Something like this might work for you I saw this on the e bike choices site here https://www.ebikechoices.com/tongsheng-tsdz2-review/
Its a TSDZ 2 conversion but that shouldn't make too much difference. I would check your battery dimensions and clearances before committing, watch the front wheel when the suspension is compressed and note the additional straps to hold it on, I wouldn't rely on rivenuts or the case mount to hold the battery.

The rear rack mount option is pants.
One needs to bespoke build a frame bag or enclosure and then have a cell pack made to fit or look at enerprof.de for a 48v soft pack in a frame bag to see if it will fit.

I would move the rear shock front pivot to under the crossbar, clearing space for a standard downtube mount for the battery.

You might need a longer stroke shock to maintain travel.

I would not consider a rack battery although they do show one above the beneath the down tube option (the one I was referring to) I dont know a way of mounting one on a full sus bike.

I had thought of the softpack option as I have used the Enerpower solution with a 48v 15ah battery, in this case there doesn't seem the room to fit it . You can look on their website for the actual dimensions of the frame bag. I would also be very wary of using that company I found their customer service when dealing with a complaint very poor. If going down the softpack road better using a uk supplier. On the plus side if they get your order correct the battery and the bag are good quality, I was pleased with that part of my order. If you go for one of their combination battery in a bag deal you dont get the same item as if you order a soft pack battery alone. The batteries in the battery in a bag deals come without the led display and no switch.

I have heard this before about enerprof that CS isn't great, so much for German efficiency but that said the product looks good.

How to do that?

Carry it in a rucksack of large bumbag with a trailing wire plugging into the motor somewhere.

How to do that?

You would need to find someone with welding skills to make and fit a new bracket, or cut off and reweld the existing one.

If the frame is steel, this is easy. If it is aluminium, not so easy.

you'd have to measure it of course but maybe something like this would fit
