I had a quick question. Would it be fine to use a basic Bluetooth speaker charging circuit for a larger battery? The original battery is a 3.7v Li-Po at 300 mAh and the one I want to use is a 3.7v Li-Po at 4000mAh. Would it charge properly and would it charge to the max? Can I use the leads from the larger battery or would I need new ones?
