| Accelerated tests on Sanyo and GP cells |
| Below are graphs of GP 3300 cells and Sanyo 3300 cells cycled 80 times with a 2 hour |
| gap between cycles |
| Delta 0.08 |
| Charge current 4.5 amps |
| Linear charge |
| 20 amp discharge |
|
A/V1 Average voltage over first 5 minutes |
|
P/V1 Pack voltage at 5 minutes |
|
D/Cap Discharge capacity (multiply by 1000 for correct capacity) |
|
C/Cap Charge capacity (multiply by 1000 for correct capacity) |
|
D/Time Discharge time at 20 amps (multiply by 100 for correct time) |
 |

| As you can see the Sanyo pack has 2 cells ( cells 1 and 3 ) which no longer match the rest. |
| We will do further tests on Sanyo 3300 cells and see if the same thing happens. |
| The above tests should be posted by 23rd May. |
