EV Charger

• On Friday, learned "Eagle" ... which will allow me to design a PCB that can be emailed to a manufacturing house (Futurlec) and manfactured cheaply.
• Completed a new PCB, fitting (amazingly) into 100mm by 80mm board.

• !! BIG NEWS !!
• Plugged in the RSP-1000-48 charger, and adjusted it to 41.6V, and it charged the whole pack incredibly quickly. Amazing !
• Only problem is ... it magnified (slightly) the wrong-balance of the cells. So from 16mV unbalance, one bank now has 36mA unbalance.
• This is (of course) still quite good, but it is enough to make the "Fuel Gauge" registered unbalanced cells, making an annoying beeping for driving.
• Important, now, to get the shunt balancer working as soon as possible.
