Quark 125 - cutoff settings....

[10kman]

BLipoRacer - when you say you balance your packs often, you mean while charging correct?

Aren't you supposed to balance them all the time during charging, or is it not necessary?

Sounds good with setting the voltage cutoff, I will give it a go.

Yes, when you set the cut-off voltage, you do that first, then go into programing again and select Li-Po 'normal' or 'high'.

Also, you should use at least 2.8v cut-off for lipo's minimum. I have A123's, I use 2.2 volts cut-off, A123's dump very quickly, hold there voltage right up to the last few seconds.

I either balance my packs while charging, or right after. (if after, I repeak them again.)(I dont do this EVERY time, but MOST of the time.)

2.7 is safe for individual cells, but in multi cell packs, your cells dont drain the same, so 1 cell is always lower then the rest. (especially if you dont balance out your cells, that 1 cell will get a LOT lower over time)(and then ignite)
So the better you keep your cells in check, the harder you can be on them.

The Quark has a 'soft' cutoff, it will start back up when the pack regains some juice, and I noticed that at 3.0 cutoff, the battery comes back up to over 3.2, (and still has a bit of pep to it) so I dropped down to 2.7 and now dont cutoff untill after I 'dump'

If I do catch on fire, I would fully expect there to be more spectators at my next race. :005:
