I didn't know anything about batteries or cells or lifepo4 7 months and then I decided I'd like to upgrade my batteries in my RV. So watching videos reading information here. I decided to jump in 2 feet all at once. I ordered from Jenny Wu and mentioned Ray's name. I got 4 280ah 2800k cells for...

Yes. Shipping and tax I paid $600 for 4 cells..there was a card fee where the total came to $617 Docan Tech EV LF280K 6000 cycles lifepo4 3.2V 280Ah battery from Jenny Wu

Son got one of the cell holders printed. Now to take the battery apart to see how it fits.

Thank you for not talking down at us beginners.

What exactly happens when you crank your generator? I have a battery I built with 150 amp BMS which has no trouble turning over my Onan 4K. Which 100 amp hour battery did you buy? When the current from the alternator turns off then you will not have back feed through the dc2dc, it's a one-way...

Just wanted to update this thread since I could barely find any information about a lithium battery starting a onboard RV generator. I built a 280 amp hour pack with a 150 amp JBD BMS hooked it all up and fired up my generator multiple times with no problems. Using the Bluetooth app for the BMS...

Looking at a 2000w inverter and the two I'm looking at are the GIANDEL 2200W Pure Sine Wave and the WZRELB Reliable 2000W Pure Sine one has a terminal block for high power appliances plus two standard US plug in's The other has only two standard US plugs Question: Using a heavy extension...

Thanks ..I'll just have to do some actual measuring instead of just thinking about it. My son is the 3D printing guy and he said this is very doable and looking forward to me getting the measurements for him. We might be doing a Renogy type color scheme

OMG! Just sent 3d printing enthusiast son the link to tweak your work for my 280ah and 150 JBD...Bye Bye Plywood!!!

Yeah he's a wiz with the printer. Made me a RV bathroom cabinet latch that broke He printed one from scratch. I'll post the progress when we get something

Okay " lamp" this slang is going to kill me. Haha I will find something to rig up to make this simple test lamp. Thanks guys for the concern and help

My giandel 2200w inverter draws about 1.5-2.0amp from battery on standby, around 22watts

Current connected has the JBD 150a in stock looks like, otherwise you can get it in the other link on I posted from China and hope it gets to you in a timely manner https://www.currentconnected.com/product/jbd/ Overkill has the 120a model only

Will who is an Admin on these forums makes videos. Here's one that will help you on your decision for a inverter

oooOOO!! yes! here's to hoping you like what you print.

to answer my own question I went with the Giandel with the terminal block (& 3 yr warranty). Looks like I can draw more watts out of the block then just out of the single socket.

Not sure I would budget on the BMS. You would want a quality BMS for you investment.. NO? Am I being a jerk?

What are they size of your 304ah batteries? Are they not the same size as the eve 280ah?

If you can find someone with a 3D printer this guy is sharing his box build with the same specs as you have. 304ah cells with a 200a JBD BMS. I would look into it Thread 'Battery(300) Design Open Sourced' https://diysolarforum.com/threads/battery-300-design-open-sourced.34832/

Good Point! Alot easier to add spacers if my pack is smaller. Son was telling me the thing he was worried about was that if he had to stretch or shorten it it might skew the holes for the rods and or the screws

Ran into a snag. My terminals are too wide changing the parameters completing messes up the case parameters. My terminals are 25.4 mm from stud center to edge

Son is printing the first cell housing now and will bring it over this weekend to see if we need to do any adjustments. This is going to be a long time in the making since we only see him on the weekends.

@bryn When your done do you think you could share your design? Looks like you have the same issue with the studs being out closer to the edge as I do. I would redesign myself but son is the one with the printer and I can only ask him to print and not to take his time adjusting for me. But this...

So I'm thinking I should go with an ANL fuse. Is that a slow blowing fuse?

Damn! All these new tools I'm buying..lol. hopefully I can use them again. I'll go this afternoon and get one and give you a boots on the ground report. Thanks!

They match..but here's my head scratcher When I test the line and neutral together I get 120v. When I test the line and ground I get 66v I test the neutral and the ground I get 54v Why is that? These measurements are at the inverter terminal block. Shouldn't I get 120v from the line to the...

Yeah this mobile inverter stuff made my head hurt all day. Not sure if there is a inverter that has a terminal block with a neutral ground bond that I have found. I would return this and get it of someone has a recommend. I did watch a grounding video Will mentioned in his inverter video...

good to know. thanks for speaking up

Okay. I will find out but I'm dumb and don't understand this " Can be bonded to the safety ground or not" Is this something I can do with a meter? Sorry I'm a idiot when it comes to this. If you say connect this to this I can do that. Lol.
