Entering it's 2nd year, and Winter, these Samsung cells are performing excellently.DrkAngel wrote: ↑Nov 05 2017 7:55pm.
... 25.9V 26.4Ah #1 finished
7s12p Samsung cells are capable of 120A continuous 240A surge but controllers are <30A and installed 40A fuse (trying new 58V fuses & holder)
Just finished 1, had to test drive it ... rain stopped for awhile.
No BMS installed! Turned out were only 20A continuous.
Mostly worried about parasitic draw when customers let set for the Winter.
10s2p Bricks disassembled into 8s2p + 2s2p and I was oh so tempted to build as 8s12p ... but needed for 24V bikes and I already have the 7s chargers.
25.9V 26.4Ah #2 nearly complete
Just need to run the parallels and power rails and install fuse.
Most markedly, #1 build maintains equality within 2/100ths V at near empty discharge.
A testament to genuine Samsung icr18650-22p!
Tested at 14ºF and still outputs good Voltage-amperage.
