Connectors on hi power battery pack
Posted: Sat Mar 14, 2009 6:05 pm
Two simple questions really:
1. Looking at the connectors delivered with my Hi Power batteries (look like 1mm steel) I see two problems: wrong material, way to flimsy. I've calculated that I need 50mm2 (copper) cable to connect battery pack to controller (100A cruise, 150A peak) so a 20mm wide aluminium (60% of conductivity cf. copper) connector would be equivalent if it was 50 / 20 / 0.6 = 4mm thick. Sound right? Anybody else used similar or has other advice?
2. Replacing the bolts: the fasteners will be too short, so I need a UK online source for these - M6/1 - anyone know where to get aluminum threaded bar? or alternatively is passivated steel OK? I tried RS but too long.
(Sorry I searched for "connector" but didn't find anything on this.)
