  • Post in thread: Using excess solar to heat house

    Wow, is what I say after reading this thread, but I agree with you 100%. You know what you need and how much solar production you are getting, so no need for any reason not to do it. I'm in the same boat, here in Canada Ontario, we get the best solar production starting in mid January, when it...

  • Post in thread: Senbury LiFepo4 cells 280ah

    This is a picture taken just about 17 minutes later with a load of 600 watts only. You can see my point that cell #16 is now the lowest, and if I apply a good load it would go down really fast to maybe .050 v lower than the rest.
  • Post in thread: Just Place new Order on Alibaba- 280AH x 8 for 1260.00 USD Delivered, Grade A to Canada

    Received my batteries this morning, everything checks out good, no damages well packed, ordered and paid February 18, 2020, received April 30th. Batteries test all 3.2929, missing the screws apparently that was my gift as Amy said. Now I have to find the right bolts for them. M6 bolts, most...
  • Post in thread: Just Place new Order on Alibaba- 280AH x 8 for 1260.00 USD Delivered, Grade A to Canada

    I'm in Canada Ontario, stores are open but only online orders, so I have to make sure it fits. Edit: I rechecked my boxes and I found them in between the layers of foam between the two cardboard. ?
  • Post in thread: Has anyone purchased/tested the lifepo4 310ah from aliexpress yet ?

    I see you took a leap of faith on these 310ah from Exliporc new energy, this is a good supplier, Gina Zhang is the owner and been in the battery business for 10 years. I've ordered 32 of them and I just received my tracking numbers from UPS. Here's some specs from the supplier, where she...

    There is a few utube vedeo on the subject, if you look in there, you will find, I did a while back, I've ordered 24 supercapicator 2.85v 3400f 2 months ago and I'm still waiting for them. I will be installing them with two new banks of lfp, also ordered. It will save your batteries and good for...
  • Post in thread: New BMS from IC GOGOGO Store / E&J Technology Group

    Nice to see in action, in your picture above you can note power is being drained from 01cell and being dump in #15 cell, to balance them. So it shouldn't take too long to balance the pack.?
  • Post in thread: Has anyone purchased/tested the lifepo4 310ah from aliexpress yet ?

    Mine is Canadian $ all in DDP. yours cost close to 6000$ for 32 and unsure of quality grade. 185.375 each cd
  • Post in thread: Has anyone purchased/tested the lifepo4 310ah from aliexpress yet ?

    Hey nice to here good results, to me these cells are as much grade A cells than any others found here on the forum. In the posting or site that you purchased these, in the specs they are advertised as nominal capacity of 300ah - 310ah. Just saying these looks great, no complaints here.
  • Post in thread: Xuba Electronics: DEAL - 280AH LiFePo4 cells. Purchase & Review

    I bought 32 cells from Xuba delivered to Canada shipped by sea CIF, it took ~68 days, they shipped to Vancouver, had inspection of container, which added 67$ to the cost and delayed 2 weeks, then it travelled by train 3,000 km to Montreal. Then you pay broker fee, which was good ~188$, then...
  • Post in thread: Parallel Supercapacitors with LFP bank

    Yes sump is small, I prefer to have the water evacuated before it becomes even with the weeping tile. These are all 16 v 500 farad banks with balancing circuit on each two capacitors, I used 4 bank minus 2 capacitor, hook up in serries to give me 59.4 v. My batteries top voltage is 56.8 v so I...
  • Post in thread: REPT 280AH Cells from Exliporc - Making 48v 560AH Battery

    Surely not grade A as advertised, and not as honest as I thought they were, but after six months from my first order with them , I did receive a small compensation of 6$ per cell for them giving me false information . The cells I’m referring to were CATL 310ah advertised, tested 285 to 293 ah...
  • Post in thread: New BMS from IC GOGOGO Store / E&J Technology Group

    Look at earlier post, #78, and before for pictures and explaination. Like I mentioned I followed the bms reaction all the time it was hooked up. Lasted 14 hours. I monitored the batteries individually manually. Right now my batteries are fully controlled with the inverter and charge controller...
  • Post in thread: Senbury LiFepo4 cells 280ah

    I have two banks of 16 cells parallel 280ah without a bms, but I did add an active balancer on each bank that I can monitor with my phone. Since adding the balancer I've noticed that not all cells are equal in some form or another. Capacity, resistance and chemical reactions within are not all...
  • Post in thread: Buying from Alibaba

    I bought all my solar system from Rob, I'm two km from the store, sea freight is not all that bad, you hire a broker on line and they custom clear your shipment and could even arrange for delivery to your door. I should save 500$-1000$. On the order of 32 cells like yours. The only problem I...
  • Post in thread: Shenzen EFire BMS, anyone?

    I called it a relay, it is the contact Mechanical used in your BMS to provide source connection to the load. As in the pictures.
  • Post in thread: Magnum Energy MS4448PAE LiFePO4 Charger Settings:

  • Post in thread: Using excess solar to heat house

    Around that time of the year, the sun is really bright and the sky is very clear and clean, and it seems that with the coldest days the rays are strong, please note I said it starts mid January to have better solar charging. So it climbs up eventually more and more every day when it's sunny,of...
  • Post in thread: Energus Tiny BMS

    I have the same setup 2 parallel battery bank, you need one bms per bank, or you can parallel 2p x 16 then series into one bank and use one bms. I've been searching for a bms and this one made My list. I'm presently running without a bms, and I'm debating between the batrium which is my...

  • Post in thread: Xuba Electronics: DEAL - 280AH LiFePo4 cells. Purchase & Review

    I ordered 32 batteries shipping by sea to Montreal port. Apparently Amy told me they were sent to the logistic today.
  • Post in thread: New BMS from IC GOGOGO Store / E&J Technology Group

    This is not a chargery. E&J technology. I ordered 2 of them, active balance compared to passive balance for the chargery. It is best for you to do your research, it is well documented and the manual is in details also. http://mysharegadget.com/943450729
  • Post in thread: XUBA 280ah in 48v w/ "dumb" inverter/charger

    I have two banks of cells in parallel 16s2p, burnt two bms on the first day of use, I have top balanced every cell individually, with a drok dc-dc buck converter 10-75v input to 0-60 v output 0-12amps, and I have been using them without any bms for 90 days now and all my cells stays balanced up...

  • Post in thread: Bottom balance then no BMS

    I've been running my system without a bms for a 11/2 day now and I monitor manually and it seems ok. I had two Bms16 installed on my first day and they quit 14 hours after. So as long that the inverter can control your voltage, I believe it should be fine. These are new 280ah cells and a newer...
  • Post in thread: Just ordered a new to market BMS

    The red and black wire plug is for an external switch to power it off, or on. I've not used that option.
  • Post in thread: Classic 400 Watt Solar System w/ minisplit

    I have a 12000 btu senville, on solar power, and it takes 1000 watts to get started and running until it reaches its temperature setting and then it will drop to about 600 watts to maintain you're temperature. This is for heating or cooling. This is also for the 21+ seer rating.
