I have a trampa, with a 12s lipo battery (2 x 6s in series), 6000mAh. So at full charge the battery is at 50.4 volts (4.2 per cell). Low cut off is set at 42 (3.5 per cell).
I have a bunch of 1s batteries. Does it make sense to put a 1s battery is series when the battery is at 46 volts (3.8v per cel) ??? So it will be switching to a 13s battery and voltage back to 50 volts?
I plan on using a 1s2p battery (2 x 5000 mAh in parallel.), 10,000mAh total, not too much additional weight.
If I do this the total voltage will be back to 50 volts, and less battery sag??? Does this make sense???
The idea is that by just adding only a small 1s2p battery when the main battery is getting close to the low voltage cutoff, switching to a 13s will reduce battery sag.
I have an alarm in the main 12s to detect when any cell is below 3.5 volts.
