Custom 72V 58.8Ah Lithium Ion Battery Pack

A 72V 58.8Ah lithium-ion pack for electric construction vehicles, marine propulsion and other heavy mobile equipment; packs at this voltage also serve larger golf and utility carts. It carries 4.23 kWh of usable energy and delivers 30A continuous, a 0.51C rating suited to mixed duty: sustained running with periodic higher demand.

Charging at 30A brings it to full in roughly 2.5 hours. The operating window is -20~75°C on discharge and 0~45°C on charge. The pack measures 210 x 168 x 305 mm and weighs 21 kg.

Where it sits in the range

Within our 72V range this sits between the 55Ah and 60Ah builds. If your runtime target is tighter than expected once we model the duty cycle, the 60Ah configuration is the usual next step; if weight or envelope is the binding constraint, the 55Ah build is lighter.

What we customise

We design to the machine: mounting interface, envelope, connector and capacity. Communication over CAN or RS485 covers integration with vehicle controllers, with Bluetooth for local checks and WiFi or 4G available on request.

Common questions

Can it integrate with the vehicle controller?
Yes, over CAN or RS485. Send the protocol specification and we map it.

Can multiple packs run in parallel for larger machines?
Yes, with matched packs and a BMS configured for it. Tell us the target bank size at quotation stage.

Cells, compliance and lead time

Grade A ternary cells, generally specified with UL recognition at cell level. Every pack ships with a UN38.3 test summary and MSDS prepared for air, sea and road transport. Assembly and testing take around 7 working days. Cell supply is what sets the overall schedule: when the cells your design needs are in stock, samples ship in 12–15 working days; when they have to be sourced, allow 20–25. Tell us your target date early and we will confirm cell availability before you commit to it. Production runs 30–35 working days. There is no minimum order quantity — this is a custom design business and we quote single units, with pricing improving noticeably from 100 packs upward. Ternary lithium warranty typically runs 2 years.
