Hey Everyone, I have been presented with a learning experience....... I had a charger fail and I found eight (280 AH) cells puffed up a fair bit. The vents are intact. I know that cells are generally destroyed if they vent. This is a new one to me. What do you all think? Has anyone...

Hey Everyone, I am still trying to gain an education in all things BMS. I am making some progress and I really appreciate the time you all have taken to answer my questions. Regarding the control of the shore power charger: I am having a time finding a budget friendly shore charger. 8S...

Hey Everyone, I have seen a handful of places that sold new, empty battery cases to battery refurbishers. Now that I could use them, I cannot find them. Does anyone have any idea where I may find these? Thank you. S.

Hey Everyone, I was ready to pull the trigger on 8 Eve 280's instead of the FLA batteries that I had originally planned. Then I had a thought. (yes, I know, those are dangerous). My original design had my charge controller on the battery side of the LVD so that I don't blow it up by...

Hello Everyone, I am preparing for my first venture into Lifepo4. I have held on to my FLA long enough...... Rather than make my 8 x 280AH Eva's my introduction, I thought that I would order up the BMS that I intend to use and some cheap surplus Lifepo4 cells and build a small 24v pack to...

Hey Everyone, I have heard that some of the "readymade" 12v lifepo4 batteries do not perform well in a series configuration due to some issue with the BMS. Is there any truth to this? I am considering putting 4 of the following in series for my 48v battery...

Hey Everyone, I am new to the Li battery arena. I am seeing the need to be measuring voltage and current with a level of accuracy that I have not needed in many years. I no longer have a bevy of Fluke and HP gear with recent cal stickers. I am looking at my current collection of gear and it is...

Hey Everyone, I am still new to the Lifepo4 arena. I understand that, like FLA, they will last longer if your regular depth of discharge is less. A battery regularly cycled to 20% DOD on a regular basis will last more cycles than one that is regularly cycled to 60% DOD. So.... For a given...

Hello Everyone, I am still trying to wrap my head around just how the BMS functions. It appears to me that the BMS does not necessarily require that the loads and charge sources be run THROUGH the BMS. It does however need to be able to disconnect the loads and charge sources from the...

Hello Everyone, I am working on my RV solar system and had designed it using FLA batteries. I had a plan and I was sticking to it. I am shopping for batteries this morning and had Youtube playing. One of Will's videos played. Down the rabbit hole I went. Now y'all have me considering Lifepo4...

Hey Everyone, I had a midstream change of plans. I have nixed the 425A/H FLA bank in favor of a 280A/H Lifepo4 bank. I expected to be able to swap the IQ4 module on my Iota charger for the IQ-LIFEPO module. No problem....... Much to my surprise, my charger does not use the changeable module...

Hey Everyone, I have ordered 280 a/h cells from Amy. Now I have the patience of a six year old on Christmas morning. How long has sea shipping been taking for your orders? Has anyone pinned down what is the least expensive shipping method? Almost 40% of my order total was sea shipping...
