NeilP wrote:Maybe this is just a personal thing, but that function is more useful than the current limiting. Current limiting can be done on the board, much simpler with the pot/resistor mod. To my mind, if someone is going to the trouble,effort and expense of building the board it has to offer more than you can get with 20 minutes work and less than a couple of dollars worth of components ..I a pot and some wire to do resistor mod (S or NES series) ...

fechter wrote:I'm not sure how useful the HVC input is. It would save some stuff if it was left out.
I'm also not sure if it needs a manual restart. Normally it should not need it if the voltages are dialed in right, but could be used to 'top off' a nearly full pack.
