Anyone got one on a shelf they dont need? Message me if you do. Thanks!

Simple question (I hope): I have a 190AH 12V LIFEPO4 with a BMS rated 60AMP discharge and 30Amp charge. It is connected to a new 12 volt 2500watt pure SINE inverter (peaks at 5000). Between the two devices I am running the same gauge wire as the BMS Negative wire. The Plus connects to a 40Amp...

I use a Guest chargePro to charge 3 banks on a boat. Looking to leave lead acid for starter motors but go LIFEPO4 for “house” battery. Can this work? Home built 75AH LifePo4 battery does not need to be 100% optimized. Thanks as always!

I have two 100watt flexible solar panels from fleabay that stopped working and of course the seller is MIA and unresponsive. Hate to throw them away. Both panels have fried diodes ... can these be replaced by someone with limited soldering skills. Thanks for your ideas/recommendations.

Working on yet another budget LifePO4 project. Goal is to have more 12V capacity for a small room air conditioner and use the battery packs I have. I have Three (3) 12V battery packs each using the exact same BMS (each). One Pack is 175AH, one is 75AH, and one is 50AH. Batteries are different...

Embarked on a project during Covid to convert a Promaster Van and have it be all electric - no propane, no gas generators, and as simple as possible. Having zero solar or LIFEPO4 experience I relied heavily on this forum to design, build, and implement a 24V system to drive a roof A/C (in...

My 20-year old 50AMP 3 Bank charger gave up the ghost last week so I am looking to re-swizzle things on the Boat....add capacity and lose some dead weight. Each motor has it's own sealed acid starter battery and I am converting my "House" battery bank from multiple 6V Lead Acid pigs to...

Happy Holidays everyone! Google is letting me down. Batteries look like EVE280s and have the following on them: 0191H0253190 and 24Q02 Can anyone ID them? Many Thanks! Swampy

I have an assortment of batteries for sale - all holding full charge: I used the 50AH Pack to learn about LIFOPO4 DIY and to drive small inverter during hurricanes. Since then I have built two 280AH 24V packs for my RV and a 12v 180AH pack for my boat. These are left overs I would like to get...

I was lucky enough to purchase 8 280AH EVEs for a great price locally but the gentlemen who sold them to me did not have busbars, studs, or nuts for them (lost interest in project and can't find them). Tried looking for some on line but unless you know the measurements exactly it is a bit of...

I have lost communication to my LV2424 after a couple years of using Watchpower without issue. Not sure if it is a config issue on the LV2424 or the newer versions of Watchpower. Anyone know how to reset the LV2424 to factory setting - oddly I don't see it in the manual. As always Thanks! Swampy

Hello All and TGIF. I have a 24v 280AH battery in my RV/Overlander and am looking to add capacity by adding two 200AH 24v additional units. All three will have same quality 100Amp BMSs. I suspect I should "beef up" the Ground and Positive Busses to accomodate but am having trouble finding which...

Hello All - I successfully built a nice 280AH 24V for my Overlander and will be adding another 400AH shortly and will do it 100% "right". However, I have accumulated a few LifePO4 batteries of various sizes and manufacturors and need a small battery to drive some stuff on my boat - low Amps...

Good morning All! More silly questions from a relative LifePO4 newbie. I have 280AH in the "trunk" of my RV/Van conversion and it can run the roof A/C for about 6 hours (not bad and necessary in the sweaty southeast). If we are boondocking we will need more power capacity to cool a couple of...

Hello All - I have created two battery boxes for 24V 280AH LifePO4s - everything is working great but, alas, I am in Florida and I am worried about the heat's effect on the batteries long term. Can someone recommend quiet computer-sized fans for me - will be running 24x7x365 and are inside my...

Hello everyone. Van project complete so now focusing on the boat. Looking for the following on the "cheap" to complete a few packs for the "house" battery and for a small other project: Qty 4 new or used 180AH usable power (look like Eves) to create a 24V battery - need em to be 5 1/8"x 9 1/4"...

As we all know the LV2424 charger/inverter/MPPT is cool for when we are actively using our Camper Van and need the inverter ... but it uses significant power at idle. When in storage or not being used for a few weeks I would like to turn the LV2424 off and solar charge the 24V battery bank with...

TGIF All. So my 24v 280AH battery bank has been working flawlessly for the last year however I noticed 2 cells seem to charge faster/more than the rest and it shuts down BMS. Wanting them to be more balanced, I decided to dissassemble it, put them in parallel, and top balance them with a 10amp...

I currently have a 24 V volt 280 amp hour battery pack in my RV. I would like to double the capacity however space is at a premium. Is it possible to have the second battery bank be comprised of two 12 volt packs located about 6 feet apart and combined into a 24v pack? There is a small amount...

I have 4x100 watt flexible panels in a 2S2P configuration to either an MPPT Epever or an LV2424 with 300WH 24v LifePO4. Worked okay for nearly a year but solar output pretty weak (flat roof, hot Florida etc.) and never seemed to do what I had expected. Last week I noticed solar not being...

Looking to add to my RV capacity. Ideally 280AH batteries in a 24V pack w BMS but open to suggestions/options. PM me with what you are looking to sell. Thanks Swampy

Hello All - hope this finds you doing well. I have a VAN with 2S2P 100 watt flexible solar panels on the roof. When I measure each string on the roof I get 20-21V each even at noon in the FL sun. I get the same voltages when measure inside the van near the MPPT. When I measure them combined I...

Hello again Folks. RV/VAN has 2S2P 100watt flexible solar panels feeding into a LV2424. Power goes from LV2424 (MPPT) to a positive and negative bus and into my BMS (neg). I also have an Orion Smart DC to DC 10AMP 12v to 24v connected to the two busses (Neg and Positive). When sun shines the...

Happy Holidays all! Any cyber deals on smart 24v 8S BMS100+AMP with cold temp shutoffs? Searching isnt yielding much. Thanks! Swampy

Conversion van has LV2424 (finally working), 2x100Watt flexible solar panels on roof in series, 24v 280AH LifePo4, 240watt 12v to 24v DC to DC converter. Couple of questions: 1) Fridge is a dorm 120v unit running off inverter in LV2424. When running LV2424 plus fridge seems to consume...

Daly 24v 100Amp - need to replace balance cable/connector wires and having hard time finding the part number to order a couple...anyone have a part number or source? I ordered some but too big....searches not yielding what I need. I even tried Will Prowse site but didnt see it. Thanks folks (as...

Good morning All! Picked up a Orion 12/24 10Amp DC to DC Isolated charger. Read the manual twice and want to make certain I have this right before I install. Conversion Van is a diesel with traditional 12V systems. Alternator is a "dumb" 190Amp unit at 12V. Starter battery is a very large...

I need to re-think my RV roof solar panel configuration due to A/C unit encroaching on one of the panels. Does anyone have a healthy Newpowa 100watt semi-flexible panel for sale? npa100-sfm is the model number. I just need one to match the other 3.

Three 100watt flexible solar panels in series - Florida noon sun on a clear day - shouldnt I get 300 watts or close? When I put a meter on positive and negative on the roof I get 50-55 volts. When I measure at the EPEVER inputs fore I I connect I see 55v. As I re-connect the solar to the epever...

Looking to pick up a Victron Orion-TR Smart DC-DC 12/24-15 15A 360W Isolated Charger if you have one lying around, purchased but didnt use....drop me a line. Thanks! Swampy

Conversion Van project has 3x100Watt in series on drivers side and identical setup on passenger side (separate series for when I have a kayak on one side of the roof). Having a LOT of MPPT reliability issues with LV2424 and it eats a lot at idle so looking for a supplemental MPPT to feed the...

Been going through weeks of troubleshooting through China and as frustrating as the delayed email responses and week between replacement parts I am starting to think these things are not good quality...on my third MPPT daughterboard and still no solar input. They are trying but now I am thinking...

Hello all! I have an LV2424 connected to a 24v 8-cell 50AH battery with a Daly BMS. Everything working great last 3-4 months. Today, I noticed the thin ground wire (same size as small red wire to each battery) has signs of over-heating/melting. What would cause this? Red wires all look fine...

Van build continues to roll on and am trying to save as much space as possile in the "garage". Can I put 12volt (4xAmy 280AH) on one side of the van and the other 12volt on the other and simply run identical length cables to make it a 24v bank or am I asking for trouble? Searches havnt really...
