If these batteries do not have BMS integrated, you could deplete them critically low and basicly destroying them. For an incidental cases it might work, but not for permanent setup.
@@theresatrickforthat I disagree. Luckily you are not draining the makita battery below its safety limit because the bluetti stops at 12.0 volts. the makita has a "bms" but only when connected to a makita device.
Dewalt does not have a cutoff in the batteries so I would be sure to include a disclaimer if folks use another brand of battery. I use Ryobi for this purpose since they are cheap, reliable, and have a low-voltage cutoff within the battery.
Thanks for the vid! I've been looking for something like that! As you may know there is a fully fledged war going on here in Ukraine, and those pesky ruzzians are tending to hit our power grid constantly. Those mean people want us all to die from freezing. So I was searching for a cheap solution for my eb3a capacity extension. Luckily, I have some 4A Makita clone batteries, so it'll be possible to make it last a bit longer on a frosty winter night, allowing me to keep my gas boiler up and running. Glory to Ukraine and thanks to all the free world for your support!
I have multiple power stations, pawn shops, and I put them together using a dc5521 to XT60 cable. I just use two Ecoflow River power stations, a 412w and a 288w, daisy changed while recharging from solar.
thank you for such an informative video about the bluetti, I had no idea that it was capable of doing that. You're a great teacher and thank you for the link because I'm going to buy that adaptor myself
So the concern is long term stress to these tool batteries. So it looks like the tool batteries will fully deplete in 30m at 18v/5a when charging the power station.. How hot does the battery gets when continuously running for 30min and if X degree for 30 min long is good for the batteries and the other components over a period of a year at 2x per week charging.
That’s a great question I don’t have an answer to. What I can say is my batteries are still going strong. However, I use them to expand my capacity seldomly just on camping trips or during power outages. Thanks for watching!
Hi, 1: Can we use a second large capacity battery (12V 280AH LiFePO4 Lithium Battery) with the same connection? 2: can we use a 20Amp 12V/20A Smart Battery Charger Lithium Lifepo4 charger for faster charging than the 90w charger? Thank you in advance for your response.
I think he is asking if he can use 12x20 (240w) battery, drawing the max capacity of 240w. I would say no as your video indicates 150W limit and pending the chemistry the 12v battery may not be able to push out 20ah I think the max output capacity for the tool batteries can push well over 150wh. The limiter is the power station.
Not sure I fully understand your question…but if you’re asking about protecting the small power tool battery from over dis-charging…that’s something each person has to figure out based on their batteries. I obviously use Makita batteries and they have a BMS in each battery unit that shuts the battery down to provide over discharging. Thanks for watching!
That's a good idea. How has it worked out in the long run? I'm still learning about all the different types of batteries. I've heard that using two batteries of different chemistry in this application can ruin the LiFePO4 battery. Thanks for the video.
Thanks for watching! It’s been working out great for me! No issues at all! The good news is that since I’m expanding the capacity through the DC input, I’m actually not hooking different battery chemistries up together directly. Rather the power tool batteries are sending power to the DC charger which in turn passes it on to the main battery inside the unit. So in this scenario, you can use any kind of battery chemistry you want and it won’t hurt anything.
Nice, I will have to try this. Max DC charge the EB3A will take is 200w in the manual, though 28v at 8.5a is a bit more (238w). Your 18v battery at 8.5a would top out at 153w. As the EB3A will pass through the input power then I expect it will take the edge of usage but drain your power-tool battery first.
@@JoeAnshien I would not do that it could do bad things :) What you can do is get a step down voltage convertor, which will drop the voltage to 28v or less (depending what you get). There will be some power loss but it should work. I have used step up convertors to turn 12v to 24v to charge things but personally not used a step down.
That is cool. I was expecting 100w charge rate. The standard charge rate is 260ish watts and obviously is only fully accomplished by AC charging and the turbo on my EB3A is 430w. But that's cool you can slow it down by using silent mode, I hadn't thought of that. Thank you!
That could certainly work in an emergency…I personally like the more solid connect these adapters provide and the fuse protection. Thanks for watching!
I am wondering if you are exceeding a safe discharge rate for the 5Ah x 18V (90Wh) battery, and are risking a fire. Maybe the Silent Mode is safer, pulling just over 1C from the Tool Battery.
Maybe so! I know the power tools themselves pull more than 1C all the time and the Makita batteries have a BMS that add an extra layer of protection. But I’m certainly a believer in being better safe than sorry. Thanks for watching!
Nice Video! Can you confirm the adapter cable you have linked is the actual cable you are using in the video? I've that particular cable does not charge the center pin and might not work with the EB3A. But, if you are actually using that same cable, I'm going to go ahead and get one. Thanks!
Thanks for watching! Yes, the links to the battery adapter and the barrel adapter for the Bluetti in the video description are the exact parts you see me use in the video!
I'm completely ignorant when it comes to electric. Is there a cheap set up like this with no wiring diy skills for the bluetti ac 180? It looked like you had to wire the barrel plug?
The EB3A is much smaller than the Delta 1300...so one 18V 5ah Makita battery adds about 30% additional charge to the EB3A if you don't have any kind of load on it.
If they run out completely be sure to charge them ASAP. The BMS will usually protect the cells with a low voltage cutoff, but if they aren't charged soon enough, they will completely die and there's no coming back from that. Thanks for watching!
Run a wire from positive to positive and negative to negative from another battery with the same voltage as the one that's dead. It will put enough of a charge in the dead one so the charger will recognize it. Good luck!👍
This is awesome, just awesome. I will do the same for my Ecoflow with my 40v Ryobi batteries BTW, the way to get above the 150 watt range is that you will need something that can pump close to 28v Thank yoiu

Unfortunately, as far as I know, you’ll probably at least have to do a little splicing to get the correct adapters you need. Thanks for watching!
If the Bluetti was at 50% then how much more can you raise the percentage to after fully discharging the Makita 5ah 18 volt battery?
The EB3A is much smaller than the Delta 1300...so one 18V 5ah Makita battery adds about 30% additional charge to the EB3A if you don't have any kind of load on it.
Did this on with my Milwaukee 4ah and it mever worked again after going flat tried trickle charging to revive neber worked again dont know why ?????
