48V 27Ah NMC Lithium Battery Pack | Custom Lithium Battery Assembly for E-mobility

Brands that build e-mobility vehicles usually need more than a catalog battery. This 48V 27Ah NMC pack from TENZ ENERGY gives you a defined electrical base: about 1,296Wh, a 13S6P layout, 7.2kg and up to 45A of discharge. Through custom lithium battery assembly, we can build it into a fixed case or a lift-out format, so it works as a 48V removable e-mobility battery where your vehicle has a bay made for it. Tell us your bay, plugs and controller, and we will propose the build.

OEM/ODM Customization and Applications

Custom Lithium Battery Assembly for E-mobility Brands

The specification above is the starting point, not the limit. TENZ ENERGY assembles lithium packs to your vehicle plan on an OEM/ODM basis, using this 48V 27Ah build as the reference or developing a new design from scratch.

Case and format. Choose a fixed case for built-in installs or a lift-out case with handle and docking plugs for vehicles with a battery bay.
Pack size. A different voltage, capacity or cell layout is checked by our engineers against your power and runtime targets.
BMS setup. Protection limits, current thresholds and communication interfaces are set up for your controller and charger.
Charging profile. If you need a fast charging lithium battery, tell us your target charge time. The standard pack here charges at 3A with a 5A maximum, and any higher rate is assessed by engineers against the cells and BMS before it is offered.
Plugs and cables. Charging sockets, discharge plugs and cable lengths can follow the parts your vehicle already uses.
Branding. Labels and cartons can carry your brand.

A bay photo, a drawing, a sample pack or a controller datasheet is enough to open the discussion.

E-mobility Uses

This pack is built around 48V e-mobility projects such as light scooters, electric bicycles and light two-wheelers, where the controller, current draw and mounting space agree. Heavier vehicles generally need a larger custom battery.

What You Get with This 48V Lithium Battery Pack

A Defined Electrical Baseline

Voltage, capacity, current limits and temperature windows are all set out in the table, so your controller and charger choices can start from real numbers.

1,296Wh at 7.2kg

The pack carries about 1,296Wh in a 7.2 ± 0.1kg body, giving designers a lightweight energy block to work around.

45A Discharge Headroom

At 48V nominal, a 45A maximum corresponds to about 2.2kW. Ask us how long the pack can hold that current before you fix controller limits.

A Charging Profile You Can Plan Around

Charging stops at 54.6V, with 3A as the standard current and 5A as the ceiling. A reliable charge window lets you size the charger and the charging time of your vehicle.

Format That Matches Your Bay

Whether your vehicle needs a built-in pack or a 48V removable e-mobility battery, the case and plugs can be shaped to suit.

FAQ

Q1: What electrical baseline does this 48V lithium battery pack offer?

It is an NMC pack in a 13S6P layout with a 48V nominal voltage, 27Ah rated capacity (26.1Ah minimum) and about 1,296Wh of energy. Maximum discharge current is 45A, and the weight is 7.2 ± 0.1kg.

Q2: Can this be built as a 48V removable e-mobility battery?

Yes, as a custom case. If your vehicle has a slide-in or lift-out bay, we can design a case with a handle and docking plugs. If the battery is installed permanently, we supply a fixed case instead.

Q3: Is this a fast charging lithium battery?

The standard pack charges at 3A, with 5A as the maximum, and is not specified as a fast-charge product. If your project needs a higher charge rate, tell us your target and our engineers will assess whether the cells and BMS can support it.

Q4:What can be changed in custom lithium battery assembly?

Case outline, plugs, cable length, BMS settings, labels and packaging can be adapted. Changes to voltage, capacity or cell layout are checked against your power and runtime needs first.

Q5: How does the BMS protect the pack?

Protection covers overcharge, over-discharge, overcurrent, short circuit and temperature limits. If your controller needs CAN or another interface, include it in your request.
