ruckus

Right.. that makes a bit more sense.. come to think about it once I get two of the same batterys I doubt I'll ever swap them out anyway. I'm having trouble decided what enclosure to buy.. very tempted to pull the trigger on the alpine tech GLX2, no idea what size lipo would if into it tho...

Absolutely, but if you decided to change from a 3S to a 4S for example.. that bridge would no longer be needed and I believe would need to be removed to safely charge.

Not sure that is wise, although this is precisely why I'm asking.. Ideally it would be great to switch between 3S/4S. If your using a 3S/4S with bridged cells, the board won't be able to balance charge correctly I believe.. it would not be receiving accurate readings. Can anyone confirm/deny ? I'm hoping we don't have to bridge any cells while using a balance connector, I think that would be the only way to switch between 3S/4S... although this is unlikely...

If we use a balance connector and use a 3S, is it still necessary to bridge T3 & T4 ?

Right, you confirmed what I assumed. I mean 0.1/0.2v's really isn't a big deal.. just wanted to make sure I wasn't missing something. Supposedly it's better long term for battery life if you don't charge all the way up to 4.20v's anyway, so I'm not really worried. Is the charge cutoff voltage something configurable ? Or is it a predetermined value ?

My DNA75C seems to struggle to hit 100% (4.20v) off the USB charger.. I calibrated the battery curve using the battery analyzer yesterday and verified the 100% node is sitting on 4.20v... * If I charge the battery's off my external charger they seem to hit 4.20v so I'm not sure why the DNA75C is struggling to be honest, the batteries are brand new iJoy 20700's... have barely been through two charge cycles yet. Is there a setting I'm missing here ? *Does the 100% node in the battery curve even determine the max charge cutoff voltage - if not what does ? I feel like I'm missing another setting determining the charge cutoff... Cheers guy's
