HUGE Battery Box for Off-Grid use from AMAZON

[@kimmer6]

I built 6 battery boxes for friends and family using modified Minn Kota battery boxes and 100 amp hour ToBattery lifep04 batteries that come shrink wrapped with attached BMS and without battery cases. These are very compact batteries! The 100 amp hour batteries are small enough to fit 2 of them inside your battery box with foam padding! ToBattery also makes a slightly taller and wider 200 amp hour battery which I installed in my personal Minn Kota box. Imagine having 200 amp hours capacity in that box! The other thing I do is to add a BesTek 300 watt inverter on top of the box that gets attached with Velcro strips so that it can be removed for use in the van if needed. I swap out the 10 amp circuit breaker for a 20 amp unit, add bigger wires, retain the 60 amp side terminals. The box gets a LED trouble light, battery isolation switch, USB dual port outlet, standard lighter outlet, and voltmeter. I buy Chinese voltmeters 6 at a time and maybe 2 will read accurately! The other thing I do is to add removable lugs for the side terminals so that jumper cables can be used to recharge the battery somewhat if its raining, no solar charging is available, and I need another 50 amp hours or so stuffed into the battery from the van's alternator. I started building these battery boxes in 2017 to run CPAP units so my friends could sleep thru the night after wildfires caused our outages. PORTS!

[@JohnDoe-zg6fn]

I love all those PORTS and the different options these boxes have. To be honest, I didn't even know how far these things have come. I remember all the old school ones you can put on a boat, but nothing like these. Thanks for another great video, sir!!!

[@brianhendrix]

That is the exact box I use. I keep two 12V 24Ah batteries in it along with a LOT of Anderson Powerpole cables -- lots of room. The batteries are: TalentCell 12V 24Ah LiFePO4 Battery Pack LF4040, 12.8V 288Wh Deep Cycle Rechargeable Lithium Iron Phosphate Battery I got those because I like the battery check button on them. And, yes, I heard PORTS!

Thanks for sharing

Ports…new to the hobby. You put out great info for us new hams. Enjoy every video.

[@HamRadio2]

Thanks!

[@seanihde]

Ports - you need to add a shunt to get correct voltage of lifepo4 battery. They run at nearly full voltage until they are dead. I like the Victron Bluetooth version.

[@kimmer6]

I have had great success with the Renogy $85 shunt and battery meter. I must have 6 or more on my projects. I have the Victron unit but for some reason its Bluetooth does not have the power to send to my cell phone from the garage to the house like the Renogy units will. I now use $45 Amazon ''pet cameras'' to view the Renogy battery display from anywhere I get cell phone reception. The heck with Bluetooth! Regardless....running a Lifep04 battery without a shunt type battery State of Charge meter is like driving a car with a broken gas gauge. I make up copper lugs to attach to my battery boxes such that in an emergency, I can use jumper cables from my running van to put some charge back into the battery pack. It's not ideal but I tried it and it works.

[@cmhuggins29]

I just bought this with a 12v 100ah renogy battery. This is cheaper than a jackery for my truck frig. $300 all in parts.

[@bob.kd9idd]

You can never have too many ports. I currently have the Gigaparts Explorer Box(I got it because of your video) with Buddipole Powermini 2 solar charge controller, a Eco-Worthy 20ah Batttery and Harbor Freight Thunderbolt 100w solar panel brief case. Everything works great together. I am looking into upgrading my knowledge and skills with powerpoles and 12v appliances and gadgets to start tent camping with ham radio this spring. I like the battery box from amazon and will consider it into my collection.

[@onesimusiii]

So you like the buddipole mini charge controller?

[@onesimusiii]

Is the eco worthy a lithium battery?

[@W5ERX4911]

I am using the Explorer box based on the video you did on it. It's got all the "PORTS" I need and holds my 30ah Bioenno battery. I also plan to add solar with a charge controller added inside. Take care!!

[@johnwilson9303]

I also purchased a similar Box from Napa on sale. I added fuses and an AOLithium 100 ah battery. I'm a little dissatisfied with the buckle on the strap as it failed when I 1st picked up my battery Box with my battery inside. I am still working on a solution for a strap I can trust. Other than that I'm very satisfied so far. I think I will keep my PORTS unchanged for now.

[@HamRadio2]

Turn the strap upside down, that is what I did. It holds pretty well that way. I also have a 100AH AOLithium battery that I am testing.

[@georgederocher8202]

Which cables did you fuse??I just picked my Maxi Trac box from NAPA today, on sale for about $45. Had to order it. I’m no expert at all, but I’m thinking since the USB and 12v port are on the 16 amp breaker, I might just fuse the Anderson lines . They will be used for DC to DC charging, eventually fridge and solar charging, although I might just add a fused SAE line to match my Renogy, or an adaptor for the Andersons. Right now it’s primarily for using my CPap for sleeping in my truck with camper shell, charge back up with solar until I get power run to the bed. Or, I could just inline fuse whatever device I have ….Looking to find a budget 100aH LifePo, not worried much about heating in South Texas. I can always add a pad . I avoid cold .

[@kenluning909]

I have built a HAM Radio battery box and it is pricey to buy all the components and a good box. But it was a good learning experience as I now want to build a 2.0 version. PORTS

[@CatfishWeekly]

Great video! I make my own boxes because no one puts more that 1 12 volt cig plug on them. The reason I need more that one is because I have 2 live bait coolers on my boat and that is how they are wired! I would love to be able to purchase just the empty boxes in your video!

[@dougwilson8274]

PORTS, got to love them.

[@soonerarrow]

I'm just doing continuing research on battery boxes and DIY ideas for solar chargers with plenty of _ports_ .

[@josephw4elt386]

For me, when it comes to ports, its all about the powerpoles. A usb or 2 are useful, but they can easily be provided by an attachment plugged into a powerpole. Bonus if the box is big enough to store that inside if not in use.

[@808pathfinder]

When I found the bigger setup I bought two n now I can link my batteries together at the same time hooked up to solar panels and two inverters all together and theres different types of sizes of batteries so some might not fit, I use 12.8v 100a lithium LiFeP04 in both, love it n worth getting, 808 back out

[@KU9L]

Nice Ports Jason! The 75-amp Anderson connectors work best for using a DC-DC converter to charge LIFEPO4 batteries from the truck to the travel trailer as quick disconnects, works great! In ham radio, you would be QRO+ if those fuses were not just 35-amps. I have the Explorer box and have 12-AH of LIFEPO4 batteries Plus the 100-watt solar panel you recommended in a recent video, works GREAT for QRP and I am QRPppppp with my Tuna Tin Transmitters. The Explorer is overkill, but I also bring out my WA3RNC TR-35 when I feel like some 8W QRO, LOL. The Explorer box was great and would have been better if they made it group 31 like your featured box here. Cheers es 72, Dave - KU9L

[@michaelconner5422]

i got the same box from napa on sale last month. it is still available for 15% off on the site. i do like the ports on the smaller box though. and will be looking into getting one of those for my smaller miadi battery possibly, but if you want to do some wiring you can fit 4 of the miady 20amp hour batteries in the bigger box. i like the idea of putting more power pole ports in it or adding the smaller power poles to the large ones. making it more useable for the ham users.

[@Obeeewaan]

Ports are important.. usb/usb-c, and one lighter style plus several power pole are what I have in my homebuilt toolbox style battery box ..

[@Jagrrr]

Ports. I like them both, even at retail.

[@rollandmason5596]

That Explorer box looks like a good match for my Bioenno 20AH battery. I like the PORTS on the box over the larger one. More useful. I also have no need for the "cigarette lighter" socket either. Great video. Thanks KJ6DQ

[@longrider42]

Yes I like lots of "Ports" I built a small battery box, using a 12 volt, 6 amp Bioenno battery, but then all I run is HT's in the field. I now have a Grecell T300 Solar Charger, and the 100 watt solar panel that goes with it. Its got one 110/120 plug, with a full sine wave inverter. Three USB 3.0 and one USB C. A 12 volt plug and two 5521 plugs, that I picked up cables that end with a 12 volt plugs. So I can add more USB if I need too. It is a tad heavy, but it has the inverter and the solar charger built in. So its all good. Have a good one.

[@carloshonestopinions]

Word of the video - Ports! Thanks for the video, but I was hoping to get more information on this battery box, which I just ordered on Amazon. I plan to put an old car battery in it, and if this works, buy another box and have a dual setup for my RV. Does it have a charge controller for solar, and how do you charge the battery (I assume with the outside connectors)? Are the Anderson plugs for energy output or can they be used as inputs to charge the battery as well? Sorry if the questions are dumb, and I probably should have waited to get my box, but I wanted to acknowledge your video! Cheers

[@HamRadio2]

No charge controller Yes you can charge with the APP connections, they are input and output.

[@weasleyoc]

Ports. I use a Powerwerx battery box, the smaller one with a 35 AH AGM battery (plan to swap out for 21 to 30 AH Lifepo4) and a DIY 18AH Lifepo4 made from a 30 cal ammo box from Harbor Freight. I built it about 2 years ago and it cost me around $150. The battery pack being the largest cost, around $65 from Aliexpress.

[@bwraith]

Oh man Dem Ports! Yeah i made one of these and modified it a bit. Went your route with the power poles but i replaced the volt meter with a qc3/2x usb-c socket. I have a renogy battery monitor on it as well for accurate readings (major overkill). I have my miady 100ah lifepo4 battery in it right now and it's just the perfect size.

[@lesterwillison38]

i need to see about getting the anderson PORTS, just getting into the hobby..

[@kimmer6]

Anderson connectors come in different colors. BUT... they do not interchange! Yellow fits only Yellow, gray to gray, red to red, etc. I found this out the hard way. And the Chinese knockoff ''Anderson type'' don't have quality control. The little spring spades inside the plastic housing are often not long enough to push the contact out far enough for proper engagement when you plug in the other half of the connector. I went through a bunch of the knock off connectors that disengage and snap apart if they are bumped. I ALWAYS jam the spring spades forward when assembling a connector and melt the plastic with a soldering iron to keep the spade locked in place. That way, the contacts engage properly, amps flow as designed (no overheated connectors), and you really have to grip and wiggle the connectors to disengage them.

[@nc4tn]

When Walmart closes out 12V game feeder batteries in the spring, I buy and install in my boxes.

It was my primary vehicle. The box I have in mind will have room for an EFHW HF antenna for field use. If I can work it out, there will be a mount for a QRP radio. If I can see how to build a line of boxes, I may get into the high dollar HAM radio accessory line. Yes, I can be delusional from time to time.
