4S 1500mAh 100C LiPo Battery with XT60 Connector Full Guide

If you’ve ever flown FPV drones, raced RC cars, or tinkered with high-power RC planes, you’ve probably bumped into the 4S 1500mAh 100C LiPo Battery with XT60 Connector. It’s one of those batteries that seems small, but packs a punch. I’ve used a few myself, and it’s worth understanding what you’re actually getting before you buy.

Specs at a Glance

Let’s break down the numbers, because they really matter:

• Voltage: 4S means four cells in series. Each cell has a nominal 3.7V, so total is about 14.8V.
• Capacity: 1500mAh – or 1.5Ah. Enough to give decent flight time without being a weight nightmare.
• Discharge Rate (C-rate): 100C continuous. That’s roughly 150A if you do the math (1.5 × 100). Some batteries also list a burst rating up to 200C. That’s for short, power moments.
• Connector: XT60. Standard, reliable, good for mid-to-high currents.
• Weight and size: Around 180–190g, dimensions roughly 35×40×77mm. Small variations exist depending on brand.
• Charge rate: Usually up to 5C max, meaning 7.5A for a 1500mAh battery. I generally stick to 1–2C to be safe.

Why People Like Them

Honestly, there’s a reason this battery is popular:

• High Discharge – That 100C rating isn’t just for show. Fast FPV quads, RC planes, or cars that want a sharp burst of power will love it. Burst ratings let you push even harder, short-term.
• Decent Capacity – 1500mAh is a sweet spot. Not too light, not too heavy. Enough juice for a few intense flights without bogging down your craft.
• XT60 Connector – Widely used, easy to swap, won’t fry itself under moderate load.
• Compact & Lightweight – Fits in mid-sized drones, keeps balance and agility intact.

What It’s Good For

If you’re wondering whether this battery fits your setup:

• FPV racing drones – especially 5-inch, 250mm frames. High current, quick response.
• RC planes or helicopters – aggressive maneuvers, short power bursts.
• High-speed RC cars – instant acceleration and top-end performance.
• Drones where you want a compromise between flight time and agility.

In short, anywhere you need high current without killing mobility, this battery works.

Downsides & Things to Watch

Nothing’s perfect. Even this one has trade-offs:

• Price – good batteries cost more. Don’t expect to find a 100C LiPo for cheap.
• Weight – 180–190g Drone battery is fine for most drones, but mini quads might feel heavy.
• Voltage limits – can’t put this in something rated for 3S (11.1V). That would be a problem.
• C-rate isn’t magic – 100C is theoretical. Real output depends on heat, internal resistance, and build quality.
• Safety – LiPos are finicky. Overcharge, over-discharge, or physical damage? Fire or swelling is possible. Charge in a safe place, monitor, never leave unattended.
• Storage – keep them at 3.7–3.9V per cell if not using for a while, or you’ll degrade the battery.

Digging Into the Numbers

• Voltage: 4S = 14.8V. Good for high-power setups.
• Capacity: 1500mAh balances weight and flight time. Bigger capacity = more time but heavier.
• 100C discharge: handles high-current draws for fast, aggressive use. Burst can go even higher.
• XT60: works, reliable, widely available.
• Charge rate: max 5C, safe practice is 1–2C.

Buying Tips

A few things I learned after testing these:

1. Match your device – check max voltage and current. Don’t force a 4S into a 3S setup.
2. Size & weight – make sure it fits your frame, battery compartment, or chassis. Don’t just eyeball it.
3. Brand matters – Rotor Riot, RDQ, CNHL are solid bets. Unknown brands? Maybe, but check reviews.
4. Connector & wires – XT60 is fine, but make sure wires are thick enough for your current draw.
5. Safety first – charge on fireproof surfaces, monitor while charging, discard if swollen/damaged.
6. Value vs performance – if you’re not racing or pushing max currents, a lower C-rate battery may be plenty.

Bottom Line

The 4S 1500mAh 100C LiPo UAV Battery with XT60 Connector is a versatile, powerful option for FPV drones, RC planes, and high-speed cars. It’s not the cheapest, and you need to respect LiPo safety, but for mid-sized models and aggressive setups, it delivers. Light enough for maneuverability, strong enough for instant power. Follow safety protocols, pick a trusted brand, and you’ve got a reliable battery that won’t disappoint.
