July 30Jul 30 Item: Hubble AM5, plus wall mount bracket.Age: ~18 months.Price: R7500 negotiablePayment Method Accepted: EFT, Cash. (If you choose EFT, I will send you an invoice with necessary details.)Warranty: Unknown. The battery was sold to me as pre-owned in August 2025. I don't have direct contact with the previous owner.Packaging: NoneCondition: Great condition. The last BMS reported capacity was 101 ah. I have attached some recent data history from my Luxpower SNA5000 inverter, which was connected via a data cable except during times where I chose to operate based on voltage only, so that the cells can get top-balanced. If required I can provide data all the way back to August 2025, but the upload limit here was 3MB. This data will give you an indication as to what temperatures the battery was exposed to, how the cells are/were balanced or not, what the charge/discharge pattern was, etc. I'm happy to answer questions about the data. Unfortunately, the cycle count keeps getting reported as zero and I don't know why. If someone has an idea as to how I can get a real cycle count stat from the battery, that would be great!Location: Pinelands, Cape TownReason: I bought a larger single battery as a replacement, and can't pair this battery with the new battery in parallel as it is a different brand and capacity.Shipping: Not includedCollection: Pick up in Pinelands, at an address I will provide. You are welcome to come inspect the battery, before deciding to buy.Hubble-21Jun-to-29Jul.zip Edited August 2Aug 2 by dkrit Showing asking price in title
July 30Jul 30 Author I passed all the data through an AI prompt, to get a summary. Result is attached here. This was my AI prompt:This folder contains a bunch of data files.Some columns are of interest: vBat, pCharge, pDisCharge, chargeVoltRef, MaxCellVoltage, MinCellVoltage, MaxCellTemp, MinCellTempUse vBat as the battery's voltage. Tell me how much time, according to this voltage was spent in an empty / full / half-full state. Also, try infer a count for the number of times the batter was cycled.Analyze trends on the rest of the stats, and give me a general summary. Battery_Analysis_51831V0671.docx
