I just replaced 2 cells that where lagging behind in a customers 49
TS 260ah cell pack , and did a capacity test . I used the car for the
last 3 days and after pulling 230 ah I was not able to make the buzzer
sound even while accelerating at 300 amps ( mine BMS which controls
charger and low voltage buzzer) so I ran the heater a 30 amp load for
another hour and when buzzer sounded ( looked like about 2.7v ) I
stopped test . From most neg up . (Decimals left out )
trunk 313 309 308 297 309 311 295 321 309 311 side trunk 311 274 309
back seat 320 319 313 299 285 305 305 307 315 306 306 272 309 373
315 317 behind seat 319 269 266 315 312 301 309 312 303 310 313 324
324 313 273 309 312 323 323 319 This is probable about 400 cycles at
100 miles per cycle . This is the best performance I've seen , Hot
here in the summer , over 100 most of the time . I believe the low
amp draw when driving C2 and acceleration 2C ( with 260 ah thst's 500
amps), never discharging to far,
one extra cell to keep end of charge voltage lower than 3.6.
any thoughts ?
