Battery Pack?

Hello everyone,  I want to build a battery pack so that I can charge it with solar.  i bought some 12v 1.3ah sealed lead acid batteries but they don't do the job that I want to and they are not very appealing.  So I have seen the tesla powerwall and it is great and also slim, so what I want to do is to buy different batteries which are the panasonic 18650 and the stack them together to my own specifications so that they can power small things such as lights and pumps.  The packs that I will make would be small at first just to test and have an idea. So is it worth investing in these battery types or just buy some sealed lead batteries and then stack them together.  Thanks

Battery pack rebuild

I read the instructable on rebuilding the 14.4v cordless tool battery pack and I've done it before with a decent Milwaukee battery. Now I have one that the thermistor is shot. It said 6k8j on it. It was a disc like an advil pill with two leads. Where would I find a replacement? I've looked on digikey.com but can't make heads or tails of it. I imagine you would want it to stop charging at 70 degrees c like a lot of r/c packs do.

Building Battery Packs?

Hello all! I am currently in the process of designing an (increasingly) large project using LED light strips. These are the strips I intend on using. Expensive? Yes. Worth it? It should be. The other thing is that this is a portable project, one that I want to be able to use without being tethered to an outlet. Basically, what it comes down to is that the project involves using about 8.25 meters of light strip. I say about because I haven't done precise measurements, but I'm buying ten meters which should be plenty. This adds up to 264 LEDs total (for the 8.25, not the 10). Each LED can draw up to 60 mA at full brightness, so all of them at full brightness would draw almost 16 A >_< I am thinking that the best way to go about this would be to build four smaller battery packs, each powering about 2 meters of strip. I was looking at using these Li-Ion cells. The only problem is that I do not know how to accomplish what I am trying to do. I am still befuddled by the relationship between a battery's "C" rating and its mAh, and I am quite unsure of what kind of circuit these batteries need to be used with to prevent killing them, or worse, fires. What I really want is to be able to run the entire thing for 3-4 hours on a single charge of all four of the battery packs. But I also want to have the possibility to run all the LEDs at full brightness (albeit for a fraction of a second) without damaging the circuitry. Another problem I am encountering is that these batteries are 3.7V, and the strip needs about (but no more than) 5V to run. I appreciate any advice, help, references, etc. you can give me. I don't need a full blueprint or schematic of how exactly to do this, but I do not even know in which direction to start looking. Thanks again.

Building a USB Battery pack for Nintendo 3DS

Hi everyone, I'm not a total stranger to this site, just my 1st time signing up and posting. I'm asking for some advice for building a USB Battery pack, I've already got my prototype for a simple pack using 3x AA Dry cell Batteries, i know some things about electronics already, but i need a little more advice about Undervolting and Overvolting. Using the Dry cells I have 3 batteries which will give me 4.5v, my intention is to use 4 AA NiMH cells, and those are 1.2v which will give me 4.8v, and the 3DS has a 4.6v requirement for a charger, i have a few other questions too. i'm worried these might damage the 3DS in the long term, would the 0.1v undervolt or 0.2v overvolt actually damage my device with the DC Current, or would it just draw what it needs? Would i be better to add in a voltage protection circuit, and while i'm at it, are there any circuit diagrams for building in a Charger for the NiMH Batteries in the unit? Thanks for any help in advance, and will appreciate the feedback

practical uses for plastic six pack holder rings? seem like they are very durable and useful.

Thought these might make good tool organizers, mesh bags, or any potential items that would be practical, useful, and eco-friendly. Discarding these without clipping the rings has had a negative impact on wildlife by entangling them, so thought would try to put them to good use and save money. There are likely many gardening, art and craft applications for these also.

Convert A/C to Battery Pack?

Ok here is what i wanna do, and your all gonna think I am crazy, but this is mostly for my little girl.  I want to take a very cheap dvd player and another cheap video screen, (the kind you find for the back of auto head rests) and glue them together, make a battery pack, and wire the two together to the pack and, the point is I have the devices and they both are rather low energy draw devices, so i just need to know if I can make a battery pack or perhapse a radioshack project battery holder and how many batts I would need etc.. I will admit the math is a bit confusing for me. but here it is, the dvd player is rated as AC 120 v, and it says it has a draw of 10w, which if I am not mistaken is very low drain and awesome for an ac device.  the monitor is DC with an adapter but can also have an optional car adapter (which I don't have, but I would just use the transformer's cord/jack to wire it in.)  The back of the monitor says it's DC output is 1.2A and again 12v and the transformer itself says it's input is 24w.  So if my math is right, I am looking to make a battery supply to support a total of 34 watts and then I will use both cords to wire them parallel to a battery pack that I need to make, so where I need the help is what kind of a batt pack do I need to make or is it even possible?

deep cycle battery pack

Does anybody know what parts I'd need to make a 12v rechargeable battery pack for an upcoming road trip? I also need to know where I can find deep cycle sealed lead acid batteries for this project. I waited long enough to make a lithium ion pack, but now I changed my mind on the battery type to get 12v, and now I have no idea of what protections and electronic components I need for it. I'l post more info on available casing later, but I'll tell you now that it's like a small blue lego briefcase from when I was little. It's about the size of a texbook and I'd like to be able to put it in a small backpack to carry around school sometimes for my windows tablet. Update: I am available to buy any particular case, but wiring in a case can sometimes look bad, so I'd like it to store all wires internally and have a friendly look. Appearance was part of why I switched my plan from li-ion 18650s to lead acid. A block with printed volt and amp information looks better than a group of oddly sized cells. Also, no clocks.

18650 battery pack question

Hello everybody, I need to install (build) a recharging battery pack for my plant shelf.  it will be running an arduino nano, just 3 leds (3mm 20ma each) 1xNTC and 1x water sensor probes (nails).--  no LDR no yellow LED. . I was thinking about getting a 2x 18650 battery holder - I need more battery hours, should we wire the batteries in parallel to get more mAh and boost them 3.7V to 5V. so basically this is what I am trying to custom build to get more hours; DIY Mobile Power Bank Case Kit . I would just buy the mentioned product BUT under specifications>battery it says the capacity range: 1000mAh and below. but the batteries I have are 3.7V @ 5000mAh. does this mean that the remaining 4000 will be lost because the system can't handle it?  . basically what I am asking for is how can I make a long lasting arduino nano powering 18650 battery pack BUT also with a recharging module. these are the items I found that may work together, please remember that I have no electrical experience from before. I have learned everything that I know from instructables, this is a too advanced build for me to figure out without asking a few questions. thank you for your patience, let me know if I have to clear anything out. batt holder:  recharger: boost: am I even in the right track with this thing? can these be connected together and a switch. again, the goal is max battery life.. maybe add 4x 18650 - 2in parallel + 2in series, 7.4V to arduino Vin, eliminate the booster, even more battery life ? . thank you in advance, love & peace akin,

Monster battery pack for pedalboard

Hi! first of all happy being here in such a full and interesting community. Since some time i have an idea fix, i would like to play guitar in the street, not for the sake of money but for pure entertainment. Following that intention i´m being gathering all equipment i need for that purpose. I was asking myself the question about power source for all that stuff. Actually i can make it easy, since i already bought roland cube street, that runs on 6 AA batteries. BUT, i guess nobody here likes easy things. Therefore here is my project: using acoustic guitar with 4 effects and the amp running on the SAME external battery pack. short description of the project : 4s4p battery pack for a total of 14,8V and 12 000 Mah more or less.. will depend on cells themselves. Theoretically it will mean 10 hours or continuous run with all of equipment. of course there will be step down converter and other bells and whistles that i will be happy to share once i start doing it. Questions mainly are : I know that Boss pedals have center negative connection, What the hell does it mean? please someone help with this cause im getting mad. Is it just inverting the leeds? positive one going to the sleeve and negative/ground to the pin? OR it means that the pin has to be  minus 9V? This is the main question as i dont want to burn 200 euros pedals second and less important one: i will mostly go with NCR18650GA units. And will arrange a balanced pack. As the charging rate is 1A rough it takes 3,5 hours to charge. If the total capacity is 12 amp as i'm planning will it be neccessary to wait 12 hours to charge it or 4s4p scheme will still need 3,5 hours to charge all of cells at the charge rate of 1A, can i also charge it at faster rate as cells state that discharge rate is10A and so i coud use up to 10A charger? Or maybe the smart chargers identify by themselves the best charge rate? thank you in advance please know it's my first project of the kind :D

Retrofitting a battery pack into an ebike.

Ok I was just looking at this ible. And noticed the type of battery the guy used.  So I did some googling and ended up here. Wondering to myself about trying to retrofit this type of battery into a veloteq challenger from 2008 or so. Remembering that its a 48 volt pack built from 4x 12volt lead acid 20amp batteries(cells) wired in series thus to stack the voltage and not the amperage.   Now I know amperage is simply a measurement of consumption so I'm guessing that these Yellowtops are way above the usual 20amp's that the veloteq asks for but I'd imagine that shouldn't make much of a difference.  Seeing as I only want to throw on two of these as to not blow way past  the weight restriction on the ebike itself by hitting 48 volts with four of these also to avoid breaking the bank with an 800$ purchase.  Could I not add some sort of transformer to step up the voltage to 48 volts or something like this? Any suggestions are welcome but I can't imagine this would really be all that bad of an idea.  I'd imagine it should boost the range somewhat if not a fair bit.  I'd imagine that my assumptions here are not far off but I'm here to either be validated or corrected. Or even educated if someone has any suggestions or advice.

I just need to know what parts I need, and how to wire it all up. I know I need a switch that can be physically connected in way that a trigger pull will engage the motors. I know I need help. Please any help would be appreciated. I also would like to use "solenoids" or "Actuators" I just need to know from more experienced builders what would be better for an external universal type "pack".
