Thank youuuuu i thought i was going to have to buy new batteries again!!! I bet this is what happened to my last ones!

For version 2, you need to reinforce one side so that if you want to hang an inverter, you can without worrying about the weight.

Great video, thanx!. A question, to wake a LiFeP04 24V lithium battery, can I still use start battery of 11-14.6V or I need a battery closer to 24V?

Ultimate UPS ,,, and customized server rack install... impressive video...great thinking...

why did you do 13.8 for this battery?

Thank you for another great video

Just what I needed. Thank you 👍

I use the lab power supply to charge my lithium motorcycle battery completely. Works great.

Junior was a legend addition to the GT and Giulia. So it's a great name for that Alfa.

Could you make a similar video using a dieless crimper like the TH0020? Would love to see a comparison of the finished crimps. I really appreciate your videos! Thanks.

I ride a motorcycle and it has a Lithium Battery. I also have a Lithium JUMP PACK. The Jump Pack says to NOT USE ON LITHIUM BATTERIES. How do I jump start my motorcycle with its dead Lithium battery? Is it OK to just attached the JUMP PACK for a few seconds and then remove the pack and see if it will start?

You are actually telling the charger there is a battery at the other end of the cable. A 9v battery will do the same thing. The charger needs to see current even a small amount will allow the charger to start.

My new charger has a wakeup mode where it puts out a selectable voltage for 5 minutes before sensing for recharge

thank you, thank you, THANK YOU....for the info AND for NOT making this MOSTLY ABOUT YOUR FACE.....like so many, many others...um...yeah...thanks for that...for reals

Thank you.

Does this manufacturer have 5kw or 6kw series?

Romex in an RV? Not a best practice, even though cheaper than the good stuff. Use ferrules and you don't have to fuss with the screwdriver. This video actually damages your brand.

You should use a diode between your power supply and the battery to protect it from being back fed by the battery charger. Without the diode you may damage your power supply while trying to wake up the battery.

Not so with me; you may read my (reply to comment below); from 3.200 to 3.330 you have 130 points to id the SOC,and that is enough; i disregard all methods, except the VOLTS; of course, i correlate to the amps (in ,or out, or near 0), and then, Volts are SOC; i am so used to my 40 cells, on a 48 volt setup, all used, mix and match!!! working well for 2 years, i kind of know them all 16 arrays,one by one now.

So can i hook up 2 chargers to the battery to make it take a charge so my main charger can start charging it?

For some reason that first window with the general tab and all the info doesn't open for me. I have an MK3 instead of the MK2 that you're talking about, could it be the problem?

I was following advice to condition a new LiFePO4 battery by charging it to 100% and then discharging it completely. My heart stopped for a moment when my charger wouldn't do anything, and my multimeter showed it barely had voltage. I knew the BMS was doing its job and cutting off the cells at low voltage, but this video reminded me of an old reviving trick. I never would have thought of this trick as an easy way to fool a charger and get things going again.

What about if you have five or 6 V no battery maintenance system and it should be at 14.4 - 14.6 how do you get it back to that?

Not sure what the point of insulated tools if you touch the battery post anyway?

Just buy a victron

I'm about to try this with a Rhino 3

life saver!!! the best instructions ever

Im glad this helped me out. My Renogy battery was dead even though it was on a solar with mppt from them and still died. They wouldn’t help me and came across this. Got it jumped started and now charging through my NOCO Genius charger

So... My Cerbo GX blew up. I reversed the polarity and turned it on without noticing. Upon disassembly, I discovered they have bodged this capacitor to where the protection diodes were supposed to be. It blew up, releasing lots of electrolyte on the PCB. Other PSU components, inductor and ceramic capacitor, have been blown off the PCB. It is very unfortunate that $300 device is missing the simplest protective measures, given the conditions it's supposed to operate in. A photo of an undamaged PCB would be greatly appreciated, as sending device for repair or ordering a new one is currently unfeasible :(

Hi, great analysis, very helpful, thank you. I want to set up a system using this inverter charger with the Smartsolar MPPT 450/100, do I need cerbo GX communications set up with it or can bluetooth do everything the cerbo GX can do? Thanks for any help.

Hi have you change the boards for i-moble 48v 100ah battery?

Thank you

Great video! Wondering if it would be a good idea to put ferrules on the end of the wire?

Just got not one, but two bad ones. 3k 48v MP2's. They have a 25Hz PWM fan rattle that sounds like an old dodge diesel motor. Horrible noise. Now I have to fight with the dealer to get them replaced. There is NO fix as its a bad motherboard, not bad fan. Victron continues to sell these with bad 25hz pwm and they know its a problem.

With all the technical talk I really wish you could’ve slowed down and actually explained how to do a charge with another battery.

Important to put an insulator between the cells preferably epoxy fibreglass sheet as the casings are live and the thin blue plastic is not enough to be a reliable insulator

I did some tests on the efficiency of the battery charger ( a Multiplus) 12v 1600, when charging a li battery at 50 amps, measuring watts in and watts out, efficiency was only 73% ( certified instrument) which I think is poor, however the power factor was 0.998 so good for running off an inverter generator. I will test my 48V and see if it is any better. I done like wasting 25% when I am camping and charging from a Generator. So i built for comparison, a 300-watt toroidal transformer rectifies with ideal (mosfet diodes) and 8-gauge leads, this was 92% efficient 0.94 power factor unregulated but when I am camping I only use it with my 1000watt Yamaha inverter generator and I do not charge more than I need to ( solar is the main)

Thanks Dexter, good stuff. There needs to be more videos on the internet like this! 👍

Very informative video, thank you. Is it possible to find out if this unit is built/assembled in the U.S like other Midnite products?

can i use a 36v bulb for a 48v battery?

Super video thanks it helped me to start my brand new lifepo4 battery

WHAT THE..! Recommendations without saying why. BS..! If your gonna act like someone who supposedly knows what they're doing, FILL IN THE BLANKS. Don't leave people guessing. If it runs off of one battery, add a disconnect switch on the positive lead and move on..

Great video however, as a professional pipe fitter, I have very limited knowledge of electrical circuitry and could use your advice on a project of mine. I am attempting to build a portable power supply and will be limited to complete it due to budget constraints. I have the box for equipment, a 12v 100amp LiFePO4 Battery, a charger, a few fans for cooling with thermostatic control and thanks to your video, I will be purchasing this shunt. my question is, where do those red and black cables (I assume power out) go? I am only trying to power a 12v dual zone fridge for now. Let me know. Thank you.

device is such expensive and no even bluetooth there ! crazy

So would this be better for a 50amp fifth wheel than the mulitplus 2x120v? Trying to see what would be best inverter for our RV since we have a residential fridge and 2 rooftop ACs.

But how long will it push 60a?

Over amperage. Over limit. Until the induction coil says so.

Good man, good job done there. However I'm slightly concerned about this kink in case the radius of bending is lower on a lower quality CCA type wires which have flooded the market. IMO I'd like to put a ferrite ring over there and wrap the cable around it achieving two goals at once: Stoppage anchor in case of pulling the wires accidently and noise filtering which is present in all electronic equipment.

I'm impressed, normally I'm not a fan of all-in-one units but this one is quite nice.

Bro shut up so we can hear
