回答“Change battery Neato XV”Hi - The cell chemistry used for the neato pack is NiMH, six cells connected in series for a total of 7.2V per pack. The charging circuitry on the XV is built with NiMH in mind and the pack user a thermistor to regulate voltage when it nears a full charge. Long and short - do not try too use Lithium cells as they may get explodey, stick to the NiMh cells. With that said, the packs are fairly simple to construct if you have a welder and nickle strips to connect the cells or are semi decent with a soldering iron. You can repurpose the terminal connectors and thermistors in each pack to reconstruct your DIY one. Cut off the plastic casing on both packs and use one as a template as you build the second new one. I managed to pull this off but am now experiencing a software issue or possible motherboard issue so take it with a grain of salt. As long as the cells physically fit, you’re golden. Any cell 65mm by 16mm or below will fit in the housing of the XV series Neato’s. There is apparently a cap of 3200mAh in...
