    Can I use a 10S Li-ion BMS for 8S LifePo4 DIY build?

    Thanks for the response and insight. I ordered two new JBD 8s for LifePo4 from SRIKO battery yesterday since I need them quick. I am curious - is the limitation to use the 10S Li-ion in the settings/parameters or the hardware itself of the BMS? I would think you could change the settings to...

    Can I use a 10S Li-ion BMS for 8S LifePo4 DIY build?

    A while ago I ordered (2) JBD BMS's. I thought I was ordering 8S LifePo4 Smart BMS. Instead I ordered 10S Li-ion Smart BMS. Can I use the 10S on the 8S LifePo4? I would think I would be able to modify settings to work for LifePo4, but not 100% sure. Anybody have any idea? Also - not sure...

    18650 Battery Store Legit? Will not answer the phone.

    I didn't listen to the whole recording. I do find it interesting that the call lasts 30+ minutes and yet I still can't get the excel information about the 304 cells I ordered and paid for. This would suggest that it isn't a matter or time/manpower for customer support but instead that they...

    Need more energy - Multiplus in 3-Phase or Parallel Split-Phase?

    Seems like when I add more capability, I find more and more uses for my energy. I have 24V system with (2) Victron Multiplus 24/3000/70 set up in Split-Phase Configuration. I decided to do Split-Phase as opposed to parallel configuration because with split-phase I didn't need to balance my...

    Here are the reports I received - attached to this. I know reports can be fabricated - sounds like we could double check with Eve - that would be bad for reputable vendor to be found out fabricating. I will probably just assemble cells and see how they work. Nevertheless, if I had the reports...

    18650 Battery Store Legit? Will not answer the phone.

    So after posting here in the forum, I received 50 pages of battery reports from 18650, but none of my batteries are listed in these reports they sent me. So after waiting over a week, they finally got back to me, but didn't send the correct reports. I am sure they know what cells they sent...

    18650 Battery Store Legit? Will not answer the phone.

    Not sure if co-incidence or not, but last night I received 50 pages of excel battery reports from 18650 - it will take a little time to look at data for batteries I received...

    18650 Battery Store Legit? Will not answer the phone.

    I hear what you and Tim are saying - I have bought B cells from Ali in the past and I had the same attitude. But I don't think everything else is irrelevant for everyone. I think if I had the reports, I could use them to build more matched 24v batteries and squeak out more storage. I also...

    18650 Battery Store Legit? Will not answer the phone.

    I want the reports so I can better sort the cells for my (2) 8s packs. If I ever want to sell these, having the reports would increase the value. I find it very disappointing they aren't following up on what they advertise - it makes you wonder what they would do if there was damaged cells or...

    I ordered some Eve 304 cells from 18650. They took my money and I got the cells quickly and they arrived in good condition. I have requested the excel reports for these cells three times and they have never responded in any way even though they advertise that these reports are available...

    Source for predicting cloud cover?

    I must not have communicated very well. I have a couple years of wood cut and split and covered in reserve. When I burn this, I need to replenish it. Maybe you have to experience heating with wood to know what is involved. Without electric heat, I need to basically have a fire going from...

    Source for predicting cloud cover?

    I am in Wisconsin and off-grid and my only other heating source besides solar electric is a wood stove. So, my return on investment for watching the weather and using my batteries to heat with is less firewood to cut, stack, store, split, haul inside, and fuss with every few hours (and have my...

    Source for predicting cloud cover?

    Needing accurate forecasts is crucial for me. I have plenty of solar/battery for critical loads, but want to use my batteries as much as possible for electric winter heat and forecasts play a key role in this. I will check out Solcast - thank you for link...

    Victron Charge Controller Price Crash

    Well, I would argue that while there are two different camps, people are not locked into one or the other. For everything there is a season... For much of my life, I valued low cost over other attributes - and I was willing to put up with aggravation and cobbling, etc. I am on my third...

    Do You Ever Regret Going Off Grid?

    If you are at the right latitude the no-power fridge is awesome. I am colder here in winter and often have my chest freezer in shed and running heating pad inside to bring up to fridge temps....a converted chest freezer was my original solar system refrigeration - its so efficient. I still use...
