The problem:
When connecting LiPo cells in parralel, massive equalisation currents can flow, especially if the voltage differs significantly. https://www.rcgroups.com/forums/showthread.php?2297114-Equalizing-two-LiPo-s
It's been a bit of a 'pain' to charge 16 packs to the same voltage. Once I got to the 16th pack, the 1st one was out of whack again.

The solution:
Instead of using resistors, I've come up with a different idea, using diodes.
The diodes will stop the cells discharging into each other, but will allow charge to in from the charger. There will a slight voltage drop from the diodes, but I can turn the power supply up to match the drop in voltage. To compensate from the drop in voltage, I have ordered Shottky diodes, which should have a lower drop across them.
I'll let you know how it goes. There have been several suggestions that diodes are not very reliable, and might fail-shorted. If they do, they will most likely burn out, like a fuse.
