I am trying to figure out a few longevity/range issues and Lectric doesn't have great documentation on their bikes/batteries/motor readily available. My main issue stems from the fact they have the cutoff on their battery 2v higher then the display shows in settings (locked value at 40v but cuts out at 42.5) The first long ride I had this presented an issue and I had to bike 6 miles on a 75Lb bike (bike weighs 62ish with locks, saddle bags, back rack and my 185lb self (not counting the fact i was 200lb at the time, It's amazing how fast you can lose extra weight once you start biking again after 15+years) Anyway Back to the details I need help with.
I have come up with two scenarios as to why I only got 24 miles out of a fully charged 48v 14ah battery on pedal assist 2 (site claims 50 at this level and I understand weight is a factor.... but 50%?) Scenario #1.) I have a 48v nominal battery that max charges to 4.2v (per cell) and safety cuts out with each cell at 3.23 to prevent damage to the cell causing me to lose approximately 40% of the battery. Now I deem this as the "best case scenario" for the company because that means even though I'm unhappy, I will run the battery down faster and have to buy a new battery sooner (as the high end discharge of a battery cycles faster.)
Scenario #2.) I have a 50v nominal battery and am instead under charging the battery to 3.92v per cell losing ~17% on the top end and discharging it to 3v losing ~25% on the bottom for safety still losing over 40% of my battery range but instead causing the battery to last up to twice as long. This is the one I am hoping more for because this is one I can fix should I decide to completely Void warranty and upgrade with a better bms, controller and potentially display (depending on compatibility.)
Since I am fairly new in the e-bike area I am wondering if anyone on here has tinkered with the stock battery, bms, or motor to get more detailed info on exactly what is inside and if it is advisable to go ahead and start meddling with the components. I really enjoy having a working e-bike that has been filling my needs for transportation BUT the range is SEVERLY lacking on the stock battery, so any help would be appreciated. (Also I know of adding a second battery but this also voids warranty and is the other option I am looking at)
