I am really interested in the ReLion LT series of batteries. These have an internal heating element for cold weather applications. My questions are: anyone have experience with ReLion batteries? What is the quality of the batteries in general? I was hoping Will would do a review on the LT...

Has anyone done any testing or experience with the Eco-Worthy LifePo4 100Ah battery? I see it for sale for $359. That is dirt cheap which intrigues on one level but concerned on another. Anyway, would appreciate any comments on this battery. Certainly wouldn't trust it for my solar system but...

I know there are several members here who know of a gentleman in Australia who has a You Tube channel, Off-Grid Garage. He built a battery, charging in with solar panels etc. I have been watching his build and just wondering what others on here think about his setup and decisions he made for...

Ok, after months of accumulating all my components for a remote cabin solar electrical system I finally not only have all the components but I now actually have my cells {280AH variety) from Amy (???). They arrived 3 days ago only 107 days after ordering them. Of course, I knew going into this...

I have been reading up on these batteries because I want to replace my AGM's at the cabin (remote cold winter location). Wil recently reviewed a BMS with a low temperature cut off that actually works which is one concern I had. (I want to build my own battery). Another concern I had was long...

A YouTuber, Freely Roaming, put together a battery that I might want to duplicate. His is using Lithium Iron Phosphate he bought from AliExpress. I was going to post the link but I get a message saying I can't post affiliate links????? So, how do I tell you all where he got them and from whom?

I have watched a ton of videos, many by Will, on Lithium Iron Phosphate and I here various individuals say something to the effect that this battery is made for xxxxxx cells. There appears to be two main types; cylindrical and prizmatic but then the reviewer assigns a number to the type of...

I have followed this guy for some time. He appears to be an engineer of some sort. He presents a case as the title indicates that for the money, lead acid is superior to Lithium Iron Phosphate. I am not expert enough to put holes in his theory so I am asking all you guys what is wrong with...

I want to find a variable resistor box that will handle high current (up to 100 amps). Here is what I want it for at the present but I will have other applications. I had a 50 amp circuit breaker installed between my Cotek 30 amp battery charger and the battery. I use the charger to...

I am looking to put up 200-300 watts of solar panels for a small remote cabin system essentially for lighting only. My question is what are your recommendations for solar panels? There are so many different brands. Not necessarily looking for the "cheapest" but am looking for quality for...

I got my EVE cells a couple weeks ago and now ready to assemble my battery in a permanent configuration so I want to use the proper torque on all connections. I did not get a spec sheet with my cells like many of you have mentioned I would. Just the cells. No paperwork of any kind in the...

Finally ordered my LifePO4 cells from Amy. Purchasing Victron smart shunt and charge controller. Still on the fence about what BMS is purchase (would entertain recommendations). Right now leaning towards Overkill. I also have an AC to DC converter/charger for those days when the solar energy...

I have been researching LifePO4/solar components for some time now. One can get overload syndrome trying to nail down charging parameters, solar components etc. so I have tried to find common threads among the mountain of information, theories and personal preferences regarding this topic. One...

Once the Overkill BMS is back in stock I will be purchasing. I know Bluetooth is included which is handy but I want an LCD display so others can read the battery parameters. The Overkill manual this can be done using a 20 x 4 LCD using Arduino. Overkill even has a Library to assist in the...

Ok, I have read a number of discussions hear on charging parameters for Lithium Iron Phosphate but none really answer my questions. Hopefully, someone can succinctly answer them. First, as I understand it, LifePO4 batteries should be charged at a constant voltage. No need for the three stage...

Here is a quote on the Victron site "In fact we can now put modules in series as well as parallel, which will also increase the input power and flexibility. Thanks to the output power or current limiter, the output power will never exceed the maximum of the controller. This Blue Solar MPPT...

I might have missed something along the way and hopefully this forum can clear it up. I am looking for a 100A BMS with documented low temp. cut off. I know Will liked the Daly but last I saw their low temp system failed during his testing. My question is; what BMS with low temp cut off is...

One of the moderators referenced this site so, being interested in charging LifePO4 batteries I checked out one of the articles listed (the one linked below). The author makes a statement that LifePO4 batteries are much easier to charge than lead acid then goes on to make a case that charging...

I had some damage done to a couple of 12v panel array. The system was very small with only 4 100W panels. I have decided to just replace them all since they are going on almost 10 years old. I watched Will's video review of the 4 most purchased panels on Amazon but that was done over a year...

Ok guys, I finally assembled my cells into a battery, equipped it with an Overkill BMS, Victron BMV-712 Smart Shunt and a Victron MPPT 100/30 charge controller and a Victron Blue Smart IP22 AC/DC charger. In the testing phase and things going very well. Have the BMS configured how I want and...

I am purchasing an Overkill BMS that Will speaks highly of and references an app one can put on your phone to monitor the workings of the BMS. I have looked high and low on his Web Site for "downloads" and I cannot find it. Anyone help me find this?

Working on putting together my off grid small solar system with LifePO4 cells (280Ah cells, 4s}. I am purchasing Victron Smart Shunt, Victron SCC and now need to decide what BMS to use. It will have to have a reliable low temp sensor since this battery will be exposed to colder temps part of...

Updating my system that has been running for 6 years. I am going to install a combiner box with a rail for circuit breakers. What brand circuit breakers have proven to be of good quality? Where can I purchase them and are they UL listed? Many thanks!

I ordered some of the 280Ah cells from Amy and although I know they come with buss bars I am very leery of the quality. Are they really 100% copper or some sort of Chinese copper alloy. I am thinking the later. Anyway, does anyone have a reliable source for good, quality tinned buss bars? I...

I have been reading on this forum and watching Off Grid Garage and, of course, Will Prowse YouTube channels among others. There seems to be no clear cut answer to my question: shunt between battery and BMS or BMS between battery and shunt? There are good reasons on both sides of this issue...

On the positive side of the Victron Lynx Power In there are fuses (Dah!) My question is a simple one but not addressed in the Victron manual of the Power In. On the middle row of studs one is to connect the Positive cables. What is the order of placement of the components to be connected...

I desperately want to convert our small off grid hunting cabin solar system from AGM to LifePO4. However, I am getting conflicting information about these batteries being STORED for months at a time in sub freezing temperatures. Yes, I know this it is not ideal to store them in cold weather...

I am putting together a very small system (4s 280Ah) for the remote cabin. I ordered the cells from Amy which should arrive next month. I have already purchased a Victron 100/30 SmartSolar charge controller, a Victron Smart shunt, 2x Victron IP22 chargers (for use when not enough sun), a JBD...
