I must say, this is one of the most well thought out builds I've seen for a long time. Careful wire runs etc. Suggestions, if I may, I would also have another 2 series links (like another comment said) and I would like to see some thermal separation between the charge controller and the battery pack. Either the thin composite board for even Kapton tape in a pinch. Also, I know it was sped up and it's hard to tell, but when using the heat gun to shrink the plastic, take a break every now and then so as not to stress the cells out from overheating. Oh and whack some hot glue or kapton tape over the 12v terminal undersides for good measure. If something pops off under that lot, then there could be a colourful fireworks display. All just suggestions and not meant as a criticism.

I made one of these about 2 years ago using a commercial case kit inc BMS. No on/off switch but added a small push button switch and a battery level meter. I also made another including a cell monitor instead which shows voltage overall plus volts on each bank & alarms when individual banks drop below minimum volts. The level display and the alarm/monitor are available online for a low price and are a worthwhile addition.

I want to ask you something . Please tell me if you know about it. For many days I'm trying to find or build a hot cutter knife like tool which can cut the plastic so I can put switches , led lights or connectors in the plastic body. soldering iron only works for round holes and it gets messed up with melted plastic, small cutting disk doesn't work everywhere. I tried to modifying a soldering iron but it didn't work as expected. Currently I heat up a knife on the gas stove and cut the plastic with it , But it is so frustrating, I have to keep re heating it and I can do it in kitchen only, I end up giving up on many projects. Please tell me if you have solution to this issue. I'll be very thankful.

@Once_in_a_Lifetime 8 месяцев назад

I think he meant 50,000ma continuous discharge! I don’t know how he even can use this without a 5 v step down converter for the Usb ports as this is not a 12 v battery and should not be used as such.. I would have reservations about even using a pop bottle for this as I would want more insulated material used.

@sincerelyyours7538 Год назад

A very fine build, I was not aware that a pack of 18650 cells would fit so perfectly inside a 12V gel-cell case. Also was not aware that a PET bottle would shrink so nicely over an 18650 pack - a good idea if/when you don't have commercial Heat Shrink Tubing that large when you need it. I would like to give three minor suggestions: First, go easy on the heat around the cells when shrinking down the covering (as Lloyd's Shednanigans suggested below) to avoid overheating the pack. Second, use 1/4" tinned braid instead of flattened solid core wire to join the cells together. It's just as thin but will carry more current and give you a small degree of flexibility which could prevent a cracked solder joint from disabling or causing sparks inside the pack. And third, put in an inline fuse, such as an auto fuse, above the cells like you did the switch and USB connectors to protect the pack from over-current situations.

Good skills. Good ideas. Perhaps the cells should not be touching each other to allow air gap for air flow to cool the cells. The shrink wrapping with PET bottle also restricts a lot of air flow. Not sure if the final product is a fire hazard or not.

@barthchris1 Год назад

Fire hazard? No. If the cells are heating up to the point that combustion was possible you are abusing them not using them. Heat produced during normal use would not create any issue whatsoever.

Nice. But I prefer 4S LiFePo4 for lead-acid alternative because of better voltage equality and compatibility with chargers and equipment and higher currents capability. Did in same case battery from 4 32700 6a-h elements, it can start Yamaha R6 engine. Now building in case of originall motorcycle battery which is a 5mm thicker so I can install 4x 33140 15a-h LiFePo4 elements, and battery is still lighter than original lead-acid was (2kg vs 2.8kg)

@ncdave4life Год назад

I completely agree, Sobakin76. Lead-acid batteries charge at 14v. With only three 3.6v lithium-ion cells in series, you get 14v / 3 = 4.67v charging voltage, which is way too high. The BMS will presumably lower that to something reasonable, but probably at the cost of a lot of waste heat while charging, and you'll get less than 11v out of the resulting battery pack. With four 3.2v LiFePo4 cells, instead, you get 12.6v, which is a perfect match for a lead-acid battery, and you get the longevity and safety of LiFePo4, too. Where do you get your 32700 or 33140 LiFePo4 cells, are you pleased with their quality, and what BMS do you use?

@Sobakin76 Год назад

20:20 The bench PSU was shut off because the over charge protection (battery BMS) turned off the charge, the battery voltage was over 12.9V which is too much for a 3S Lithium Ion battery pack. Li-Ion cells should not be charged to anything higher than 4.2V per cell, which is 12.6V total. So you need to set your power supply to 12.6V and wait until it drops down to a very low charging current.

@ErCanEverything Год назад

You are absolutely right. I wanted to show you that the BMS automatically shuts off once it reaches a critical voltage for the batteries. I set the power supply above 13V to show you that the BMS works, but the current must be observed according to the numbers of batteries and the manufacturer's specifications.🙂

This battery is not available to a car or motorcycle. Because in those voltage is on 14.2volt level. Simply acid battery can be loaded by 16.2 voltage. Maybe we can take one liion battery more on one cell than a capacity. Then in the loading process we have 12.6 plus 4.2 and will be 16.8. And in the lowest lvl of voltage will be 3.3 x 4 equals 13.2volt. A little more than we need. 14.2 is the limit of loading in cars/motorcycle. And this is a little under we want. In the past I think about this kind of battery and this kind of problem. But if we want a good capacity of power bank we have a good one sample on the move. Good job.

@@budzio135 Car or motorcycle batteries will usually be much larger than 7Ah. Car batteries in particular will be about 80Ah or more, so this small battery will not be able to replace a car battery. However, for 12V appliances that need a lot of power and need to be portable, this battery pack is ideal. So boomboxes, portable televisions, etc. I will probably make one myself for a 12V car clock, which has always been known to chew batteries.

@@ErCanEverything It can't work properly. 12V application will try to charge battery to 13.8-14.4 volts. BMS will cut off overcharge, UPS will loose battery. If you wanna use it as USB power bank, that's another question :)

It's much more useful if you go for LiFePO4 4s rather the Lipo 3s... The 3s won't match alternators and other 12v systems properly.

@kiryutinaleksey Год назад

Exactly. 4.3x3= only 12.9V. But usual chargers give 14+V. So it will be 4.7v per cell. It is well too much. May explode.

One suggestion: The USB modules have LED's on them, You could have drilled holes in the lid of the box above the LED's then refilled the holes with clear Epoxy, this will allow the lights to be seen as an indicator the the USB modules are turned on. I've done this many times and it works well.

@bentheguru4986 Год назад

Good time chewing video watch but here are some points. The pack is 3S and not 4S thus voltage output and charge voltages lower. Lead-Acid (LA) runs very different volatages and current flows on output and charge. Putting Lithium into a case designed and configured to plug in LA applications just doesn't work without changes to the system feeding to/from it. So many have gone down path of trying to run UPS's of these turds and find it sucks bad, especially with 3S. If you wanna build a power bank, put it in a different container/package.

@ErCanEverything Год назад

Initially I also thought that the voltage would be low, but they are almost identical. the minimum voltage for LA batteries is around 10 ~ 10,5V, for 3S it is 9.6~9.9V, I even made a 3S 22Ah Li-ion UPS pack and so far I have no problems. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cf-4e0qoOVM.html

@isaacmayorga3932 Год назад

Hello, as I have been able to observe, it was enough with a charging voltage of 12.65 maximum 12.7, when applying 13v that's why the battery shows a voltage lower than 12.6 since the bms protected it.... On the other hand what a good battery elaboration!!!

@@ErCanEverything Yeah, after i saw what it was gonna be used for i disregarded the need for extra copper..

@isaacmalco452 2 года назад

Wires on bms needs to be on same lengths and gauge sizes to have similar resistance for accurate voltage balancing.

@isaacmalco452 2 года назад

And you can atleast put a voltage indicator to let you know the charge level..

@ErCanEverything 2 года назад

There was no space for a voltmeter but I will add an external small voltmeter

@Micro-Motive 2 года назад

Not quite correct in regards to voltage balancing, as the voltage balancing only occurs during the charging cycle at lowered current. Hence the resistance of the wires in the BMS Monitoring path (Resistivity * cross-sectional area * length) is not a significant factor during the charge cycle Where the wire size does matter is in the discharge path - the cell to cell connections, the Cell Bank +ve & - ve to BMS B+ & B - , and the BMS P+ & P - to the External Case Terminals.

These has been my challenge with these lithium ion batteries. Full charge is 12.6v. Without using dedicated lithium ion battery charger, you will not get the full charge. Other charges will cut off at 12v or a little above that. So, how do you solve this challenge?

@bentheguru4986 Год назад

No, think about it some more. Dangerous idea building Lithium into Lead-Acid cases.

@ErCanEverything Год назад

It was an LA battery from a UPS whose charging voltage is 13.7V. I made a 3S 8P Li-ion battery that can be charged at a maximum of 12A, I don't believe the UPS charger will exceed 4A which will not affect this pack. And once the voltage reaches 12.7~ 12.8V, the BMS will automatically stop charging

@bentheguru4986 Год назад

@@ErCanEverything and totally different voltage profile to what the UPS is expecting thus you won't get anywhere near a deep discharge or most of the actuall current Lithium can produce. Unless you have a lithium configured UPS, stick with a chemistry it is designed for. Besides, 3S is a cheap way out from using 4S.

@Micro-Motive 2 года назад

Sorry, but your execution of this idea has so many flaws that it's seriously dangerous if used for any other purpose than as a USB Powerbank. 1. WHY DESTROY A 12V 7Ah SLA JUST TO GET A PLASTIC CASE? Sell it for recycling and use the cash to buy a NEW EMPTY CASE (Complete with Nickel straps, Cell holders and the same 3S7P-40A BMS) off AliExpress. 2. Good soldering requires mechanical as well as electrical connection. Relying on just the solder joint is downright dangerous - the slightest imperfection in soldering or overcurrent will cause the joint to fail through high resistance. 3. I like the idea of hammering heavy copper wire into strip form, but it doesn't have sufficient cross-sectional area to carry the possible maximum current draw from the battery Cell String. Make your connections from the Cell String to the BMS from the centre of the String rather than the end. That might prevent the solder joints from melting or the copper strip becoming a fuse. A 55W Headlight globe drawing just over 4 Amps is hardly a good test of a 40A+ capability. 4. While the wire Guage used is fine for recharging or running the USB Converter, it is way too thin to carry the 40 Amps continuous (70A+ startup) that at the BMS is capable of supplying. 5. The BMS is primarily designed for a 3x7 18650 LIPO Cell configuration, but will work fine with 3x8 Cells or any 3xX Cell configuration with the corresponding capacity, current and charging limitations. Don't mix cells with differing current, capacity or Voltages. 6. Using the plastic bottle as shrink-wrap is an old but conceptually good idea. However in this case it's way too thick and acts as insulation to concentrate the heat from the cells leaving the heat nowhere to go - you're risking the cells overheating which could be disastrous! 7. Using "recovered" or "second-hand" cells adds further to the risks, just to cut costs. 8. The commercial Lithium Battery replacements for the 7Ah 12V SLA use Lithium Iron Phosphate (LiFePO4) Cell chemistry NOT Lithium Ion Polymer (LIPO) I'll leave it there - CAVEAT EMPTOR - if you buy into this without knowing what you're doing then you are taking a serious risk.
