Could I damage my Voltbike battery if I don’t charge it for long term?

Yes, leaving your battery uncharged for a long period can potentially damage it, especially if it's a lithium-ion (Li-ion) battery, which is commonly used in e-bikes. Here's why:

1. Deep Discharge:

• Li-ion batteries have a built-in battery management system (BMS) that prevents them from discharging completely. However, if the battery is left uncharged for an extended period, it can eventually reach a critically low voltage, causing the battery to enter a state where it can no longer be charged or used properly. This is often referred to as "deep discharge," which can lead to permanent capacity loss or failure of the battery.
• Most Li-ion batteries have a low voltage cutoff (around 2.5V to 3.0V per cell). If the battery falls below this level and stays there too long, it can suffer irreversible damage.

2. Self-Discharge:

• Even when not in use, Li-ion batteries naturally lose charge over time due to internal chemical reactions. However, the discharge rate is slow. If the battery is left for months without charging, it could discharge to a level where the battery's protection circuit kicks in and prevents charging. In some cases, if the battery reaches a very low charge and is left in that state for too long, it can affect the overall battery health.

3. Battery Degradation:

• Extended periods of inactivity without charge can cause chemical imbalances inside the battery, which will lead to a loss of capacity, reduced efficiency, or, in some cases, complete failure of the battery. This is a gradual process that may not be immediately apparent but will impact the battery's lifespan in the long run.
