Question:
    Dear Sir, My friend introduce your lipo batteries to me . I am not a specialist about Li-Po battery, I don't understand much about it. In R/C aircraft model ,don't you need protection circuit in Lipo batteries? Why they use protection circuit if you don't need it? Is your Li-Po battery will not be inflating? It's great if battery will not inflating. Looking forward your reply , Best Regards.
Answer:
    Dear Amy, Thanks for your email. Mostly batteries will be inflating if charged improperly. For this reason, we have a design of protection circuit in our chargers but not in batteries. A protection circuit in a battery will possibly lead to a crash especially for an aircraft model. Please feel free to contact our authorized distributor, World Model, in Hong Kong for service.
