Gregory's Serverwith the fuses welded in place, i've made a new insulator to cover their tabs and prevent them from shorting with the main battery negative terminal strip.

it's all reassembled now in the enclosure. the plastic strip holding the gold-plated terminals slots into the front of the case. the schematic of the pack looks like this. it's two series strings of cells connected in parallel. the fuses prevent excess current from flowing. aaaaand it didn't work! no life at all. why? the battery terminals inside the Thinkpad 700C are corroded! these should clean right up. |
i've unfolded the cells now so they lay flat. i have to weld the two positive terminals (on the red wire, somewhat out of focus). the other little thing hanging free is the thermistor.
