Common Questions about A- Grade Answered
- Actual Capacity when new is approx 321-333Ah – The supplied excel spreadsheet always says 330-339ah, but this is 90% of the time never true.
- Usually they are ~320-328Ah
- The IR for the MB31 model only is usually above 0.18mΩ for the MB31 cell
- The best way to explain what Alibaba sourced cells are, especially if under the EVE factory price,
a) If 100,000 cells are made, these are from the bottom 20%, with B grade likely from the bottom few %.
b) They are not B grade, which are significantly problematic, and should be avoided if you want a long life battery pack with no failing cells. - Cycle life is likely affected significantly with A- Grade, when A grade might reach well into the decade territory, A- Grade might see problems arising much earlier.
- They are more suited to DIY battery builders who have the ability to repair their battery packs, without major cost and expense.
