batteries

[gray198]

does anyone know if it would be possible to use a 10ah 36v battery from a juicy bike on my freego Eagle. Just thinking that if I wanted to go for a longer ride I could carry the battery from my wifes Juicy folder in panniers to give an extra 20 to 30 miles range. I have had a look at the connectors for both and they seem to be the same, but will there be any other compatibility issues regarding the motor or controller etc.

Thanks gray

As I am not familiar with either of these bikes, I can only give a general answer. I assume that the 2 batteries are of the same nominal voltage. Only two wires are needed to connect a battery to a controller. However, some manufacturers us plugs/sockets having more than 2 pins, as these are cheaper. If this is the case here, you need to find out which pins are used and which are spare. If the same two pins are used on both batteries, then the only thing you need to worry about is polarity. In other words, is the positive connector on the same pin on each battery, and likewise the negative pole. A multimeter will answer this question, but only if you know how to use it . Get it wrong and you will fry the controller. Need more info? Just ask.
Incidentally, if the batteries are of different Amp/Hour capacities, your "fuel gauge" will not be accurate when used with a different battery.

Additional to Neptunes reply above.

Lay the two batteries side by side and view the bottom caps. The polarity is clearly marked on them. All you need to do is make sure the sockets occupy the same position on the caps...some are slightly offset. I don't think there will be a problem, as Juicy and Freego bikes are made in the same factory.

I used a Juicy battery to replace the original Phylion fitted to my Spanish Tucano Carrera. The bottom contacts and charging port were identical.

thanks guys
i'll have a look and let you know how I go

well both batteries are identical in all respects except that the freego is 16ah so about 4/5in longer. So the smaller battery will not slide down the retaining rail to reach the contacts.. There is a lug on the battery that stops it and also a locking pin. I think a new hole could be drilled for the pin but at this stage not sure how to overcome the lug.

Before making the connection, check both batterie with a voltmeter to see that the polarity is the same. You can't go by any markings. If the polarity is wrong, you'll melt your controller.

thanks m8 will do that

You could try moving the locking strip from the FreeGo to The Juicy. Then the taller battery would lock into the Juicy. However, the taller battery, when placed into the shorter strip (Now the FreeGo) would not engage the lock.
You will need to make a new fixing hole to fix the strip to the frame.
You would of course void your warranty by mixing the batteries between the bikes, but as it's Freego, we have no problems with that and would still honour our warranty. We know them well and they are fellow BEBA members.
Hope that helps.

How would suppliers know if a customer was mixing or using different (compatible) batteries between bikes ?

Is the electric different in each battery ?

Sorry it is Friday

Jerry, to be frank, we wouldn't. Each battery is uniquely numbered, as are motors and frames, so those can be tracked. But what each customer then does with their goods is up to them, hopefully using the batteries (etc) appropriately and for the purpose intended.
Taking a battery designed for one of our bikes, and using it, say, in one of Fred's bikes, may overload it. In this case though, I am well aware that FreeGo share a very similar spec and I am happy that our battery would not be compromised.

 

[jerrysimon]

Yes good point. I guess I had overlooked that for some ebikes, though usually cheaper ones, the C rate would be different/lower and lead to damage if used on a more powerful setup.

Thanks for all replys
@Bob Juicy Bikes, thanks for your positive response and helpful comments. Now i know what is possible, but don't think I am going to start messing about changing things.
Another thought, would it be possible to get a case identical to the 16ah battery and build a smaller capacity into it to carry as a spare . Is that a silly idea???
