76.8V 45Ah Lithium Battery Pack - Deep Cycle, Rechargeable, Fast Charging

This 76.8V 45Ah lithium battery pack is a deep cycle rechargeable battery built on LiFePO4 cells in a 24S2P arrangement, giving 3.456kWh of stored energy. It is designed as a fast charging lithium battery, accepting up to 30A of charge current, and can deliver 80A continuously with a 100A peak for demanding two-wheeler applications.

Deep, repeated discharge cycles are what this chemistry is built for, so the pack tolerates daily full-depth use far better than sealed lead-acid alternatives. Configuration, connectors and BMS protocol can be adjusted to your vehicle.

Deep Cycle Performance and Fast Charging

Deep cycle durability.

Rated for 1,200 deep discharge cycles, this rechargeable battery holds up to daily full-range use that would shorten a lead-acid battery's life.

Rapid recharge.

A 30A charge acceptance makes this a genuinely fast charging lithium battery; an empty-to-full session runs roughly 1.5 hours in theory, charger permitting.

Sustained high current.

80A continuous at 76.8V works out to about 6.1kW, with the 100A peak near 7.7kW (calculated at nominal voltage); real figures depend on the controller.

No upkeep required.

As a sealed, maintenance-free rechargeable battery, it skips the watering and terminal corrosion that come with lead-acid packs.

Wide climate range.

−20°C to 65°C discharge range keeps the pack usable across seasons.

Compact for its capacity.

3.456kWh in a 27.5kg housing keeps the energy density practical for two-wheeled frames.

Typical Uses for This Deep Cycle Battery Pack

The pack targets vehicles built around a 76.8V battery platform. Typical uses include:

Electric motorcycle upgrades

A drop-in rechargeable lithium battery pack for vehicles moving away from lead-acid.

Ride-share and delivery riders

Riders who need fast charging lithium battery turnaround between shifts benefit from the 30A charge rate.

OEM and ODM programs

Vehicle makers building a new 76.8V platform, or swapping in a deep cycle pack for an existing one.

Match this pack against your controller, charger and mounting space using the specification table above.

Send us your vehicle details if you want us to check compatibility first.

Customization for OEM and ODM Orders

We build this deep cycle rechargeable battery around your vehicle's requirements. Adjustable items include:

Pack voltage and capacity

Series/parallel cell arrangement

Fast charging current limit

BMS communication protocol

Case dimensions and connectors

Send your specifications or a vehicle drawing, and our team will confirm the configuration and feasibility before production.

BMS

BMS Protection and Communication

A built-in BMS covers overcharge, over-discharge, overcurrent, short-circuit and thermal protection, which is what allows safe deep cycle operation and fast charging without derating. CAN communication can be added, with the protocol customized to your vehicle's requirements on request.

Spare Parts

Controller and Charger Requirements

Check these three items before installing this 76.8V 45Ah lithium battery pack:

Controller input range covers 60–86.4V and handles 80A continuous / 100A peak.
Charger is set to an 86.4V cut-off and does not exceed the 30A fast charging current.
Wiring and connectors are rated for these current levels.

This pack is not tied to one controller or charger brand; once the numbers line up, it can work with the components already on your vehicle.

FAQ

Q1: Is this really a fast charging lithium battery?

Yes. It accepts up to 30A of charge current, giving a theoretical empty-to-full time of about 1.5 hours; actual time depends on the charger's taper stage.

Q2: How is it a deep cycle battery?

The LiFePO4 chemistry and 1,200-cycle rating are built for repeated full-depth discharge and recharge, unlike lead-acid batteries that degrade quickly under deep cycling.

Q3: What continuous and peak current does it support?

80A continuous and 100A peak at the rated 76.8V, which is roughly 6.1kW and 7.7kW respectively at nominal voltage.

Q4: Can this rechargeable battery replace my current pack?

If your controller accepts 60–86.4V and 80A/100A current, and your charger tops out at 86.4V within 30A, it's compatible. Send us your setup and we'll confirm.
