Buy offer Details

I have an old Electric Scooter that requires upgrading through replacing the existing LiFePo4 72v 8000w batteries BMS and Charger. The battery pack sits inside and steele rectangular housing dimensions are 770 L*225 W*230 H Fixed above this Battery box which is open at the top is the Charger and BMS, along with the SEVCON Gen 4 80v 350amp controller.
Can you tell me the most powerful and long lasting, along with fastest recharging 72v setup you can configure into this space and the cost to ship to Melbourne, Australia. The importer is no longer in business, nor is the manufacturer in China.
The importer sold over 200 of these units over 6 years ago, and so there is good opportunity in supplying this configuration to that group of purchasers given the lifecycle coming to an end for their power sources.
Kind Regards,
