Starting this thread as much to document my install as to share with others, but I’m excited about the progress so far today. I dare say, the hard (heavy) part is done! 4x 300Ah Epoch Essential batteries with their matching mounting plates in place. Next is to decide if I’m going to wire them...

I've read about and followed many of the threads regarding lithium battery upgrades. I'm convinced of the advantages and want to move forward, but I just don't think this is something I can undertake on my own. I'm looking for a qualified installer or upfitter in the Portland, OR Metro area. I'm...

‎ WattCycle 12V 100Ah LiFePO4 Battery (Group 24 / Group 31), Model WT12V100AH-CSB I live in the North Seattle / Shoreline WA area and prefer pickup within this area. $80 cash or best offer

Like many others, we upgraded to the new "Auto-Detect" version of the WFCO power center, only to learn it couldn't detect our new LiFePO4 battery. It wasn't a major problem because: 1) we have a solar suitcase with a LiFePO4 charging profile to use while dry camping; and 2) if we have shore...

I just checked in on Lithium battery (LiFePo4) prices on Amazon and what I found surprised me... The last time I checked (fall '23) in on "cheap" Lithium battery prices they were around $259 for a 100ah 12v battery. Now they are around $199 with free delivery. There are several brands at this...

Hi all, That age old question - I am looking to drop in some LiFePO4 batteries into my 2014 Jayco Flamingo with a Voltech ISC 3040 MPPT solar charger. Wondering if I can get away with using this controller or do I need to swap it out for something else with a lithium charge profile? Or is it...

Peek behind the refrigerator. Outside vent has been plugged with foam insulation. None of this stuff needs to be accessable. Electronics consist of: 280ah LiFePo4 battery with Bluetooth BMS Trickle charger for starting batteries Xantrex freedom 1800 HF Charge relay for alternator charging...

Hello I recently purchased a 2022 imagine 23LDE and I went immediately to modifying it. One thing I did was add two 200ah Lifepo4 batteries. I also bought a 2000 watt inverter. My plan is to run the invertor and dog bone it to the 30amp cord and then plug that into the back of the camper...

I'm transitioning my trailer to 100% lithium. I added two 100ah LiFePO4 batteries dedicated to the inverter and had previously been only been charging off the solar charge controller. Now I have purchased the 300ah Chins Smart Battery with internal heater to replace the two 6 volt flooded lead...

We are in the process of making a deal for a 2022 Jayco 199MBS and it indicates it is prewired for an inverter, so I have a couple of questions. First, where is the prewire location and is it "plug and play" so to speak? Second, I plan on using LiFePO4 batteries and wondering if anyone has...

The lithium batteries are LiFePO4 unless I am sadly mistaken, and as far as I know they don't take kindly to attempts to charge them below freezing. My 21NE has those outside in the utility chest near the hitch - how worried do I need to be about that? Is there a low-temp sensor? Does it have...

I am in the process of converting my 2022 Transcend Xplor 247bh to LiFePO4 batteries. I decided to put them under the front bed (not interested in discussing the placement). I switched to this Progressive Dynamics lithium converter from BestConverter.com (who were awesome to work with by the...

In several threads the question of how to properly wire batteries in parallel has come up in the discussion. I have found a study that explains the advantages of various wiring schemes when it comes to wiring batteries in parallel... Here is the quick explanation: According to the study linked...

I have a 2006 Jayco travel trailer with 30 amp IOTA Engineering charger/converter/load center. Recently I installed two Renogy 200 watt solar panels with controller, monitor, inverter and 100 AH LiFePO4 battery. This system is presently isolated from the existing lead acid batteries and...

I’m considering replacing my two AGM batteries which no longer go above 12.5v…. with three 100ah Lithium batteries with a five-year warranty. https://amazon.com/LOSSIGY-Rechargeable-Lifepo4-Lithium-Maintenance-Free/dp/B09FLXQF5B/ref=psdc_15745581_t3_B093L622N9?th=1 . The only downsides I see...

Hoping this will catch the eye of some folk who are experienced with Lithium. I bought a 2018 MB Sprinter 2500 with a starting battery linked to 2 under-carriage AGM 6v cabin batteries, wired serially for 220a 12v and a 1100w inverter. Built in California, it only had 1 solar panel atop...

Hey all! Got a bit of a weird one (at least for me). I recently made the switch over to LIFEPO4 batteries and also installed a PD9160ALV from Progressive dynamics. Everything has been working fantastically so far. This weekend I finally installed a battery monitor so that I could see what the...

Can anyone give us some real world experience regarding how hard our 12v fridge will eat at a battery? The label in the fridge says 11 amps and the chart I was referencing said to multiply that times the hours of use for a total. But that can’t be a true realistic expectation since the fridge...

The following is in response to a question on the Electrical Wiring forum. Since this topic is of General Interest, I thought I would re-post my response here in order to let more people see it. The Question was: Can you install your Solar system in phases? Here is my advice... Yes, building...

Hi, so for the last several months of our buildout, I had been planning on getting 8 Duracell 6v GC2 batteries. I kept checking Sam's Clubs website and availability was concerning me. DIY LiFePO4 batteries are also comparatively reasonably priced. Sooo I bought 8 304 AH EVE cells (approx 7300...

For those adventurous souls who are considering building your own Lithium Battery (LiFePo4) bank, a company named Sun Fun Kits has put together a complete kit to make assembly easier. The kits include all the parts you would need to source individually, Battery Monitoring System (BMS), battery...

Okay, so for the past several months I was planning on getting 8 Duracell 6v FLA batteries in a 4s2p system for a 430AH 24v battery bank. I recently discovered that there are ampere, chins, or zooms LiFePo4 batteries that are only about 1.5x the cost for the added benefits that LiFePo4 has. I...

Hello, newb here. My SMB build called for the large, ReLION 300AH underbench battery. To my surprise, they installed an outside vent for this compartment, which besides the lithium ion battery, also contains the 2800W pure sine inverter, Victron 35A MPPT solar charge controller and 712 shunt...

Greetings all! I have 4 x 8s/24v batteries that I put together, with each set of 8 cells attached to a BMS. I accidentally tripped one of the battery breakers manually (i.e. it did not trip due to an electrical fault) when it was depleted. Now, it appears that at least one of the batteries...
