The Speedotrack72V 30Ah portable battery pack is a compact, safe and economical lithium-ion battery pack. This standalone battery pack was designed for electric scooters, with high-power NMC lithium-ion cells. No additional equipment is needed for the safe operation of this battery pack. In extreme operating conditions, the integrated BMS disconnects the battery from the system. This ensures safe operation and protects the battery pack against short circuits, over-charge, over discharge, over current, over temperature and under temperature events.
The integrated BMS passively balances the charge between all cells in the battery pack. Energy is discharged from the cells with the highest charge in the pack, which maximizes the runtime of the battery pack and extends its life. This lithium-ion battery pack is maintenance free, and has a longer run time with a shorter recovery time than equivalent lead acid battery packs. It weighs 70% less and takes up 60% less space than equivalent lead acid battery packs, providing increased range and product compatibility.Please get in touch and our expert team will contact you.

Speedotrack Li-ion Battery operation
Mode of Operation
The Speedotrack72V 30Ah portable battery pack has two modes of operation: Active mode and Low power mode. In active mode all BMS monitoring operates normally. Active mode is entered automatically when battery use is detected. Low power mode maintains all battery and safety protections, but with a reduced measurement frequency.
Discharging
The Speedotrack72V 30Ah portable battery pack can provide up to 40 A of Continuous Current though the Battery Management System (BMS). Speedotrack Battery Management System is rated for 60A (Max) Continuous Output so that battery can be used up to where more than 40 A output required.
Charging
The Speedotrack 72V 30Ah portable battery pack should only be charged with approved chargers. Charging with a 5 A charger will result in a slightly longer battery lifetime, but our battery is compatible with up to 15 A charging for convenience. The battery pack is compatible with charging from regenerative braking technology.
Passive Cell Balancing
The integrated BMS provides passive balancing of up to 85 mA. Cell balancing is achieved by discharging energy from the highest charged cells, resulting in increased pack lifetime with a higher capacity and longer runtime than unbalanced battery packs.
Primary Fault Protection
The integrated BMS monitors the battery to ensure safe operation. It is connected in series to the negative line of the battery. it provides protection against Cell Under-Voltage and Over-Voltage, Low and High Temperature, Short circuit etc. The cell thresholds are configured according to the lithium-ion cell.
Secondary Fault Protection
The Speedotrack 72V 30Ah portable battery provide solid fault protection. The integrated Battery Management System (BMS) will permanently disconnect the battery pack from the system if the primary protection system is compromised, ensuring battery pack safety.
Typical Application
The Speedotrack 72V 30Ah portable battery pack is typically used in Electric Scooters, Backup Power Systems and other portable power applications. The following is an example of a Speedotrack 72V 30Ah portable battery pack used in a 72 V electric scooter with a charger. Please get in touch and our expert team will contact you.
