LED1 flashing red
EGO CH5500E LED1 flashing red on 56V charger: fault state
Risk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
On the EGO Power+ CH5500E 56V rapid charger, LED1 flashing red while LED2, LED3, and LED4 stay off indicates a bad connection between the battery pack, adaptor, and charger, or that the battery pack, adaptor, or charger is defective.
Safety first
Stop and check this first
- Never attempt to disassemble the CH5500E charger or touch the uninsulated portion of the output connector or uninsulated battery terminal; always unplug the charger from the outlet before attempting any cleaning or maintenance.
- Do not operate the charger if it has received a sharp blow, been dropped, or been damaged in any way (take it to an authorized service technician for an electrical check), and never dispose of defective battery packs in household waste.
Safe checks you can perform
- Distinguish LED1 flashing red from LED1 shining solid red
- Remove and reinsert the battery pack on the charger mounting slot
- Try to charge a different compatible EGO 56V battery pack
- Unplug the charger from the 220-240 V~ power supply until the red LED1 goes out
Leave these tasks to a qualified professional
- Do not attempt this professional task: Electrical check and servicing at an EGO Authorized Service Center
- Do not attempt this professional task: Authorized supply cord replacement and separate collection under European Directives
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Electrical check and servicing at an EGO Authorized Service Center
What they doA qualified service technician performs an electrical check on the CH5500E rapid charger (5-8 A, 56 V output) and the battery pack or adaptor, using only identical replacement parts.
They must show youthe electrical check result confirming whether the fault lies in the CH5500E charger, the adaptor, or the battery pack.
In writingthe EGO Authorized Service Center report documenting the electrical check and any identical replacement parts installed.
Authorized supply cord replacement and separate collection under European Directives
What they doIf the supply cord is damaged, it is replaced by the manufacturer or its service agent; defective or exhausted battery packs and electrical equipment are collected separately in compliance with European Directives 2012/19/EU and 2006/66/EC.
They must show youthe external inspection of the supply cord, plug, and terminals without disassembling the charger housing at home.
In writingthe authorized service record or the separate collection receipt for the defective battery pack under Directive 2006/66/EC.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Distinguish LED1 flashing red from LED1 shining solid red
- Who:
- you, observing the four charging indication LEDs on the CH5500E charger.
- How:
- check whether LED1 is flashing red (defective) or shining solid red; solid red simply indicates a cold or hot battery pack and charging will begin automatically once the temperature of the battery pack returns between 3 °C and 57 °C (3 °C to 50 °C for BA2240T; 3 °C to 42 °C for BAX1300).
- Result that matters:
- you confirm whether LED1 is flashing red for a fault or shining solid red while waiting for normal temperature.
- If LED1 is shining solid red:
- allow the battery pack to reach normal temperature (optimum charging ambient is 5 °C to 40 °C).
- If LED1 is flashing red with LED2, LED3, and LED4 off:
- proceed to remove and reinsert the battery pack.
- Evidence to keep:
- short video showing whether LED1 is flashing red or shining solid red.

Remove and reinsert the battery pack on the charger mounting slot
- Who:
- you, with dry hands in a well-ventilated indoor area.
- How:
- try to remove and reinsert the battery pack on the charger (disconnect and reconnect the adaptor for model BAX1300), aligning the raised ribs on the battery pack with the mounting slots without touching uninsulated terminals.
- Result that matters:
- the charger communicates with the battery pack and the four charging indication LEDs shine green in sequence, from left to right.
- If the four LEDs shine green in sequence and the cooling fan runs:
- it was a bad connection.
- If LED1 flashes red again:
- try to charge a different compatible EGO battery pack if available.
- Evidence to keep:
- exact model number printed on the 56V battery pack rating label.

Try to charge a different compatible EGO 56V battery pack
- Who:
- you, if you have a second approved EGO 56V battery pack.
- How:
- insert a different compatible EGO 56V battery pack (from the manual list: BA1120E, BA1400, BA1400T, BA2240E, BA2240T, BA2242T, BA2800, BA2800T, BA3360, BA4200, BA4200T, BA5600T, BA6720T, or BAX1300) into the CH5500E charger.
- Result that matters:
- you check whether a second battery pack charges normally on the same charger.
- If the second battery pack charges normally:
- the first battery pack or adaptor is defective and should be taken to an EGO Authorized Service Center.
- If the second battery pack also fails to charge:
- unplug the charger and wait until the red LED1 goes out.
- Evidence to keep:
- comparison of LED1 behavior between the first and second battery packs.
Evidence: Manual del usuario y Operator's Manual Cargador rápido de 56 V EGO CH5500E (MNL_EGO_CH5500E_EV02.31_260120)
Unplug the charger from the 220-240 V~ power supply until the red LED1 goes out
- Who:
- you, pulling the plug rather than the cord when disconnecting the charger.
- How:
- remove the battery pack, unplug the charger from the 220-240 V~ 50 Hz power supply, and wait until the red LED1 goes out; then reconnect the plug to the power supply.
- Result that matters:
- all four charging indication LEDs briefly shine green when reconnected, indicating that the charger is working properly.
- If reinserting the battery pack starts normal sequential green charging:
- the fault state cleared.
- If LED1 on the charger still displays defective:
- take the charger to an EGO Authorized Service Center for service.
- Evidence to keep:
- note of whether all four charging indication LEDs briefly shone green upon reconnecting the plug.

What it means
The EGO Power+ 56 Volt Rapid Charger CH5500E Operator's Manual (document MNL_EGO_CH5500E_EV02.31_260120, covering battery packs BA1120E, BA1400, BA1400T, BA2240E, BA2240T, BA2242T, BA2800, BA2800T, BA3360, BA4200, BA4200T, BA5600T, BA6720T and BAX1300) states that if the charger detects a problem, LED1 will begin flashing red (or all the LEDs will turn off) while LED2, LED3, and LED4 remain off, indicating that the battery pack or charger is defective. Other models may vary, and this indicator state alone never proves a part is defective.
Warnings and stop conditions
- Higheditorial warning
Never attempt to disassemble the CH5500E charger or touch the uninsulated portion of the output connector or uninsulated battery terminal; always unplug the charger from the outlet before attempting any cleaning or maintenance.

Symptoms and causes
Probable causes · in order
- Bad connection between the 56V battery pack, adaptor, and CH5500E chargerCommon
If the mounting ribs of the battery pack (or the adaptor for model BAX1300) are not properly seated in the mounting slots of the CH5500E charger, a bad connection triggers LED1 flashing red.
Evidence: Manual del usuario y Operator's Manual Cargador rápido de 56 V EGO CH5500E (MNL_EGO_CH5500E_EV02.31_260120)
- Defective 56V lithium-ion battery pack or BAX1300 adaptor identified during evaluationPossible
The charger communicates with the battery pack to evaluate its condition; if a second battery pack charges normally on the same CH5500E charger, the manual states that the first battery pack or adaptor is defective.
Evidence: Manual del usuario y Operator's Manual Cargador rápido de 56 V EGO CH5500E (MNL_EGO_CH5500E_EV02.31_260120)
- Latched fault or internal failure in the CH5500E rapid charger (220-240 V~, 50 Hz, 550 W)Possible
If LED1 on the charger still displays defective after unplugging the charger from the power supply, waiting until the red LED1 goes out, and reconnecting the plug, the charger itself requires authorized service.
