Might go without the BMS

DIY Electric Car

Despite the cost of the thing, my experience of two small shorts while wiring up the pack - 7.2v only - has scared me sufficiently that I don''t want any unfused cabling where it could possibly short out the pack. At the same time, fusing 100 cells would take days and my usage is likely to be only 30% of real pack capacity, so I can probably stay away from both ends. Anybody want to buy an unused BMS

Cleaning aluminium oxide off terminals

DIY Electric Car

Wiring up the pack. After doing 70% of it, I read on evworks that it''s a good idea to clean the terminals with a wire brush to remove aluminium oxide. So disconnected all the cells and BMS cabling. A whole day "wasted" - except that it will hopefully perform better with the lower resistance. I was surprised at the change in colour/albedo on some of the terminals, I''d never noticed they were oxidised
