Racepow 4000mAh 4S1P 10C is a Li-ion battery with an excellent price/performance ratio. The battery is suitable for 4–5" drones, where it can provide a long flight time. The advantage of Li-ion batteries is their higher energy density – they offer more capacity at a lower weight. However, their lower discharge rates can be a downside. It’s important to apply throttle gently. Li-ion batteries are therefore ideal for relaxed flights – cruising or long-range. The minimum voltage per cell is 2.5 V, but we recommend landing with some margin at around 2.7 V per cell.
Before use, please read the Safety Guidelines for Using LiPo Batteries.
