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..

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 .

Correct they are a form of NMC I think LMO

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

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 .

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:

did you get a replacement set from them ? what was the outcome on your claim ?

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 .

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

v2 i have one left any takers ? will take a decent offer .
