August 27, 20205 yr I am selling off my battery, its time for an upgrade. This ine is still basically new and has the following usage specifications: Running off a Victron Multi 2 5000 with BMV and MPPT Deepest discharge -112.50 Ah (Was testing it conservatively.) Last discharge -75.20 Ah Average discharge -75.70 Ah Charge cycles 56.00 Full discharges 0.00 Bought from Lithium Batteries South Africa in May. Consists of 16 cells, 120Ah BMS, DC circuit breaker, wall mountable box. R20000 (Yes this is the best bang for buck lithium battery out there by far!) Same price as 4 x 200Ah Lead Acid but with loads more capacity.
August 30, 20205 yr Author Not even a comment? This is an excellent battery with double the capacity of the other brands for the price. Edited August 30, 20205 yr by Jaaks
August 30, 20205 yr I suppose what you have to take into account is that 16 LiFePO4 cells from the same source will cost R14,400 and an ANT BMS will add R2500 for a total of R16,900. At least that is what I would consider if I wanted to buy such equipment. The breaker and meter are nice to have but would already be present in an existing installation. Besides the ANT BMS provides much more useful information than the Daly BMS in your system. Hope this helps you.
August 30, 20205 yr Author OK, so you want the cost breakdown? 16 x R900 = R14400 Circuit breaker R460 BMS R2000 Connectors R450 Wires R300 Specially designed wall mount enclosure R800 Lugs, heatshrink, sundries R250 Few hours to ensure all is built correctly and works. R??? Total R 18 660 + labor, also had to drive around to all the shops to buy all the extras so add fuel to that. I added it in my head so may be out a bit. Included is the remainder of the warranty too. The source sells them for R22 200 if you can get stock. Any decent offers and we can start negotiating? If anyone can build me a battery like this with ANT BMS for R16900 I will seriously want to buy two of them!!!! Edited August 30, 20205 yr by Jaaks
August 30, 20205 yr I think people would rather buy a 3.5kW pylontechs for R20K, comes with a 10 yr warranty, works seamlessly with some inverters.. 2nd Hand batteries are still new to the market with no documented history that allows one to feel confident in the purchase... What are you upgrading to?
August 30, 20205 yr Author I want a bit more capacity so looking at larger cells. I am almost off grid with this one but must add some more panels and another kW or so in batteries. I am looking into getting 16 x 200Ah cells.
August 30, 20205 yr Hi Jaaks If you want more capacity, why not just double up on the cells and make a 16s2p battery? You can use the same BMS if your load hasn't changed. And you would need a larger enclosure, if needed. Seems the best bang for buck option? Ian
September 2, 20205 yr Just double up to get more capacity - you can also just get 50Ah cells and put in parallel if you want 200 AH
September 2, 20205 yr Author Possible yes, but I have a lead on some 200Ah cells and just need the cash. Thanks the the ideas though
October 7, 20205 yr Author Decided that is is working too well and an upgrade going to cost too much. So holding on to it, Unless I get a good offer maybe? Thanks
