Xietongpo 54.6V 3A Charger for 48V Li-ion Battery Packs — 4 Interchangeable Plugs, LED & Safety

The Xietongpo 54.6V 3A charger is a compact AC-to-DC power adapter built to fast-charge 48V (13S) lithium Li-ion battery packs with four interchangeable output plugs and multi-layer safety protection.

This charger accepts 100–240V AC input and outputs 54.6V at 3A, making it suitable for charging 48V lithium battery systems used in e-bikes, scooters, mobility devices, and DIY battery packs. It is not designed for lead-acid batteries. The unit includes LED status indication and six safety protections to reduce risk while charging. Multiple connector options simplify compatibility with different devices without needing separate adapters.

Which devices will this 54.6V 3A charger work with?

It’s engineered for 48V lithium (13S) Li-ion battery packs. The charger comes with four common output heads so you can match the charging port on many commercial and custom battery systems. Always confirm your battery chemistry and connector type before use.

• Designed for 48V (13S) lithium Li-ion battery packs
• Not suitable for lead-acid battery chargers
• Includes 5.5×2.5mm and 5.5×2.1mm DC male plugs
• Also includes an 8mm 3-prong female plug and a 3-pin XLR male connector

How fast and how will I know when charging is complete?

The charger supplies a steady 54.6V at up to 3A, which provides a practical charge rate for many 48V packs without overstressing cells when used correctly. An on-board LED gives a clear visual charge status so you don’t need extra tools to check progress.

• Output: 54.6V DC, 3A maximum for consistent charging
• Red LED when charging; green LED when charging completes
• Stable voltage suitable for 13S lithium configurations
• Ideal for regular top-offs and full recharge cycles within recommended limits

What safety features protect my battery and charger?

The Xietongpo charger includes multiple hardware protections to minimize common charging risks. These protections help prevent damage from electrical faults and thermal stress, improving safety during routine charging sessions.

• Overcurrent protection to limit excessive charging current
• Overvoltage and overcharge protection to protect battery health
• Short-circuit and reverse protection to prevent wiring mistakes
• Overheating protection to cut power under high-temperature conditions

How do I choose and attach the correct connector?

Refer to the connector diagram in the product details and download the user manual from the product page before first use. If you’re unsure about plug gender or pin sizing, measure your device’s charging port or contact support to avoid mismatch.

• Connector options: DC 5.5×2.5mm, DC 5.5×2.1mm, 8mm 3-prong female, and 3-pin XLR male
• Check port size and gender against connector images before plugging in
• User manual PDF available on the detail page for step-by-step guidance
• Contact seller support if you need help identifying DC2.1 vs. DC2.5mm pins

Who is this charger for? If you own or service 48V lithium (13S) battery systems and need a single, portable charger that covers multiple connector types, this Xietongpo 54.6V 3A charger is a practical choice. It fits e-bikes, scooters, mobility aids, and custom battery packs where a 54.6V/3A supply and connector versatility are required. Avoid using it on lead-acid batteries and always verify connector compatibility and battery chemistry before charging.
