Batteries

[Peter Ball]

Hi, Being fairly new to lecky bikes, we have two Woosh Zephyr - Bs which have a 250w motor and a 36 - 10Ah battery. Should I have gone for ones with 36V - 15Am one or would this have made a huge amount of difference?

We are pensioners and intend taking them away and using them whilst on holidays with our motorhome, I've converted a trailer and fitted a bike stand to carry them.

Thanks for any advice.

Peter.

A 15Ah battery would give you 50% greater range and 50% heavier battery. Only you can say whether this would be better for you.

The 15 Ah one would give you 50% more range. Also, when the battery life starts decreasing after many charges/discharges, then 10 Ah will become a bit short in term of range.

In term of weight, the 15 Ah will be heavier than the 10 Ah one, but it shouldn't make much difference on an already very heavy ebike.

Therefore, I would go for the biggest battery possible, that you can afford.

Peter's bike is not heavy (about 21kg). The question is how much range do you need? 10AH will give you about 30 miles. Aging will lose about 2 miles per annum.

I guess you meant not heavy for an electric bike!

When he runs out of power a few miles from home, he may think he is riding a heavy bike!

Personally, I would purchase the largest battery possible, as running out of power (or worrying about it all the time) is not fun.

Hi, Thanks for the information, as you probably know the battery sits inside the frame. Eventually, would it be possible to buy a 15Ah replacement I think Woosh only do the 10? I've had a quick trawl round the internet but haven't come across any which look the same

From the Woosh Zephyr B page...

"Spare battery:

Peter, woosh will have 14AH in frame battery in August I think.

Obviously a bigger battery is preferable if you are wanting to travel greater distances but also as whilst the battery is draining, it's supplying an increasingly lower voltage and hence a lower assistance level.

For replacement cost , range and weight , I think the optimum is 11Ah . Obviously it does depend on use/route . After 6 years of riding Ebikes and 12 years of retirement and a battery re-cell , this is my opinion for what it`s worth .

12.8 Ah here (16 Ah of Lipo) that gives me about 70 km range: 15 to the station, 40 km return and a bit of safety margin to prevent range anxiety.

I think that if I had the money I would have a 17 Ah HL Li-Ion battery and nothing less. Using it a 1C would mean less sag on our steep hills.

Spare battery at under £250, for 10ah doubles your range or is a new power pack in a few years time. If the old one deteriorates.
The alternative 14ah battery will give more range or allow less human effort as you age. Enjoy the retirement until you need to replace and keep the money safe. Don't buy a new battery until you need too.
