Rebuilding an Ebike Battery

ebike-batteryA few of our members and visitors use Ebikes. We were presented with an Ebike battery which had a dead cell. The plan was to replace the cell with a new one. This is not ideal, since you end up with a mix of old and new cells, but the balance circuit should make it usable. On further investigation we found that there were a number of dead cells. So we set about rebuilding the whole battery with new 10Ah cells.

The cells are 10Ah LiFePO4 type…. 12 of them in all. The new ones are a little bigger than the old ones, so we will have to modify the case a bit, but that won’t be a show stopper. Drop in during our fortnightly electronics night to see the build in action.
