Need help with ideas for making a shell for my scooter battery
Hello everyone. I am disabled by epilepsy and can not drive a car. I get around on an electric scooter and bike. Currently my scooter gets about 60 miles to one charge and I would like to double it to 120 miles for large trips. It would make a huge difference in my life and enable me to get to neighboring towns I currently can not get to.
So I come here to you all hoping for practical suggestions. I want to lay a 2nd battery on top of where I stand and make some kind of shell that can fasten to the scooter to protect it from my weight. The battery is about the length of the scooters center.
If you google an flj k3 scooter you can see what I am working with....... SCOOTER LINK

Many long range scooters I've seen put the extra battery on the vertical post. That way you can use the scooter without the extra pack when it's not needed and you just hang on the extra pack for those long range days. It also removes you from the need to make a protective enclosure strong enough to stand on if you put it on top of the scooter's main body.

Welcome to the forums.
To post pictures here....... How-to-insert-pictures.
I added a link to the scooter in your thread.
When I went to that site and looked at that scooter...... they discuss it with larger batteries for more capacity. It looks like they can fit larger cells into the existing area.

Personally I like Pilot Dane's suggestion adding a battery to the vertical post.
If that will not work for you I would say you will need to make a box out of aluminum to house the battery.
The 2nd battery will need to be the same voltage as the existing battery if you are paralleling them.

I've been searching to find more information. There is the typical lack of any technical info on China built/supplied products.
This scooter uses a 60v battery pack. It's not going to be easy to add a second pack. I tried to find a picture of the inside of that scooter to see what size the original pack is. Didn't find any pictures. I can't even locate a user manual.
It looks like Ali Express is handling most of the spare parts and technical info.
I did locate what the battery pack looks like. It is not going to be as easy as just connecting two battery packs together.

I do not think that adding it to the floor board would be a good idea as it will raise you center of gravity and could make the scooter unstable.

I would think to put a battery and to raising the center of gravity a few inches would be better than on the vertical part, but I would suspect either wouldn't make much of a difference since the rider is likely 10x the weight of the battery.
The OP will have to test things out and see what works best.

If I was doing this I would get two batteries or one battery and something of the same size and weight and mount them like saddlebags under and on each side of the deck.
I would strongly advise you to get the battery or batteries and mock it up before spending big dollars on metal enclosures etc. Having extra range will not be a plus if you have to fight with it to ride it.

You don't say how you will connect this second battery but there are a few things for you to consider.
If you plan to permanently connect the two batteries together they would need to be identical batteries and both need to be the same age and condition or they will not properly charge.
You would also need to make sure your charger has enough capacity to charge them both.
The best way to connect them would be with a connector to allow you to use and charge each battery separately.
