100 mW
I am trying to work out why my 12s3p (48V 15000mAh) lipo pack is giving me such poor mileage. I am only able to achieve 17kms (10.2 miles) riding WOT (1KW conhismotor, max speed 48km/hr) before I reach 41.5 v LVC on my controller. This is slighly less than when I was running new packs with 12s2p (48V 10000mAh). I have charged them approximately 250 cycles. I have also accidentally mixed some turnigy and zippy packs together in my battery config. I parallel charge my 6s lipo packs on a parallel charging board and use a TURNIGY MEGA 400W V2 Lithium Polymer Battery Charger.
This problem seems to coincide when I fitted a larger 400w power supply for the charger. I then increased the charging current up to 17amp to reduce charging times. I have since now reduced this to 12amp but no improvement with mileage.
Is it possible that my Turnigy charger could be charging my packs up to the correct voltage (25.2 V) but not charging the cells to full capacity (mAh). So instead of having 15000mAh available, perhaps I have less.
Is my problem due to the fact that I charge my cells in lipo mode 4.2V/cell instead of charging in lilo mode 4.1V/cell, and now the batteries are worn?
Is this reduction in battery life typical for running 250 cycles?
help please :?
