People say MY videos are shakey. I think you’ve got me beat.

I always use a pre-charge resistor when I connect a battery to my car for the same reason (!)

For camping purposes, can I use the small propane talks? Do I need a lifepo4 battery to power it? Will it work with a 5-gallon tank?

@proficient_prepper Can you please test the unit and reply here with the results for when the unit runs on battery, fully exhausts itself (like an all day power outage), and when power is restored by the power company does the unit AUTOMATICALLY turn on. There's nothing more frustrating than being on vacation for a week, realizing your UPS doesn't auto-turn-on and you are down for a week instead of just a day if you had not had a UPS at all.

Duh, then what? Is that it? Don't run with sissors?

Thanks for the video! Very informative. Regarding a 48V system - - keep in mind that a 48V system requires a very high minimum input voltage. You may not have enough solar panels and/or enough real estate to mount the panels.

Is it safe?

Se pueden conectar 2 baterías en serie Para obtener 24v?

Minis should not be paired with non minis , they have different cells and charge ,discharge, differently .

Hi could These batteries be use in a electric car, since you don’t need the cranking is used just for lighting and accessories I think, and the BMS should take care of the charging?

Cons: cells don't have case.

I just got a couple of these on black friday, my first lifepo4 batteries, but they seem to work great charging with a victron MPPT and running a 2000watt inverter!

Would this battery be good for a trolling motor?

I appreciate this video. I am debating between 12v and 24. Starting to lean towards the 24. Can I ask do you have anything that runs on this system all the time.

I'm thinking they should just make all these LifePo4 batteries as minis. These batteries are not put in vehicles where they need to be certain sizes. So I can't think of any reason they just don't make them all as minis. What do you all think?

You should have ended the short with the pre roll. It's was far more exciting.

Have two 12v 100ah , 3 months no problems.

Thank you for taking the time and energy to film this video. Both interesting and easy to follow.

Lol but it is true. That is no joke. It’s absolutely vital to staying safe and protecting your equipment.

I just connect the positive first and then negative. Never had a problem.

Just some help to those that have this unit or want one. I have had no issues with this unit in the 6 months owning one. They do have a nasty smell for about 1 month, so keep that in mind, but it smell goes away. The one flaw that happens with these units is brown outs, some not all brown outs can cause this unit to not switch over. Usually this seems to happen with Brownouts in quick secession or small blackout that last 1 second and then another right after hits again. These are the only instances I have had this unit not work as described. I think what happens is the software gets confused with such a low drop yet not fully disconnected, I have no idea if ALL UPS do this under these circumstances but this unit does. But every actual power outage or breaker trip and the unit does what it says. I really recommend this unit for the average PC user.

you should never use rubber type gloves for electrical jobs

I built -48v DC power plants for 20+ years . Carrying thousands of amps . It doesn't just shock you , it cooks you from the inside out . Amps is what gets you .

They should call those connectors “hermaphrodite connectors” and each should be consulted with to determine which sex they want to associated with … such as male dominant and female recessive or female dominant and male recessive or “I would rather not respond to those labels”. Let’s keep it simple, and this will make life less confusing. 🤷🏼‍♀️🤷🏽🤦‍♀️🤦

😢 48 volts 😅

😂😂😂😂😂

Discount code not working

So you’re grounding it with a resistor to drain the capacitor(s)? Not charge them correct?

That is wrong. The maximum system current is the module short circuit current times 1.25. When you get the result then you can consult the chart for the correct size wire

just the info what i was looking for,thanks

I don't use a resistor. I just connect the circuit at the battery this way the wire consumes some of the current.

Great review

The proper term is Discharge. Not charge... Not precharge... You want to discharge the internal capacitors, by holding the ceramic housing of the resistor, and touching one lead of the resistor to the negative terminal of the inverter, while at the same time touching the other lead of the resistor to the positive terminal of the inverter.

My Eyes...

u need a fuse on the red cable to the inverter.if u get a short in the busbar the inverter cable is not protect.

Hah

That resistor should be pre install from factory in the first place 🤦

How eould you geound such a setup. I kean how eould you ground the PV side and the Battery side?

I installed a 4 breaker transfer switch into my garage using my solar generator to offset my power usage. Trying to get the courage up to install one like this in my house to offset power usage there as well. Great videos keep them coming.

May go bless you for teaching how hooked solar

Great step by step video for less knowledge DIY 👌

What do you think about using this battery for other than marine uses? With its very high amperage output, it would be useful for many things.

Quite nice way to be able to move the panels for better position away from shade.

Thanks for the video. It really helps those of us how are curious about building a similar setup without the experience!

The #6 gauge wiring recommendation from power queen is only sufficient if wiring batteries in parallel to increase capacity but not increase charge/discharge rates, if planning to draw more than around 120A from the system you should really be running AT LEAST #3 gauge wire to connect them. Best practice is to just use the same wire, but at minimum the wire should be thick enough to handle half the overall current (if you discharge the system at 140A, the battery interconnect is carrying 70A from the first battery, then +70 from the second battery). You should still use the same wire either way though because if one battery BMS cuts off for some reason it can leave that wire carrying the full amperage until the second BMS cuts off.

I dont think your precharging the capacitors, but discharging them with a resistor.

Actually low frequency inverters are more energy efficient, your idle draw is higher because this is in inverter charger

Hi, can this battery be charged by the outboard while the boat is moving? The output voltage of the motor is 15A! Regards, Julian

lololol
