I received my EVE cells, 7 cells at 3.30 v 1 cell at 3.29 v 1 cell had a deep dimple damage, I contacted Xuba, no response yet. I am going to tape the cells in a 4s1p config, What can I use as insulator in between the cells? I have some thin cutting boards from the dollar store, but what...

Greetings from sunny/balmy West Michigan! I bought 16 of the BatteryHookup 6000mAH, 32650 LiFePO4 cells. These are BRAND NEW cells per their ad. I took the voltage and they are in the following range: 2.90 to 3.30 range Questions: 1. Is this expected of NEW cells? 2. Does this mean their...

I see Daly says they can customize their BMS. I am looking at their WATERPROOF LiFePO4 BMSs. I want lower max volts and higher cut off volts. I know I can do this with the SMART BMS but I need a waterproof BMS. Can Daly customize their voltages for their BMS? How would one go about enquiring...

I am just getting into Li batts and my el cheapo meters are lying to me. I read that some volt meters are more accurate than others. What is an accurate volt meter on amazon or ali? How does one use a voltage reference module?

Anderson connectors look to be popular, I have seen on the video reviews of popular all in ones and lithium batts with Anderson Connectors. SB 50 and SB 120 Any one ever find bulk packs of these?

https://jag35.com/collections/new-arrivals/products/20-cell-pack-eve-icr18650-26v-3-6v-2-55ah-7-65a This pack is from the scooter handle bar stem, Does this have a built in BMS? Can I wake this up? I hate to take it apart, it would be nice to use it as is. I looked on the interweb and could...

A123 36V ANR26650M1-B LIFEPO4 I bought one of these [batteryhookup]. This was a used unit and it came in with 39.5 volts [yeah] This was used as a backup battery for Dell EMC rack unit [from my googling] From what I found on ebay, these were inserted into battery bays. The BMS turns off...

Greetings, 24v Inverter - any out there with a wide Voltage range, say up to 42 volts?

I bought one of those 48v LFE batteries with dead cells from BH, I need to cycle the battery but I don't have any 48v inverter. Could I use a regular 110v 100w table lamp with an old style incandescent bulb to discharge it?

I am totally amazed to see 10 plus year old batteries being sold online with little or NO info as when they were made or put in service. Some reputable sellers put a guesstimate on year the batteries were made. But major sellers skip this very important information. Surely they know the...

Daly 24v or 48v BMS at around 100A, 1. Fan stays on all the time or just turns on when needed? 2. Fan serviceable? 3. How loud is this fan? 4. Where is the air intake? I am guessing the FAN version is preferred for staying cool aka cool factor and longevity. Would a large heat link on top of...

What connections is used by: 1. Daly BMS? 2. Cellmeter capacity module 3. ISDT BG-8S Are there adapters to connect a BMS wire to a ISDT-8S?

48v - I am digging it for my solar solution, I am looking at 48v components. First was LIFEPO4 prismatic cells. 280ah - is just too big, too much space needed for my little tiny ranch. I already have 4 littokala 100ah prismatic cells, so I went on Aliexpress to look for what they have and I...

Good Monday Morning from West Michigan, Grandma and I are planning on hitting the piers for some spring fishing, I bought an old (2013) sienna awd to fish. I want to run a 300w small heater in the van for heat. The setup will be simple Heater > Bluetti Bluetti Solar input > 36/48v...

I need a 3.7v to 12 boost converter, preferably the sealed waterproof enclosures. Any one find one?

A/C connector, looks like a molex of some sort, any idea what is this? [Mole, molee, molo - Austin Powers]

Good Monday Morning, I ordered 1 each of the following 12V battery packs from Batteryhookup https://batteryhookup.com/products/12v-lifepo4-a123-module-w-bms The Battery I received was FLAT, 0 volts.. I emailed them to get a replacement, crickets till now unfortunately. Q: What is the proper...

I see BT24 meter are bidirectional, but this one needs an external PS What are the options for a bidirectional Amp Hour Meter that will keep the number in memory if disconnected?

Good Morning, Anyone have any experience with EATON - Cooper Bussmann Pure Sine Inverters? These are supposedly used in Semis and Ambulances and there are supposed to be a bunch in use out there. Anyone care to comment to the build/internal design, are they really robust...

All I can say is OUCH! I bought the r7 ebike battery cuz it came in a "cute" downtube enclosure. It is rated at 9ah at 36v. Batteries were heaters, I charged them in stages and let them sit, charged them again.... fully charged them and then connected them to my capacity meter, walked away...

Saw this battery, nice case, any clue where I can get one? I love the nice clean shiny look!

Good Morning, I bought a few of these dead motorcycle batteries off BH. I want to TRY to reuse the plastic cases. How do I go about attempting to open the top with the least amount of damage? It seems they have some sort of glue applied. Heat?

I bought a 48v battery made of 27ah prismatic LIFEPO4 cells, I opened up the metal case and this sucker is stinky, pungent. I looked for leaks and I don't see any. I have a bunch of other prismatic cells and none of them are stinky. what gives?

I was peeking at some battery porn at BH ;-) BH has this Samsung 48 volt module that uses a 15s BMS but has only 13s hooked up, 1. BMS design allows this? 2. BH mentioned higher cut off voltage due to the fact 13s leads are hooked up on a 15s BMS 3. Do a BMS actually see the total voltage? Or...

Michigan started new PEAK hour rate for summer months. Which all-in-one do you recommend for: 1. Peak time - help the GRID with both SOLAR and BATT, so I need the timed UPS feature 2. Need to able to set priority to GRID > Batt etc : Timed, I need to able to set priority to batt during peak...

Blocking diodes. 1. Meanwell and other power sources, boost converters - good practice to use a blocking diode to prevent current back flow. 2. Solar panels have the same to prevent batteries from being drained when the sun don't shine :) This thread is to collect the Off the Shelf products...
