What is the ampere rating for 5 batteries at 60V?
4 Answers
5 batteries at 60V is 20 amps. Detailed calculation method: Generally, 1 battery is 12 volts, so 5 batteries would be 5 multiplied by 12 equals 60 volts, with the current remaining unchanged; 4 batteries would be 48 volts; 6 batteries would be 72 volts. Charging precautions: When charging the batteries, it is important to use a matching charger. For example, a 60V battery requires a 60V charger for charging. Do not use a 48V or 72V charger, as this may damage the battery or the charger. Methods to extend battery life: Avoid storing batteries in a discharged state: A discharged state refers to when the battery is not charged promptly after use, leading to insufficient charging and reduced battery capacity. The longer the battery remains idle in a discharged state, the more severe the damage. When the battery is not in use, it should be charged once a month to extend its service life.
I found that a 60V electric vehicle battery is usually composed of five 12V batteries connected in series. The voltage adds up correctly, but you might have misunderstood the unit 'amp.' The label on the battery indicates ampere-hours (Ah), not real-time current in amperes. The Ah capacity of each battery depends on the manufacturer's label, such as the common 20Ah or 32Ah. When connected in series, the total voltage increases to 60V, but the capacity remains that of a single battery. For example, if each battery is 20Ah, the entire battery pack will still be 20Ah, which affects how far the electric vehicle can travel. When fully charged, the range is approximately 30-40 kilometers. I recommend paying attention to the Ah value when choosing a battery next time, not just the voltage, or you might end up with poor range. I've been driving an electric vehicle for three years and made the mistake of choosing the wrong capacity several times. Later, I learned to check the nameplate to avoid being misled.
I often help friends repair electric vehicles, and at 60V, it's clear that it's five 12V batteries connected in series. But when asking about 'amps,' you first need to clarify whether it's current or capacity. Typically, battery capacity is measured in ampere-hours (Ah). You should check the label on the battery, for example, if it says 20Ah, it means 20 ampere-hours. When connected in series, the voltage becomes 60V, but the Ah value remains the same, so the overall capacity stays unchanged. If the Ah isn't labeled, measuring the voltage is easy, but the capacity must be checked via the label or manual. In actual use, the current in amperes varies with the load, such as higher current during acceleration. When replacing batteries during repairs, don't mix and match randomly—ensure the Ah matches the original factory standard, otherwise, it will affect battery lifespan. Older batteries tend to lose capacity, so regular checks can prevent breakdowns on the road.
A 60V electric vehicle means five 12V batteries connected in series, but you mentioned 'amp,' I guess you're referring to ampere-hours (Ah). The Ah rating of a single battery is labeled on the side, like 20Ah or 32Ah, and the total group's Ah won't change. Installing batteries with the wrong Ah value may shorten the vehicle's range—my neighbor learned this the hard way and ended up pushing the vehicle halfway. The 60V voltage is fine, but capacity is key; checking the label is the simplest way. For safety, don't tamper with the wiring—get it professionally tested at a shop.
