Warm Tips:(Battery not included)
1.The 7S requires a 29.4v charger.
2.Do not use it on metal table top, pay attention to insulation and do not short circuit.
3.The charging current of each layer is not recommended to exceed 2a, otherwise the battery may generate heat (for example, if there is only one layer, choose 2a charger, and if there are two layers, choose 4a charger).
4.Look at the circuit board with the battery orientation,and all the batteries cannot be staggered in the same orientation.
5.Don't connect the power supply with the wrong positive and negative, there are signs on the circuit board, pay attention to observation.

Let customers speak for us
from 614 reviewsExtremely Disappointed – Terrible Service, No Delivery After 1 Month!
Review:
I am beyond frustrated with this shopping site. I placed an order over a month ago, and I have yet to receive the product. The lack of communication and failure to fulfill the order is completely unacceptable. I have sent multiple inquiries with no proper response. This is the worst shopping experience I have ever had.
I strongly advise others to avoid this site, as they clearly cannot handle basic customer service or delivery. If you value your time and money, do not waste either here.
This company has absolutely no regard for its customers. I expect a full refund, or I will be forced to take legal action. Do yourself a favor and shop elsewhere.
