I've been consistently losing bars on how much I can charge my Vectrix within the last week despite not losing pack voltage.
Yes, for example, I've ordered a USB to CAN cable, which hasn't arrived yet, to update the firmware for lithium.
A few questions:
*) Assuming my bike does not have a per-cell BMS, which it doesn't seem to, what firmware download/mods would you recommend (sans said BMS) for when my USB-to-CAN converter comes in?
*) About the losing bars (trying to figure out if this thing is still safe to drive to work)
Firstly, with the Laird firmware on a lithium powered bike, what does being stuck down to the first charger bar really mean? What will it do if that first bar dies.
I started with 12 after a charge when I bought the bike a few weeks ago.
Now I have about 5. Today when I drove back from work, I hit the dreaded first bar starting about 5 miles from home and made it home fine. However my voltmeter still said I had 143 volts of charge (this is nothing near 20% or less depletion, correct?) and after charging it has 5 bars at 146 volts (where it used to have more like 9-12 for that same voltage rating). And, even on the freeway at 60 mph, it never dipped under 140 volts.
Is this thing still safe to drive to work? Will the software cut the power dramatically if the first bar disappears, even if my voltmeter still says I'm ok?
Any other recommendations?
