澳大利亚采购需求：电池管理系统，BMS电池，BMS模块，锂BMS，BMS锂电池，适用于Lifepo4的BMS

We're seeking clarification regarding the BMS model we have on hand. Specifically, we want to know if it's feasible to extend the balanced wire sense cables. We've heard conflicting views on this, particularly about the importance of exclusively using balancing wires from the manufacturer. If extending is possible, could you advise on the appropriate wire gauge in both AWG and mm²? Additionally, we need some guidance on accessing the instruction manual and obtaining the software for the Bluetooth attachment for this BMS model. Any links or resources you could provide would be greatly appreciated. Thanks!
