The 12v 30amp BMS has arrived. Despite the dimensions on the site it is still smaller than I expected, which is good. 4 x 25650 3.7v 70amp Lifepo4 batteries have been ordered so the stabilising systems power supply is nearly ready.

As a reminder, this power source is needed to supply the system with a power source to stop it from shutting down when the battery is under high drain. So this 12v pack is not necessary to test the bike but needed when it is throttled throttled to full load.
