Using Ridgid battery to power Shark Cordless Vacuum Vertex DuoClean, LZ462H

[@skyler5212]

The "power" you compared really isn't that relative to how well it is going to work. Electric motor speed is dependent on voltage. The vacuum motor is going to be approximately 25% slower at the start, and continue to get slower with an 18v battery. Slower motor = less suction. The current rating on the battery can never be "too powerful." The device connected to the battery will only draw what it needs. The amp hour rating is really just a measurement of how long the battery will last. It would be much better to use a 24-volt battery, but obviously what you have will work and it will likely last longer than the original battery. You're just sacrificing some of the suction. Good video, I'm going to do something similar.

The best thing about these Ridgid batteries is that they have the battery management for over discharge protection in the battery unlike the other major brands (dewalt, milwaukee, makita, etc. all have the BMS in the tool). The only other manufacturer that I'm aware of that also does this is Ryobi (also owned by TTI) but their form factor doesn't lend itself well to DIY projects.

I plan to wire three 18 volt Rigid batts in series to power an EGO power tool. Need to 3d print mounting and switch - working on that. Hope 54 volts is sufficient for the 56 volt tool.

If you reverse the polarity would you get a mini leaf blower?

Didn’t know you could do that nice to know thank you I have done a few videos on mine too but nothing crazy like this

[@chrisconnolly6524]

I think you have gotten lucky with your numbers. You have mixed up energy capacity of the battery (Wh) with power (W). The machine will draw whatever current it needs. Just because you are using a 4Ah battery does not mean the battery will supply 4 Amps. For instance, your 4Ah battery is rated for being able to supply 4 A for an hour before the battery is considered empty. It could supply 16Amps for all we care for, as long as it doesn’t overheat, but then it’s likely to only last 15 minutes. (Actually very likely the case in this setup). So what’s my point? Comparing the watt-hour capacity is pointless. In this case, what matters is the battery being of similar enough voltage (which you’ve got lucky) and being able to supply the current needed. And your tool battery is more than capable of that. And the reason I mention it is because people might think it’s fine to use a much larger voltage, but because the Ah rating may be lower - which is dangerous. I stumbled across this post because I’m planning on building my own battery pack - and it’ll be the full voltage, but I plan on something like a 12Ah capacity - so the thing lasts more than 15 minutes on full power. (So my Wh rating will be well and truly beyond the original - but that’s immaterial, because in this case I just need to match the battery voltage and make sure my battery will be able to handle the current draw, which it will). Please be careful with your instructions. If you are not 100% sure of the theory here, you really shouldn’t be trying to give a lesson on it for others to follow. Dangerous.

Amazing! I wonder if this will work with a cordless shark Stratos

[@jflats8361]

Grest video. Can you tell me what the run time is with this 4.0 battery? Thanks.

[@DIYDharma]

I don’t use it for ling periods so can’t tell. I use it to pick up things off the kitchen floor, dead bugs in the basement, etc. I don’t think it will last more than 30 minutes of continuous use.

[@thanunvsn7345]

can you please provide the name of the battery adapter ? thank you

[@DIYDharma]

I bought them off ebay but they don't have a name or logo on them. They were a two pack. I can't find the seller. Sorry.

[@the1spurs]

Can’t find those adapters any where

[@DIYDharma]

Here is one I found on ebay. www.ebay.com/itm/373711648582?_trkparms=amclksrc%3DITM%26aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D245022%26meid%3D0deb40b42f3345f2b68d739739d21402%26pid%3D101195%26rk%3D5%26rkt%3D12%26sd%3D125543796874%26itm%3D373711648582%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv11WebTrimmedV3MskuWithRevOptLambda85KnnRecallV1UpdatedPrice%26brand%3DUnbranded&_trksid=p2047675.c101195.m1851&amdata=cksum%3A3737116485820deb40b42f3345f2b68d739739d21402%7Cenc%3AAQAHAAABIATTvUhf9weceaKbX5LvBjvPjEhDzrCECR1YF2hmJp%252BY3cKnSDVzdwt2NHzOMyyyOoavCkbiJbFyLOYBO2W7CrFs8F3wGZ9lriP2YJm81zysV5mxiV55vcUciQihAaU9v%252BTQ1Vr9ESZdBieW14nbfWyRmPxguRprRXwR4piaaHYW3aSKzp9KWqH0Sn2H8B9LPOVKmYH6E18ss6bMVOnQJSV1yAy9a1JSnT2Vn3ni0mjwNeUQOZl7MTg6qQoiEAPA%252BdUszizWiRyA%252FrPS6N3XL2nmQl%252Brw12sarmH8Vhm2jbQNcIAOJnaVy7%252FkU0g68eqpqLd2tBvoZWIPZ399GaTxa2FIbRHWdRcvli5P7SA39%252BPtEk9f1dLFDwUSHSNh%252Fbe%252FQ%253D%253D%7Campid%3APL_CLK%7Cclp%3A2047675, but it is more than what I paid.

Will this work on shark vertex

[@DIYDharma]

Shark has many products named Vertex so not sure. but if the battery is the same than it should work.

[@douglaswildner619]

You didn't SHOW how to connect it to the Shark.

[@sunstyle52]

What about a Milwaukee 5 am battery? Lol

[@pesto12601]

of course you also added like 5 lbs to the lightweight cordless vacuum... just saying...

[@richardludvigh5575]

Seems like your math aint mathing you are confusing Watts (W) with Watt hours (Wh). Wh as no impact on the performance of the tool. If I put in a 700V battery that is 0.1Amp it will be 70Wh, pretty close aint it? But man you should see the sparks if u ever turn it on

[@DIYDharma]

Perhaps the math is off a bit but no issues in using this for over a year. Most recently, I ran it for more than 20 minutes non-stop. the one thing I will say is that if I leave the battery connected to the vacuum, it drains overnight. So I just don't have them mounted. But no sparks or heat.

😨 DON'T LISTEN TO THIS GUY BEFORE READING!!! 😢 I'm sorry to say, but you have no idea what you are talking about and certainly no place giving electrical advice. I don't claim to be an expert on this kind of thing but I know just enough to confidently say that you sir, have absolutely NO clue in the slightest. Please be careful with what info you dispence to people. This deliberately sounds harsh but I'm hoping you'll understand why after reading. I do apologise if it upsets you though, as that is definitely NOT my intention. I'll try to give a VERY BASIC explanation of a few things below so that you and others can get a brief idea of how this stuff works. Keep in mind this is BASIC ADVICE and I am not an expert by any means, but the below is generally accepted as common knowledge for this type of thing. First of all: Please understand that "Amp hours" (Ah) and "Watt hours" (Wh) only refers to CAPACITY and has NOTHING to do with output. Eg1: We have an appliance that requires 18Volts (V) and 1Amp (A) of current giving a total of 18Watts (W) of power to run... Using an 18V-4Ah battery will provide 18W of power for a total of 4 hours. Hence being called a "4 Amp hour" battery. Eg 2: If we have an appliance that requires the same 18V but a total of 72W of power which means that our 18V-4Ah battery will still output the same 18V However, it will now need to give 4A to achieve the required 72W of power to run the application. Because our battery is now using 4 times the current as it was in Eg1 (4 Amps VS 1 Amp) it means our 18V-4Ah battery can now only provide 1 hour of power at 18V to give the required 72W necessary run the appliance. Next: Depending on the battery chemistry and electronic management system inside the battery itself, these tool batteries will typically output much more than just 1A which is why the battery in this video would never run for 4 hours of continuous use in the vacuum because the vacuum needs much more than 18 Watts to run. Finally: The battery voltage and amperage is specified by manufacturers to achieve the desired power needed to run an application and depends on many things... One of which (amongst others) not to overlook is the size of conductors such as wiring and other components inside an application. As an example: In general, increasing Amps (in essence, the volume) of a set voltage means that the size of wire needed to carry the voltage also needs to either increase in diameter or reduce in length so that the resistance does not increase. Obviously wires can't always be shorter or thicker due to many factors, including, but not limited to things like keeping a package smaller, having enough space between parts or even reducing costs by using less copper. Instead, a manufacturer might increase the voltage and reduce the Amps to achieve the same power output. Relating to the video: In this application the battery will be using much more than 1A to run the vacuum. Reducing the voltage from approx 25V to approx 18V means the amperage will need to increase to provide the same power (scroll to bottom of this comment for the simple formula explaining this) and if the appliance and its components are not designed to handle this, you will have increased electrical resistance in the wiring/components causing excess heat which can lead to damage/failure or worst case, fire and injury. Conclusion: All being said... I've done this mod with my Dyson using Milwaukee batteries without issues, but I did my research (Note there is only approx 2V difference between my Milwaukee battery and my Dyson) Not saying what has been done in this video won't work, but if you do this mod, be aware of the potentials implications. Side note: If anyone cares to do further investigation, the first the basic formulas to understand for this application are: P=I×V I=P÷V V=P÷I Where: V - Voltage or "V" I - Current (Amps) or "A" P - Power (Watts) or "W" Resistance is an extra component I'm not going into but google "Ohms law" if you're interested. R - Resistance (Ohms) or "R" I hope this info is helpful.
