Learn about how to manage ERS in F125

Updated October 1, 2025

If you’re struggling with how to manage ERS in F125, you’re not alone. It feels like the battery empties at the worst moments, or the overtake button does nothing. That happens because F1 25 limits how much energy you can deploy each lap and when you can deploy it. This guide will make ERS simple so you know exactly when to save, when to push, and which buttons to press.

Quick Answer

Use a dedicated, easy-to-reach button for ERS Overtake. Keep battery between 20–80%. Deploy in short bursts on the exits of long straights (especially with DRS) and turn it off before braking boards. Save a lap if you drop below 20%. Don’t hold Overtake all lap—there’s a per‑lap deployment limit.

Why how to manage ERS in F125 Feels So Hard at First

ERS has both a battery level (state of charge) and a strict per‑lap deployment limit. You can hit the lap limit even if the battery still shows charge.
In F1 25, deployment is mostly controlled by a single Overtake button, so timing and discipline matter more than menus.

By the end, you’ll know how to plan your battery lap-by-lap, nail overtakes, and stop getting that “ERS unavailable” message mid‑straight.

What how to manage ERS in F125 Actually Means in F1 25

ERS (Energy Recovery System): A hybrid battery that adds electrical power for short bursts.
State of Charge (SOC): The battery percentage on your HUD.
Per‑Lap Deployment Limit: Even with charge left, there’s a maximum amount you can deploy each lap. Use too much early and you’ll get limited until the next lap.
Harvesting: The game automatically recharges under braking and off‑throttle; you don’t set harvest levels manually.
Overtake (OT): Your push‑to‑pass. It increases deployment rate while it’s on.
DRS + ERS: Opening DRS reduces drag; pairing it with ERS gives the best straight‑line gains per unit of energy.

On screen, look for:

A battery icon/percentage and a deployment bar.
An OT or “Overtake” indicator when it’s active.
Messages like “ERS Unavailable” when you’ve hit the per‑lap limit or the battery is too low.

Before You Start (Prerequisites)

Hardware:
- Controller or wheel with a thumb‑ or paddle‑button reserved for ERS Overtake.
Game/Mode:
- Works the same in Time Trial, Grand Prix, Career, and Multiplayer.
- Assists can automate ERS; turn them off if you want manual control.
Menus you’ll use:
- Settings > Assists: Set ERS Assist to Off for manual control (or On if you want the game to manage it).
- Settings > Controls > Edit Mappings: Assign ERS Overtake to a convenient button.
- Preferences/OSD/HUD: Ensure the ERS/Battery widget is visible.
- On‑track MFD/HUD: Use the D‑pad to cycle until you see battery/SOC info.

Step-by-Step: How to Fix / Improve how to manage ERS in F125

Map the Overtake button

Open Settings > Controls > Edit Mappings.
Assign ERS Overtake to a large, easy thumb/paddle button.
Tip: Avoid mapping it to bumper combinations you might hit by accident.
Success check: Pressing the button on track shows an OT indicator and a stronger deployment bar.

Choose manual or assisted ERS

Go to Settings > Assists.
Set ERS Assist to Off for full control, or On to let the game deploy automatically.
Success check: With Assist Off, ERS never turns on unless you press your Overtake button.

Turn on the ERS HUD

Go to Preferences/OSD/HUD and enable the Battery/ERS widget.
Success check: You see battery % and a deployment bar during laps.

Learn your targets

Aim to keep the battery between 20–80% in races.
If you finish a lap under 15–20%, plan a light “recharge lap” next time around.

Deploy in the right places

Use short bursts of Overtake:
- On corner exit when the car is straight (3rd gear or higher).
- Down long straights, especially if DRS is active.
- Turn it off before the 100m board (or earlier) to save energy.
Don’t deploy:
- Mid‑corner or on traction‑limited exits.
- When you’re about to hit the rev‑limiter at the end of a straight.
Success check: Your speed gains occur where they matter most, without triggering “ERS Unavailable” before the braking zone.

Plan for different scenarios

Overtaking: Save to 50–70%, use DRS + short ERS bursts to complete the pass, then switch off.
Defending: Use a small burst early on the straight to break the rival’s slipstream, then off.
Recharge lap: Keep Overtake off everywhere for one lap; brake firmly and avoid wheelspin. Battery should climb back above ~40%.

Qualifying routine

Out‑lap: No ERS.
Hot lap: Pre‑arm ERS before the final corner or toggle on at the line. Use it on the main straight and the biggest straights only—don’t waste it in medium‑speed corners.
Cooldown: ERS off to recharge.
Success check: You reach the final sector with enough energy left to finish the lap strong.

Wet or low‑grip conditions

Use shorter, gentler bursts; prioritize traction.
If rear tires are slipping, ERS is hurting more than helping—wait until the car is straight.

Watch for per‑lap limit behavior

If you see “ERS Unavailable” mid‑straight:
- You likely used too much earlier in the lap.
- Next lap, delay your first burst or shorten earlier ones.

Common Mistakes and Myths About how to manage ERS in F125

Holding Overtake the whole lap: You’ll hit the per‑lap limit early and be slow where it matters.
Spamming ERS out of slow corners: Wheelspin wastes energy and overheats tires.
Finishing a lap at 0%: Leaves you defenseless and slow next lap.
Forgetting to turn it off: Easy way to drain the battery without lap time gain.
Thinking “more ERS = faster lap everywhere”: It’s fastest on straights and exits, not mid‑corner.
Using ERS when already at top speed/rev‑limiter: No benefit—save it.

Troubleshooting and “What If It Still Feels Wrong?”

Overtake doesn’t activate
- Likely cause: Battery too low or per‑lap limit reached.
- Fix: Save for a lap; try shorter bursts later in the lap; ensure ERS Assist is Off if you want manual control.
- Note: ERS is restricted in the pit lane and during some scripted moments (e.g., parts of the formation lap).
Battery drains way too fast
- Likely cause: Overtake left on, or you’re deploying in too many places.
- Fix: Use 1–3 second bursts only; prioritize the two longest straights; check your control mapping isn’t double‑bound.
Battery never seems to recharge
- Likely cause: You never commit to a true recharge lap.
- Fix: One full lap with Overtake off. Brake firmly and smoothly; avoid wheelspin on exits to improve harvest.
Can’t see battery info on HUD
- Fix: Enable the ERS/battery widget in Preferences/OSD/HUD; use the D‑pad to cycle MFD pages until battery % is visible.
Changes won’t stick
- Fix: Save your custom control profile after remapping.
- Note: If your settings revert after a restart, re‑select your device profile before loading into a session.

What not to do:

Don’t max the battery to 0% to set a single lap—race pace suffers for multiple laps after.
Don’t deploy mid‑corner or while correcting oversteer—wait until the wheel is straight.

Pro Tips Once You’re Comfortable

Micro‑bursts: 0.5–1.0s taps on exits keep speed building without tripping the per‑lap limit.
DRS trains: Sit in DRS to save ERS, then attack when the car ahead loses DRS to the pack.
Track‑by‑track plan: On high‑speed tracks (Monza, Jeddah), save for the biggest straights. On twisty tracks (Monaco, Hungary), fewer good deploy spots—be even stricter.
Start/finish line timing: Toggle ERS just before or at the line in qualifying to front‑load deployment into the lap’s longest run.
Car setup interplay: Higher downforce often needs a bit more ERS to hit competitive top speeds; lower downforce needs less ERS but offers fewer harvest opportunities due to lighter braking.

How to Know It’s Working (Definition of Done)

You finish most race laps with 20–60% battery, not 0–5%.
You rarely see “ERS Unavailable” before the final braking zone.
Your overtakes happen with DRS + short ERS bursts, and you can still defend the next lap.
In qualifying, you reach sector 3 with enough energy to deploy to the line.

Now that how to manage ERS in F125 is dialed in, the next big gain usually comes from DRS timing. See our guide on F125 DRS usage and rules.
