On the Jiangxi side, I usually start by contacting local experts in the ham industry to help me DIY the battery. My "wild-built" battery is 14.4V 50Ah, consisting of four series of lithium iron phosphate batteries, and supports USB-PD fast charging, cigarette lighter discharge, XT60 discharge, DC charging, with voltage display and a matching charger. The cost is around 500, although it's slightly heavier, the value for money is still quite high.
I also joined a group for gum battery accessories, loose parts, and was told that I needed to purchase the batteries separately. The price seemed to be around 300 yuan (RMB), with a capacity of 5-10Ah, but the price was relatively high. The advantage is that they are more portable. Previously, they were only available as pre-orders, and I heard that they are currently being updated. Overall, the value for money seems to be average.
