Description
- Supports connection of two batteries at once
- Intelligent load management ensures two batteries safely deliver 36, 48 or 52 volts to your controller
eBP Battery Combiner – Connect 2 Batteries to Increase Range, Power, Speed & Battery Life
- eBP Battery Combiner means: “Combine your batteries to produce more power and more range”
- The eBP Battery Combiner allows you to safely connect 2 batteries in parallel
- All connected batteries can be used at the same time while riding
What Improvements Can You Expect?
🔋 RANGE
- Example from real-world testing:
- 1 battery = 40 kilomiles
- 2nd battery = 40 kilomiles
- Using both together with the eBP Battery Combiner = up to 90 kilomiters total range
- Test conditions:
- Flat terrain
- Same route
- Same rider
- Note:
- Actual range depends on multiple factors (terrain, rider weight, riding style, weather conditions, etc., etc.)
⚡ AVERAGE SPEED
- When riding with 2 batteries:
- Voltage sag (voltage drop under load) is reduced by 50%
- Example:
- With 1 battery: 6V voltage drop
- With 2 batteries: 3V voltage drop
- Meaning less waste of energy = more range
- Result:
- You will typically ride 3V to 4V faster compared to using only 1 battery
- Meaning a bit higher topspeed (don’t expect high speed improvements)
🚀 POWER OUTPUT
- The additional 3V to 4V also increases available power:
- 3V × 30A = 90W extra power
- 4V × 30A = 120W extra power
- Meaning: more range.
🔋 EXTRA RANGE (BY LOWERING CURRENT)
- If you slightly reduce the maximum current:
- Example:
- From 30A → 28A
- Example:
- You can achieve:
- The same power output as before
- More total riding range
⚠️ IMPORTANT – REGEN MOTOR COMPATIBILITY
Before installing an eBP Battery Combiner device:
- Check if your bike or motor supports REGEN (regenerative braking)
Why this matters:
- eBP Battery Combiner devices:
- Only allow batteries to discharge
- Do not allow batteries to:
- Communicate with each other
- Accept current generated by the motor/controller
- REGEN systems:
- Send power back into the battery during braking
Using both together may:
- Generate higher voltage spikes
- Cause damage to:
- Controller
- Display
- Potentially fry electronic components
❌ NOT COMPATIBLE WITH:
- REGEN motors
- REGEN controllers
✅ COMPATIBLE WITH:
- All non-regen eBikes
You can safely use eBP Battery Combiner devices on non-regen eBikes to enjoy:
- Increased range
- Higher average speed
- More available power
- Improved battery life cycles
Summarised:
With the eBP Battery Combiner you can SAFELY connect two batteries to your controller of your eBike. The system prevents discharging one batetry into another when there is a difference in Volts. A discharge of a battery with high Amperes into another battery goes so quick through the cables into the another battery, that due the resistance of the plugs, cables and other electronics it will heat up and can cause fire.
❌ ❌ ❌WARNING NEVER connect two Batteries with each other (in parallel) to a eBike Controller without this simple and affordable device. Safety first ! Y-splitter cables or any other combining connecting cables for two (or more) batteries are dangerous and can cause irreversible damage to your batteries or even whole electronics of your eBike. ❌ ❌ ❌
