Had a quick wee test at work today, but me being me, I forgot to take my camera. Wasn't a whole lot to film though; it was a wooden cabinet it was up against but it was quite mouldy/damp so instead of bits flying off everywhere, there was mostly just lots of sawdust. But my colleagues seemed suitably impressed.
The drum had about four spin-ups during the test and was running for about three minutes, but by then the drum wasn't reaching its full rpm and you could hear it running down. The battery was setting off the low-voltage alarm by the end of it, so suspicions about the battery capacity have proven to be an area that needs addressing.
Two options: the first one is that I need to beat all my opponents within a minute or two![]()
The second, more feasible, option is to connect two packs in parallel. Going to a single bigger capacity pack is fine in theory, but there isn't enough space as the packs get bigger as the capacity increases. But I'd bought a second 18.5V 2200mAh pack to act as a spare, and there's enough space to fit it on top of the existing pack (provided that doesn't cause any safety issues and that parallel connection of lipo packs is fine) so sorting that out will be a job for the weekend.
But that aside, the test showed no major problems. Drive was fine and drum was fine; probably the first test I've ever done that has ended as a result of low batteries rather than something coming loose and/or breaking![]()
