controller, then it quite is quite useful to observe it, and disconnect the battery from the panel whilst the voltage gets up over 14V. a solid rule of thumb for lead-acid batteries, B.T.W.: in case you pick for them to final, then do no longer charge or discharge the battery in something under 10 hours. it quite is to assert, in the experience that your battery is labelled 12Ah, then you quite quite oughten't to entice from now on than a million.2A from it, or charge it at extra desirable than a million.2A.
- Q:I have an 1st gen i-pod shuffle and I've been looking on OKorder for a new battery (which requires soldering) but they also sell battery packs. Will a battery pack rejuvenate a dead battery or is it just used for extending the life of a good battery?
- challenging thing. check out using yahoo. that can assist!
- Q:I have an Olympus Camera with a Model LI-42B Battery Pack.I haven't used my camera in a while so I charged the battery then pulled it out of the charger and put it on my desk. I don't remember how long it has been sitting thereI got it to try and use it and the sides are puffing out!It won't fit in the camera any more!I'm afriad that it will burst If it does, what does that mean?Is it dangerous?I put it in a plastic baggie just in case but I'm worried and PISSED that the GOOD battery that came with my camera has crapped out so soon.What does this mean?
- That is not good at all. It seems like the battery is defective, or damaged. You should return it to the company for a replacement battery. Check you manual or the company website for service directions on returning the battery.
- Q:i hvae att and i want to put my sim cardinto my dad's iPhone. but neither of us know how to open upto the battery sim card area. does anyone know how?i've asked like all my friends and everyone haha help!
- Use a paper clip on that small hole on the top of the iPhone. The SIM card drawer will slide open from there. You can't access the battery at all.
- Q:I have a few cheap LED flashlights that I would like to power with a 7.6 volt R/C car battery pack. I used to power a regular bike light with it, but the bulb was for 7.5 volts. I'd like to go LED for better battery life. All the LED lights use 3 1.5 aaa batteries. Do I need to add anything (resitors, capacitors, etc.), or are they already in there? Any help would be great.
- That is a complex problem. First you need to know what specific bulb you are dealing with . Most white LED's typically run between 3.7 to 4.2 Vdc , and require 20-30 mA each to run at their full output. You say that the 3 AAA batteries are what they ran on originally, so that means that they could have only been setup as a parallel circuit, if they were in series that would require at least 36 volts. But you do not know the specifics, so here is how you start: Assume that the max voltage of the bulbs is 4.0 Vdc x 9 bulbs @ 20 mA each , powered by 7.6 vdc One 22 ohm 1 watt resistor @ 30mA each you would need one 15 ohm 1 watt resistor , but be careful you could shorten the life , or not, trial and error is the only way to know. Radio shack does sell a 22 ohm 1/2 watt resistor, and it would get hot, so you need to go to a specialty electronics(radio shack is not anymore) shop and find exactly what you need for around a buck. Oh and you cant take two 22 ohm 1/2 watt resistors and run them in series, that would result in 11ohms at 1 watt, and a bulb life of around 40ms.
- Q:I bought a pack of 4 Duracell rechargeable batteries with the charger for my camera and I plugged it in yesterday this time to charge all 4.It is almost 24 hours past and the red light is still on.My camera doesn't show me if the battery is charged all the way or not, it just indicates when its about to die so I don't know if the batteries are fully charged properly.Anyone know why I still get a red light and the batteries that came with it are 1700mAh and the are AA type off batteries.regards
- it could have grimy battery contacts. hit upon a chew of positive sand paper and sparkling all the battery contacts. If this won't get the charger to eliminate darkness from, there may well be an inner undesirable connection that may not be person serviceable. Me, i might take it aside and verify out the little circuit board for undesirable or broken connections and areas that may not be making suitable connection. using a soldering iron and good rosin middle solder will look after those subject concerns. a foul connection may well be placed by way of searching for loose areas and wires. If a ingredient is loose, you will notice a small ring around the conductor of reported ingredient on the solder pad. The section (or twine) could be good, and there could be adequate solder to make an outstanding electric powered connection for existence. in case you do not desire to bypass this a techniques, sorry, yet you may evaluate changing reported unit. i'm hoping i exchange into of a few help here. I desire you and yours properly. happy vacations.
