新西兰采购需求：电池管理系统、BMS电池、BMS模块、锂BMS、BMS锂电池、Lifepo4 BMS

I'm currently working with some Nissan Leaf batteries, and I've successfully connected them in series to achieve a solid 48V output. Additionally, when I combine them in parallel and utilize half of the battery capacity, I can support a load of up to 250A. Given these specifications, I'm looking for a Battery Management System (BMS) that would be suitable for my setup. Could you provide me with options for BMS products that would meet these requirements, along with the pricing details? I appreciate your timely response on this matter as I'm keen to proceed with my project.
