Help re battery replacement

I brought off eBay a wheelchair tractor. It is brilliant but.. The range is less than needed and as this bit of kit turns a wheelchair into a powered trike I thought a second battery would double its range. The problem is sourcing the same. It has the number HH36-9M on it. Is there anybody i could contact to solve the issue. Alternately would anyone suggest getting a new battery, a carrier for the same and a matching case to transfer the cells from the current case into to achieve the same ends?

Hi, contact Jimmy at

He will be able to recell your current battery and maybe make you a new one.

Send him pictures of current battery and volts / amps details.

Hope this helps.

Show us a pic of your current battery as then we can try and give you some suggestions or supply a link for us to view the kit.

I'm purely guessing here but assume HH36 -9M is a Hailong 36v 9ah battery ?
If so then Hailong's are a commonly used case and you can use any 36v ah/capacity rated battery so do not have to stay with a lowly 9ah. Ah/wh is just a capacity rating and a higher rated battery will work giving extra range.

It's almost certain that you can use any 36v capable of delivering 20 amps as long as you can find a way to attach and connect it. (Jimmy) can take out whatever is in your battery and reload it with lithium cells for around £250, depending on what characteristics you want from it (life, weight, power, capacity). You can call him to discuss options. he provides a pickup and return service, so the whole thing takes about a week or less.
