    • It’s best to keep these things secret sometimes. The guys who sell the used batteries realized they can charge a lot more for them since they happen to be 90% of new capacity. I mean, wouldn’t you?? It’s aggravating but sometimes putting stuff publicly online kills the thing. Share with friends and family. Good life lesson. Same thing with great hiking spots or low key camping spots. If you make a public video it will draw the tourists and all of a sudden your never-crowded sweet fishin’ spot is overrun with people. Keeping things secret is a good idea sometimes.

    • @countryside Good luck with those, and expect about $10 per amphour. There are only one or two sources for them. And for RV living they are (in my opinion) not an option.

  • Well my question when watching your video was recharge time. How much power do you have to supply for how long to recharge them? And if they need futzing with when they discharge below 10volts that's kind of a problem, no? Also I come from the Solar Generator side of the business, where amps are more the constant like in household power, rather than a main source of reference as in RV or automotive oriented systems. If you could do the conversion for us it would help. For example my new solar generator specs are - The Ecoflow Delta 1300 provides 1295 watt hours, 1800 continuous watts/3200 peak, has a built in MPPT Solar controller and can be recharged in 4 hours with 400watts of solar panels 12-65V 12A max, or in 1.7 hours from a 90-140Vac 1200W source. They weigh 30lbs, you can chain up to 4 units, they use lithium ion cells and produce a pure sine wave..." Which BTW - right now they are still $1199. A 4 hour recharge time with solar is a game changer I think, especially as you can charge them while you use them. You could build a small scale home system for off the grid living for under $5000 that, with a careful choice of appliances, would not be so different than on the grid. And when there is no sun you could pull out your gas generator and charge up the whole system in two hours! Kinda like a hybrid car. ;)

  • so I have a question. I bought 4 of those Valence XP U27-12XP batteries they were used (they all only have about 200-322 charge cycles on them.) I also now have the AIMs PICOGLF25W12V120AL inverter charger. I'm charging my bank and it seems to have stayed in float charge over night and it doesn't seem to charge past 13.54 volts. I did set the dial on the charger to "flood lead acid" which is option 4. what could be the issue? is the charger bad? or could it be the batteries?

I have a question for you I’m building a Florida flats boat and want a lithium battery for my house battery to run livewell, lights, radio, and a trolling motor that draws 40 amps on high power. I have room for a group 31 but don’t want the weight. I also need to be able to charge the battery when I get back to the dock. What would you recommend? I know I can pick most any lithium battery, but can I charge with a standard charge or do they require a special high volt charger? Thanks. Again keep on making videos, they are awesome.

  • Hey @Will, I have a (Actually 4 of them) 250AH battery I purchased off of Ebay. You can look it up with search on EBay and I'm certain you'll find it. Company is called dagastore, I believe they are the retailer for these Chinese-made units. Anyway, One of the batteries died. Not sure who is at fault but I think just the BMS gave up. Any suggestions on trying to get this unit back on-line? They replaced the unit which is great, but now I'd like to know if I can salvage this thing. Happy to PM you if you're ok with that.

  • Maybe I'm missing some information here but are you using two batteries in parallel to achieve the amp hour rating of one? If you are using two in parallel you should be getting double the amp hours as a single one. That would put them at 45% of rating. Maybe you had that already figured in to it and I just missed it.

  • No wonder I can't get these for free anymore 😔. I have 100 in 10 banks of 10 in series in my heated and cooled generator shed connected to 4 very large 30amp output commercial APC UPSs connected in parallel and run into a mains panel. Then a 10kw generator running to "FULL BRIDGE RECTIFIERS". lol. to charge the batteries. I have to start my generator just to make sure it runs these days. I work in E-Waste recycling and I built all this on the super dirt cheap with the help of my local utility company installing the proper mains switching contactors so I can't backfeed the grid. I'm on grid but I have many extended outages (days) throughout the winter. I can go off grid and even run my baseboard electric heaters for a short time without even knowing it happens. I use the built in relay outputs from the UPSs to shed unnecessary circuits as my batteries drain and outputs from the ups network cards to start my generator, monitor the banks, and text my phone when I go off grid and return.
