48V 20Ah Ebike What Is Ah?

Re: 48V 20ah battery

Watt hours can be used to see how many miles pr unit of energy you can go. So a 48v 20ah battery has 960 watt hours (48 * 20 = 960). A bike going roughly 25mph unassisted will use roughly 20-25wh/mile. So if you get 20wh/mile, the bike will go 48 miles pr charge.

How much Ah does a 48V battery have?

Most battery manufacturers recommend sizing the charger at about 25% of the battery capacity (ah = amp hour capacity). Thus, a 100 ah 48 volt battery pack would take about a 25 amp 48 volt charger (or less). Larger chargers may be used to decrease charge time, but may decrease battery life.

How long will 20Ah battery last?

If a battery is rated at 20Ah capacity at 20HR, it means that the battery can discharge 1 Amp per hour over that 20 hour period . A High Rate Battery will typically be rated at 10HR or less. So if a High Rate Battery that is 20Ah capacity at a 10HR, it would be able to discharge 2 Amps per hour over a 10 hour period.

How long does a 1000w 48v battery last?

Re: 11 miles to work,what to expect out of 48v 1000w 15ah

Your commute time will be about 35-40 min .

Can I use a 60V battery on a 48v motor?

Re: How to use a 60v battery pack on 48v motor

You need to know the max voltage charge of your 60V pack to determine if it will work with your setup. What's the specs on the pack? At worst, you will need a new controller, but if max charge is 60V, then it will work fine without a problem .

What is better 24v or 48v?

If your energy needs are around 1,000 to 5,000 watts, go for a 24 volt system. If your energy needs are over 3,000 watts, go for a 48 volt system . Large off-grid houses often use 48V.

What is 48V battery?

With an integer multiple of the current 12V systems (seen in the commercial vehicle industry) 48V allows for four dependable lead-acid batteries placed in series . Thus eliminating the need for expensive batteries.

What is 48V lithium-ion battery?

48V LFeLi Battery

Lithium iron Phosphate battery (LiFePO4) has a nominal voltage of 48VDC . It is comprised by 16 cells of 3.2V each.

What is the meaning of AH in battery?

Capacity – Amp hours (Ah):

Battery capacity is measured in Ah, or Amp-hours. As the name suggests this means how many amps the battery can deliver in an hour. For example, a 12V lithium battery with a capacity of 100Ah can deliver 100A to a 12-volt device for one hour.

Is a higher Ah battery better?

As a general rule, a higher Ah battery is better for delivering more current , which implies more power in watts. A higher Ah rated car battery will generally deliver more cold cranking amps (CCA), while a deep-cycle battery can deliver medium currents for a longer period of time.

How long will a 48V 40ah battery last?

Battery is a great size and can travel for around 60 – 65 miles distance on a single charge.

How long will a 48V 13ah battery last?

Your battery provides about (48*13) 624 watts. My assumptions: On 48v motor, standard assist on my Radwagon roughly 408 watts. That means I would drain it in about 624/408 = 1.5 hrs. With a 16 mph average speed, I could go 16*1.5 = 24 miles .

How long will a 48V 100Ah battery last?

Power (W) = Current (I) × Voltage (V)

A 100Ah battery can last anywhere from 120 hours (running a 10W appliance) to 36 minutes (running a 2,000W appliance) .

How fast is a 48 volt battery?

Any car at any weight at 48 volts will go exactly 0 mph . You need current and voltage to get to power, to get a vehicle to move.

What does 10ah mean on a battery?

For example, a 36v 10ah battery pack with 360 wh of capacity. (36 volts times 10 amp hours equals 360 watt hours). This pack would in theory provide 36 km of range, or 22 miles, from a full 100% charge.

Does a higher Ah battery give more power?

In general, higher amp hours mean more runtime and higher voltage means more power.

How long will a 12v 20Ah battery last?

The simple and flawed answer is that a 12V20Ah battery will provide 120 Watts of power for an hour . If you use 35W, the battery will last over six hours.

What happens if I use a higher Amp battery?

In short, using batteries with extra energy capacity will not harm your device, but would, instead, power the device for a longer time (all other considerations unchanged).
