  1. If your Discharge current limit drops to 0A you effectively cant draw anything from the battery as this is what the BMS is telling the Inverter it can and cant do . Discharge current limit should only ever be effected when the battery SOC falls below 15% .. Prevents High discharge from taking place on an empty battery ( cells at low soc can fall off the discharge curve easily ) It doesnt drop to 0A until the battery is empty at 0-5% SOC . So this is weird for a battery with a 97% SOC..
  2. strange the bms has two sets of mosfets one for charge and the other for discharge the fact that its switching off both tells us its a major error .. it could just be a balance issue ...but do a discharge test see if it rates to full capacity and then charge up but use manual voltage instead when charging ..use 55.2 volts bulk/float slightly less for the test and see if it does the same thing .
  3. Please Send me a Dm with your number will Contact you on whatsapp and guide you. P.s Compliments of the season .
  4. Dimensions . Details for cells . cell make and model = AESC 32.5Ah Cathode = LiMn2O4 with LiNiO2 Anode = Graphite 290 x 216 x 7.1mm weight = 0.787kg We have 188 cells remaining . 34.*Kwh of energy storage . Price per module 100 Rand each ! Price Drop.
  5. Bump open to reasonable offers ! please Send PM
  6. Correct they are a form of NMC I think LMO
  7. P.s a member suggested i write up the following 1 Module has 2 cells in series . 3.7v + 3.7v total 7.4 volts With a cell tap in the middle on the cell module for monitoring each cell with a bms . 1 module is 3.7v x 2 and 25ah = 185whrs . Normally built into a 14s3p arrangement for 48v would mean a 7.7Kwh battery for R5040
  8. The Guys over at Custom Lithium are building replacement packs for these Nissan leafs 40Kwh with 300kms +, given the average cycle life of NMC cells that would yield a life span of 600 000kms to 80% (2000 cycles with each cycle giving 300kms ) Lets work on worst case that would mean less than half the life span for our climate and or our current conditions ( say the battery only gave 1000 cycles ) thats still 300 000kms to 80% remaining capacity . Not bad i think .
  9. For Sale Template Item: Nissan leaf Modules in 2s (7.4v) Age: about 35% soh on the low end and 50% soh on the high end Price: each module 120 ZAR Payment Method Accepted: Cash/EFT Warranty: None Packaging: in their original casing Condition: good working order Location: JHB Reason: replaced a few batteries for clients Shipping: at buyers expense yes Collection: yes by all means i need space Link:
  10. did you get a replacement set from them ? what was the outcome on your claim ?
  11. 73kwh in total 96cells packed in a 8 x 2 arrangement the modules are large and heavy 6 of them from a low mileage car . Each module has 16 cells .Vehicle had done 320kms . Will come with harness assemblies to tap into the cells . Price for the total lot is 130k Zar . Will come with bus bars as well. nice for an energy storage project or Ev conversion .
  12. Selling 73Kwh of ev cells Comes in 6 Modules from a low mileage vehicle ( cells are CATL) Total of 96 cells packed into Modules (6) that are 8s x 2 (16s when strung together) Comes with cell harness and some bus bars . Vehicle had covered 350Kms . Price is 130K ZAR incl vat
  13. v2 i have one left any takers ? will take a decent offer .
  14. Send me a pm i have a nissan leaf complete motor with inverter and charger for sale that would work . Pretty straight forward . We also have a 70kwh battery in stock that would mate to it comfortably
  15. eermm what happened ?
  16. P.s Great for Ev conversion or very light weight battery for mobile applications . If setup correctly they are by far the most energy dense . Lifepo4 5Kwh = 45 Kg 2 x modules in 5Kwh = 24 Kg big difference . lots of high voltage powerwalls being made in First world countries using EV batteries too ... gaining lots of traction .
  17. Indeed like any lithium chemistry if you dont look after them they wont look after you . These are Prismatic cells for reference ..
  18. They are 6s config so 22.2v some modules do have a Board installed roughly 50% have pass through cables and the other have pcb boards installed . The module is super light coming in at 12Kg . so thats almost 5Kwh for 24Kg weight .
  19. Item: VDA 355 Modules for sale from a low mileage EV each module has 6 cells in series they conform to the VDA 355 standard great for Ev conversions of classic cars or energy storage . Each module is 2.47Kwh with a 6c discharge for 5-10 seconds and sustained 300amp discharge . We also have contactors and connector harnesses available and each module will come with a plug and pigtail Age: Low mileage 20 000kms or less Price: 5800 Rand each Module of 6 cells Payment Method Accepted: CASH/EFT Warranty: Each module will be verified with voltage Packaging: None they are packaged already Condition: Used and removed from the battery housing Location: Johannesburg Reason: We got lots of stock Shipping: at your expense Collection: Johannesburg Link:
  20. We have stock of VDA Modules available if any one needs for an electric vehicle conversion please send me a DM price is 5800 Rand inc Vat . They can handle 300amps for 20 seconds and 600amps for 10 seconds. come with wiring harness . Came out of a vehicle with 30 000kms . Cells are CATL with aluminium casing and plastic lid that can be removed . Some have the BMS Board attached some dont . The bms units have a LTC chipset for 18 cells but of course each bms will be wired into 12 cells . BMU and contactor box can be arranged for those wishing to build the full battery which is 18 Modules (44Kwh )
  21. Cells are still in the complete pack sitting on a pallet outside .. they are from the generation 2013/4 model of nissan leaf
  22. They come as cells only no bms on a nissan leaf battery no way of knowing how many cycles its done i cant offer that information . I can only offer leaf spy shots showing the SOC and SOH of the batteries in their complete state.
