48V 67Ah Modular LiFePO4 Battery

The 48V 67Ah Modular LiFePO4 Battery works at the voltage that dominates the light electric vehicle market, and it is built to sit directly in that role. Two 25.6V 67Ah modules are connected in series to give 51.2V nominal at 67Ah, which is the usual working range for golf carts, scrubber dryers, floor machines, small forklifts and off-grid inverter banks.

The pack is modular in the same way as the rest of the Sinoah Energy range: each module carries its own BMS, protection and Bluetooth link, so capacity and voltage are set by how many units are connected rather than by the model ordered. Fleets converting from lead-acid can match the original pack voltage and then add capacity in parallel only where the duty actually needs it.

48V in Practice: Lower Current, Fewer Cables

Running the same power at a higher voltage means less current, and less current means thinner cables, cooler connections and fewer joints that can loosen. A 48V system assembled from two modules does the work of a 12V arrangement built from four, which shortens the install and removes failure points.

Parallel Expansion

Parallel units share the load, so each module discharges at a lower current and runs cooler. Where a fleet originally ran a large lead-acid bank, the lithium replacement can often be smaller in capacity for the same range because the usable depth of discharge is far greater.

Technical Specifications

Communication and BMS

Each module reports over Bluetooth, showing state of charge, cell balance, current and any recorded fault. Where several units run in parallel, the app lists them individually, so a weak module is identified before it affects the pack. The audible alarm at the machine warns the operator during use rather than leaving the fault for the next service.

Automatic balancing equalises cells inside a module and voltage between modules, which keeps a parallel bank in step without manual intervention. Fault diagnosis is automatic, and a module can be replaced on its own if it reaches the end of its life ahead of the others.

Applications

The 48V 67Ah Modular LiFePO4 Battery suits golf carts, utility carts and low-speed vehicles running 48V controllers.

Floor machines, scrubber dryers, aerial platforms and small electric forklifts with deep daily duty.

Caravan and marine house banks, and off-grid inverter systems where 48V is the standard DC bus.

Fleet Conversion Notes

Fleets converting from lead-acid usually keep the working voltage and change the charger to a lithium profile. Because the modules are sealed, there is no watering routine, no acid spill risk in the workshop, and no need for a ventilated charging bay. The weight reduction also shows up in machine run time, since less energy is spent moving the battery itself.

For fleet orders, Sinoah Energy confirms the number of modules per machine against the duty cycle and daily distance, and supplies dealer pricing on monthly bulk supply with warranty service handled in the UK.

Why Choose Sinoah Energy

Sinoah Energy is a UK-based supplier of LiFePO4 batteries and hybrid inverters, holding modular battery stock in the UK for dealers, installers and fleet operators. The modules are built to UN38.3 and UL1642 standards by NeoVolt, and the company provides OEM or ODM customisation where a fleet needs branded packs or a specific connector layout.

Technical support covers voltage and capacity selection, charger matching and pack layout before the order, and continues after delivery through app-based diagnostics and UK warranty service.

Charger Matching for 48V Packs

A 48V lithium pack needs a charger with a LiFePO4 profile and a voltage window that matches the pack, typically charging to around 58.4V for a 16S arrangement. Golf cart chargers, floor machine chargers and inverter chargers all exist in lithium versions, and the profile is selected rather than adjusted, since the module BMS controls the finish of the charge.

Where a fleet runs a mix of vehicles, the same 25.6V module can be used in 24V and 48V machines with different chargers in each bay. The module reports the charge and discharge history over Bluetooth, so the charger can be checked against the pack it serves.

FAQ

Q: Is the 48V 67Ah Modular LiFePO4 Battery one unit or two modules?

A: Two 25.6V 67Ah modules are connected in series to give the 48V system, which allows the pack to be reconfigured or extended later.

Q: How many can be connected in parallel?

A: Up to 20 units, giving a maximum of 1340Ah, with series strings limited to 102.4V.

Q: Will it work with an existing 48V charger?

A: The charger must be set to a lithium profile. Lead-acid charging profiles will not charge the pack correctly.

Q: How does it compare with a 12V bank for the same power?

A: A 48V pack uses fewer modules, fewer cable connections and lower current, which means less heat and fewer failure points.

Q: Is the battery waterproof?

A: The modules are rated IP67, so they tolerate washing and wet working environments, provided the connectors are kept clean.

Q: What is the warranty period?

A: 8 years, with diagnostics through the app and warranty service handled in the UK.
