Interesting exercise. Certainly cool as a maker project. However, aside from the questionable handling of the electrolyte, the end results seems not worth the effort. First of all a regular alkaline AA battery is probably good for 1500 mAh, and a NiMH rechargeable AA is easily 2500 mAh and up. The 180 mAh lithium ion battery is really measly in comparison. I also wonder if there is any heat issue when you have to squeeze the voltage from 3V+ to 1.5V. My criticism/doubt aside, I applaud your efforts.

[@greggeshelman]

He put a pair of the 180 mAh batteries in so its 360 mAh.

[@butsukete1806]

The pack I got came with a 4 micro USB connector adapter, so best of both.

[@PunakiviAddikti]

This is a cool project, but there are some practical issues. The capacity of the lithium battery is low, so you're not going to get as much energy out of the battery as you would from a regular battery. The LM317 is a linear voltage regulator. It converts the excess energy into heat and has a terrible efficiency. A buck converter is better suited for this type of task, but it puts out dirty DC. Shrinking the charging circuit is *dangerous* if you aren't careful. One mistake and it could malfunction and put the lithium battery into a dangerous state. Lithium batteries are no joke, if they become angry they turn thermonuclear. Consider a slimmer charging circuit and a USB breakout connector instead. I know how hard it is to make electronics fit into a tiny space.

The most likely injury to happen when disassembling an alkaline battery is that you slip and cut yourself. Unless you're working in an oven or surrounded by exposed circuitry. at most you have the potential of some skin irritation due to the chemistry and I would imagine that's only going to happen from prolonged exposure or if you have sensitive skin. It's mostly safe. Just an absolutely inane modification.

All is great, but in that way there is no low voltage protection. Congrats for the work.

[@joemann7971]

I can't remember what the cut off voltage is for that voltage regulator but it will basically shut off before the lithium batteries gets completely drained. Low voltage protection would really only be needed if it was connected directly to the lithium battery but its not, and the regulator will stop outputting any power before it drains the better too much.

really cool fine work, but totally pointless energy wise, an Nimh battery will provide between 2-3Wh of energy is will provide 240mWh of energy and about 300+ mWh of waste heat. But even so if a thing takes 2 AA batteries it usually will run off one li-ion without reduction of voltage. because 2 AA can provide 3.4V when completly fresh as long as you have a circuit to cut off discharge at like 3V to 2.5V it will be fine (depends on cell).

[@sebastienmonette6659]

Well, chemical one use batteries deliver much more power per density than lithium batteries

[@RexxSchneider]

@@sugarpuffextrem Not really. You have to compare usable energies. For a decent alkaline battery that's probably more like 1.5V x 2.5Ah = 3.75Wh. For the Li-ion with a linear regulator reducing its voltage to 1.5V, you only have a usable voltage of 1.5V, not 3.7V. So its _usable_ energy is going to be 1.5V x 0.18Ah = 0.27Wh, which is just 7% of the usable capacity of the alkaline.

If you're trying to say that using a switching regulator could increase the usable capacity of the battery, that's not in dispute. But what switching regulator are you going to cram inside an AA battery? And how are you going to cope with the horribly noisy output that will screw up a lot of the equipment that expects clean DC from a battery?

Not as drastically as you think. The LiPo uses a much higher voltage (~3.5-4.2V) which means it can provide ~2W (4V * 0.5A). In comparison a typical NiMh Battery with 2500mA, 1.5V capacity can provide ~3.75W. It's still just half, but less worse than you would expect. Please note, those are very rough calculations and do not include voltage drop during use nor losses during voltage conversion of the lipo down to 1.5V.

А зачем оставлять в схеме подстроечный резистор? Логичнее было после настройки замерить номинал подсторечного резистора и заменить его постоянным резистором.

Com todo esse trabalhão eu teria comprado a pilha recarregável logo🤣 sem contar que saiu mais caro gastando com o Arduino, fonte, e bateria kkkkk

Kkkk vdd

Que arduino, doido?!

A questão do vídeo, acredito eu, que seja mais educacional e experimental. Vai dizer que não é muito foda o cara soldando os bagulho ridículos de tão pequenos e ainda fazer dar certo? Kkkkkkk

[@jonathanapestegui5383]

@@hallssoft7967 com certeza kkkk mas eu já desistiria só em abrir kkkkk mas soldar smd é complicado mesmo 🤣

Amazing Idea 💡🤩😃👊

Hola que tal excelente video pero cuál es el diagrama para conectar los componentes del regulador de voltaje? Saludos

Hello The datasheet file was inserted into the description.

I feel like the overall cost of this project Would cost more than a standard 2 pack of rechargable batteries Making your own is very dangerous

[@devansharora2453]

This is really an out of the box creation

Seems dangerous

No, not dangerous

bro a 1.5V battery is not scary at all i connected copper wires to it (it didn't get hot in the slightest bit)

[@Alternate-H123_22]

i'll tell u what u should be afraid of: any battery that is stronger than 3.7 volts no matter what (tho u do gotta worry about the wattage cuz my 9v battery is ATLEAST 10x stronger than my 3.7v battery in watts) so watch about for batteries stronger than 1.5 especially the 9v batteries

This video is about how to make a 1.5 battery from a 3.7 battery ? Great idea! Now it would be even better to make a battery for a wristwatch from a car battery - it would be cool in general...
