I think that most fires are associated with using recycled cells and other bad building practices (see "hover boards"). I doubt that any modern commercial ebike batteries catch fire.
Because whatever caused the initial imbalance (likely higher cell resistance) will likely get progressively worse. The parallel cell group at a lower voltage when the charging stops will remain at a lower voltage (cuz no balancing).
If they are only 5 mV down with each charge cycle...
First off, batteries with quality cells charged with an OEM charger will charge at a relatively slow rate. Most cells are rated at a 1C rate. This means you could charge to 100% in one hour. But the OEM chargers charge at a very conservative rate of ~.2C (or so). So the cells do not get...
A well made battery should not be affected by shock and vibration. There is little room for movement, which causes fatigue and strain.
Having said that, I am deep into rebuilding a friend's e-bike pack that was made with nickel-plated steel interconnects.
Nickel-plated steel is well known in...
Keep your batteries inside if at all possible, especially while charging.
As for me, I am using the "Trail" power setting more often during rides instead of "Eco" to keep me from getting overheated.
I rode this morning in 95F (35C) and still climbed 1500 feet (460m) in an hour.
I have paired the Garmin (Edge 530) with the Levo's speed/cadence sensor, primarily to get the cadence data. I would like to only use the GPS to track course, distance, speed, etc. It appears once you pair the speed/cadence sensor you cannot select GPS.
I do not have a separate wheel speed...
So, let me clarify a bit. The speed readings are normal until they are not. The speed jumps to crazy fast speeds. On a recent ride, the speed went from 14.7 to 109.9MPH (109.9 seems to be some digital limit) for 15 minutes, and 2,150 miles. Then it drops back to normal speed.
1 - The native Levo speed/distance "sensor" is on the rear wheel, not the front. So on a mullet, that would be a 27.5" wheel.
2 - I have the same problem (unreliable speed/distance) with my Garmin and my Levo Gen1. Garmin told me it was caused by glitches in the GPS data. I have a manually...
