At what voltage is a 60V battery considered undercharged?

60V battery is considered undercharged at 52V. Methods to determine undercharge: You can check through the battery charge indicator (plastic round hole style) on top of the car battery. When the liquid appears green through the indicator, it means the battery is fully charged or in good condition; when the liquid appears black, it indicates insufficient charge, reminding users to perform charging maintenance; when the liquid appears transparent or light yellow, it means the battery has very little charge left or has reached its lifespan limit. At this point, the battery can hardly be restored to normal condition through charging, and a new battery replacement is necessary. Hazards of undercharge: If a car battery remains undercharged for a long time, the most direct damage is excessive carbon buildup in the engine, leading to a significant drop in power.
For a 60V battery, I consider it undercharged when the voltage drops to around 54 volts. I've repaired many electric vehicles, especially in cold weather when batteries tend to lose power quickly. Once it falls below 54V, the vehicle struggles to start, and the lights won't turn on properly. I remember last winter, a friend's electric motorcycle kept stalling because the battery voltage had dropped to 53V. It's crucial to recharge it immediately with a charger and not wait too long, otherwise the battery will be ruined. Undercharging not only causes inconvenience but also significantly shortens battery life. I recommend regularly checking with a standard voltmeter – recharge as soon as you notice a voltage drop, or try to minimize frequent short-distance starts and stops. Generally, during normal use, a voltage between 58-60V indicates full charge, and you should be alert if it consistently stays below 54V.
