Make an inexpensive Lithium-Ion Battery Pack
can you advise a board for 4s4p on aliexpress ? for example https://tr.aliexpress.com/item/4A-5A-PCB-BMS-Prote...32581245955.html?spm=2114.010184.108.40.206z5kr6&ws_ab_test=searchweb0_0,searchweb201602_3_10056_10065_10055_10068_10054_10069_10059_10073_10017_10070_10060_10061_10052_10062_10053_10050_10051,searchweb201603_3&btsid=2f1f8179-8987-4db3-8b58-7928095e4f89

i just look for laptop batt then narrow down to but it now, then organize lowest price. here is a new 6 cell 5200mah for dell e6500 for 13.00.this should help find deals. - DavidC199

I have bought new laptop batteries that are inexpensive because of being a high demand battery. Tgen i take them apart to get the 18650 batteries. Benifits are i get 6 or more same batteries with solder tabs and it costs about 10 to 12 bucks delevered. And they are good ones also. Just thought i would share.
It IS Great.I think i can use the method to make a lithium polymer battery pack. like this http://www.unitbattery.com/product/12V-rechargeable-lithium-polymer-battery-pack-6800mah-for-cctv-camera.html
Hello! I'd like to follow your amazing instructable! I have a question tho.. the balance port is the only port required for charging?I remember using a LiPo Balance Charger before, i used to connect the Balance port and the +/- of the Output
i plan on making 3 of them for my rv
nice pack i am planing a 12v 500ah pack
I'd like to know if it's possible to connect two 6s4p battery packs which i bought from http://www.dnkpower.com/battery-solution/lithium-ion-battery-pack/ in series to double the voltage? can anyone help me
Hey I'm new to this hopefully you can help... Want to make a 18v battery pack for powertool i want to work with 2p5s configuration with 18650 cells ... Now live seen couple things that might help but I'm not shut soooo. Here's a list of the things18650 cell of course, a pcb with balancinghttp://pages.ebay.com/link/?nav=item.view&id=181949529109&alt=webA power supply http://pages.ebay.com/link/?nav=item.view&id=271666854840&alt=web Or a adjustable power supply http://pages.ebay.com/link/?nav=item.view&id=321829513465&alt=web. Would this even work i mean I've never done this before but indeed to do this for my personal tools but my problem is in in Puerto Rico and I don't have a place to go to and ask my questions so I decided to ask you guy's. A lot of questions but for now with these items mentioned will they work for what I want? Or if possible link me what would help. Please thanks for all your time..... Let me know....
Thanks for the instructable. Just curious where you state: "You can draw 10 watts from one for 1 hour or 2 watts for two hours." Should that not be 2 watts for 5 hours or am I doing the math wrong?
http://www.evlithium.com/lithium-battery-balancer....balancing current from the separate battery balancer would reach 6A at max.much better performance on balancing battery cells
its better to use separate battery balancer rather than a balance charger or charger with balancing function.
14 amp hour / 140 watt hour lithium ion battery
i have a device which runs on 36 V and draws an input current of 2.5 A. how can i use these laptop batteries to work with my device. ? i need a battery backup with 36V, 2.5A which lasts for an hour. thanks for the awesome article
Nope, 13s. It's a pretty standard replacement size for Sealed Lead Acid (SLA) x4. SLA are called commonly called 12 volt batteries when actuality they are 13.2 volts fully charged. When placed in series by 4 (48v applications) the actual charged value is 52.8 Volts. This configuration is used in wheelchairs, lawn mowers, golf carts, ebikes, etc. A Li Ion max charge is 4.2 Volt each. 12x4.2=50.4, not high enough for the max voltage. I choose to run a 13s @ 4.2v each for 54.6 V.As for your groupings, why would you do it that way? Is it not modular enough at 4p8s or 8p4s? I would think the 8s4p would be a pretty good way to go with a 2A charger and a BCM. This would charge them at 500ma each.BCM:http://www.batterysupports.com/lifepo4-nbsp-24v-nb...Charger:http://www.ebay.com/itm/8S-28-8V-29-6V-Li-ion-Li-P...You could create a "battery bank", and have it be removable. But don't run a charged battery and a discharged battery together in any circuit ever, unless you isolate them from one another. Bad things could happen.
I have a 13s I am working on bulding currently.http://www.batterysupports.com/44v-48v-504v-12s-30...
