Customer Reviews
This is the best battery i have ever purchased on aliexpress. The ones i bought before either didn't ship or had very low capacity, making the riding experience very poor. This seller's battery is really good.
Ordered a 72v 60ah 100a discharge battery, the label on the battery clearly says the same thing, battery is actually a 72v ~15ah battery with 60a discharge.
I am a qualified experienced professional and all safety precautions were taken to ensure that all tests are accurate and completed safely.
The battery lasts over 120km, really good.
Excellent battery and delivery
I am very satisfied
The seller gives me all the details that i ask for and he helped me to choose the right battery. the battery seems good quality, still i didn’t install it yet, once installed i’ll right a further review. thanks
