英国采购需求：电池管理系统、智能BMS、主动平衡器、电池均衡器、点焊机、电池修复器

I'm interested in placing an order for two specific types of lithium-ion battery packs. I'm looking for a configuration with a 10-series and 2-parallel setup, as well as another with a 7-series and 3-parallel setup. It's essential that both packs come with the appropriate BMS for optimal performance. Could you please confirm if you have these battery packs available? Additionally, I would appreciate it if you could provide the pricing details for both options, along with any bulk discount opportunities and lead times for shipping. This info will help me make a quick decision. Thanks!
