Tidalforce Wavecrest Front Hub Disassembly

I'm trying to replace the NiMH cells in a front A hub battery. So far, I've gotten the cover off, however, i can't figure out how to remove the actual battery/bms from the battery case/wheel. It seems to be bolted one and I suspect you need a special tool in order to extract it, however, I thought I'd ask first!

If you know how to do this, please drop me a line at:

(replace the "AT" with @ and "DOT" with "."

Thanks!
