48V AmpBox DIY Lifepo4 Battery BOX With JK16S BMS with LCD Screen

Great product, very well constructed. Should have picked up an extra one, at the price that I paid. Easy to operate and would recommend it to others.

So far so good

Been working great, waiting for some terminal covers contacted customer service and said they are working on it. Probably will order another very soon

AmpBox DIY (not)

Received box in good condition after having to wait for BMS resupply. Build quality seems top notch. A few helpful hints: 1. App name is tricky because it starts with Chinese symbols. Search “BMS” and look for blue cloud. 2. Upon first startup of the app the PW is “1234”. 3. Subsequent app usage requires PW of “123456” to modify settings. Other than that, seems like a great battery.
