hi to all!
i'm trying to build a DIY 18650 battery pack out of the samsung INR 3500mahs and my configuration is 23 in parallel and 30 in series = 100Ah 96V. my confusion is on charging this beast. what is a good charger that doesn't blow up the battery pack but can charge it quickly.
Any...
I have 11 100ah Thundersky cells that I would like to trade for any number of 90ah Thundersky or Winston cells. Trying to replace some week cells in a pack to keep going for a few more years. 100 ah have been kept charged and last tested at 85-90ah.
We have 32 heavily used CALB 100ah blue cells for sale. They show the following resistance:
7 - 1.2 ohm
17 - 1.3 ohm
4 - 1.4 ohm
1 - 1.5 ohm
3 - unknown
The resistance readings were taken while under load and recorded from the BMS.
These were pulled and replaced from a 700V pack.
$45/cell...
I have 48 New 100ah HiPower Lithium Iron Phosphate Cells left over from a project. I paid over $125 each for these and would like to sell them for $90 ea minimum 4 cells. I will ship same or nxt day via USPS Priority Mail for $5 each per cell, and will take returns up to 10 weeks after, as long...
