Title: PSP battery packs - caution Post by: dongle on September 24, 2006, 04:40:08 AM A couple of months ago I purchased a Logic3 battery pack designed for use on a PSP or similar. I do not have a PSP so have only just tried charging it for testing the R2. I noticed that there are many comments on the net regarding this unit - mostly negative.
The battery took about 6 hours to charge from flat using a 5.5V bench power supply. A bi-color led indicates when charging has finished and when switched to battery mode. All was ok until I measured the output voltage. Without a load it was 4.24V. I did not connect it to the R2 as this is too low for reliable operation and Ex-Navy has already established that below 4V can cause problems writing to the storage card. The Logic3 is only one of many external PSP units on the market so my advice would be to look elsewhere. However it would be useful if people could post details of devices that actually work and if possible measure the output voltage on a fully charged pack. An indication of running time would be great. This information will be invaluable and could prevent damage to the R2. |
