Hello im Ken from NW England

I wonder if someone can point me in the right direction.
I have a Revos motor and am delighted with it.
Only one problem. I can only get 18 miles out of one charge. That's with switching the motor off downhill and wind behind me.
The Revos site say I must not use any other battery or the engine will be damaged.

Is this a case of "he would say that " or would another larger battery damage the motor?

It needs to be 24v and some how a fly lead from the battery base needs adding as I believe the motor controller is inside the battery receiver base. The battery is just a two pin connection so +/- and a simple generic hook up.
I haven't bothered looking in to mine as I have two 208wh batteries and they give me approx. 50 miles range or used to before lock down.

The beauty of the Revos is the simplicity - battery, motor, sensor. It means the brains of the system (controller) is built into either the battery itself or the cradle that holds it, and I'd think that is your issue.

18 miles from a 200Wh battery is very good efficiency, and when a spare battery is light to carry, a perfect match "clip-in" solution, and only £200/200Wh, that would seem to me to be the way to go.

That's too complicated for me . I guess I will have to buy another battery.

Once I find the cells offer reduced range I shall re-cell with a better cell/greater capacity. My ones I know use Panny PF which are ok 2900mah 10a cells.
I will likely have a look at a Moly M35a or EVE 33V for a really cheap option.

Thanks for everyone's help.
Nealh, two questions if you don't mind.
1 --will higher capacity batteries give significantly more mileage?

2 ---are the batteries easy to change or do you need specialist equipment?

 

[Nealh]

1. Range will be a little better likely 15% - 20% with 3500mah cells.
2. One needs a spot welder, nickel or copper interconnecting strips and some soldering skills and a few other odds and ends of items.

For the Revos battery one is stuck with the cells Revos use and obviously the not so cheap batteries.

Using 3500mah rated cells one cna increase the std 208.8wh battery to approx. 248wh so a 20% capacity increase and a possible 15 - 20% range increase.

Currently a new 200wh Revos battery is £199 but no idea what current cells are used, I'm guessing they are still Panny PF ?

For my current pair of Revos I can re-cell them my self for the cost of £88 using Eve 3100mah 10a cells.

If I used the molicell 3500mah cell price would be double.

Another cell is the Sinowatt 30sp and would come in at the mid price of the two cells, it is supposedly a good alternative to the Sam 30Q.
