Hi Power Cycles says you get 27 miles on a 10AH battery?

From a Hi Power Cycles E-bay listing.


Battery: HPC LifeP04 (Lithium Iron Phosphate)

· 10ah capacity (good for approximately 27 miles)

· Most stable, robust chemistry

· Up to 2000 recharge cycles

· Built in Battery Management System for overcharge protection, reverse polarity protection, balancing functions, current limit

· Only 10 pounds

I'm new to e-bikes, but I dont think that's possible. Am I wrong?

The answer is both yes and no.

It depends on the speed your going, the amount of pedaling your doing, the grade your on, how smooth or how sharply you accelerate, your weight, a billion other things.

Range is dynamic.

If you ask them specifically, they would say 70% throttle, on flat, and no wind, with some pedaling.

My take is this is on 52V battery they have?
If so, then you have around 500Wh at your disposal. That will be 500Wh/27miles = 18.51Wh/mile which is not unreasonable. This can be achieve if you pedal moderately and keep speeds around 20-25mph. If that is the case, I would just buy a super light road bike. THough I would be travelling around 5 mph slower, I will essentially achieve the same thing without all the ebike accessories. : )

No doubt this is a stable chemistry.
You will only see 2000 cycles if you run it at 1C or less. Meaning 10A or less. If this is 52V battery, then this is effectively 500W max power consumption if you want to recharge 2K times on this battery.

· Built in Battery Management System for overcharge protection, reverse polarity protection, balancing functions, current limit

· Only 10 pounds

Sounds right to me. Might be a bit on the light side, but should right around there.

But here is my estimate if you do get that battery

~1000 Cycles if you use it normally, probably 2-3C
realistically 10-15 miles if you use it at 1KW-1.5KW
Probably 10-15lbs

Depends on the voltage, if you peddle or not and the speed.

Let say you're road legal, you peddle a little and you're at legal speed limit of 25 kph. Average should be around 8-12 wh/km or 13-20 wh/miles.

If it's a 24V battery, you'll have around 240wh capacity. So you'll use 240/27= 8.888 wh/miles. That's highly improbable.
If it's a 74V battery, you'll have around 740wh capacity. So you'll use 740/27= 27wh/miles. That's highly probable

But I think you'll be between the 2, and the seller expect you to run at legal speed, to peddle, to weight less than 70kg, cycle without wind and on completely flat road. If you peddle hard, with a 36V battery it should be possible under these conditions.

ps: And if you peddle hard enough, you can even do more than 100 miles with a 10AH battery... sellers tend to trick people like that :wink:

Guess you missed this part. And you can bet that's at 18mph.

**Range Estimates are a maximum figure based on FLAT ground, no pedaling, 170 lb. rider, 18-20 MPH steady cruise.**
