HUAYPG 3500mAh 7.4V Upgrade Battery for MN RC Models – SM3P

Give your compatible MN RC model more runtime with this HUAYPG 7.4V 3500mAh lithium-ion upgrade battery. It uses 18650 cells and the same three-wire SM3P plug used by the verified MN battery setup, so no connector modification is needed.

Two ways to upgrade: Some MN models come with smaller 7.4V packs using 14500 cells; where the compartment has room, this 18650 pack provides higher capacity. Other models, including MN168 and MN128 as identified by the seller, already use 18650 packs rated around 1000–1200mAh. This 3500mAh pack increases capacity in the verified setup.

Fit: The connector has been verified as plug and play. Battery compartment size and placement can vary by MN model, so compare physical dimensions with the original pack before ordering for a model whose fit has not yet been confirmed.
