Detailed Product Description

Protect and manage your custom lithium battery pack with the DALY 13S 48V 60A Battery Management System, designed for 13-series lithium-ion battery packs using 3.7V 18650 cells. This BMS is ideal for building or repairing 48V nominal battery packs used in electric bicycles, scooters, solar backup packs, DIY power banks, and other lithium battery applications.

The unit helps monitor and protect your battery pack from common electrical risks such as overcharge, over-discharge, overcurrent, short circuit, and cell imbalance. By managing charging and discharging safely, the BMS helps extend battery life and improve the reliability of your lithium battery system.

This 13S configuration is suitable for lithium-ion packs with a nominal voltage of 48V and a full charge voltage of approximately 54.6V. It is compatible with standard 3.7V Li-ion cells, including popular 18650 cylindrical cells, when arranged in a 13-series battery pack.

Why Choose This BMS?

A lithium battery pack should never be used without proper protection. The DALY 13S 60A BMS acts as the safety control board between your battery cells, charger, and load. It helps prevent unsafe voltage levels, protects the battery during high-current use, and improves overall pack stability.

This BMS is especially suitable for 48V e-bike battery builds, including packs made from 18650 cells in configurations such as 13S4P, 13S5P, 13S6P, 13S7P, 13S8P, or larger, depending on the capacity and current rating of the cells used.

Suitable For

• 48V electric bicycle battery packs
• 48V electric scooter battery packs
• DIY 18650 lithium battery builds
• Lithium battery repairs and replacements
• Solar and backup lithium battery projects
• Portable high-capacity power packs

Important Note

This BMS is for 13S lithium-ion battery packs only. It is not suitable for LiFePO4 battery packs unless specifically stated by the manufacturer. Always confirm your battery cell type, wiring sequence, and charger voltage before installation. For 13S Li-ion packs, use a 54.6V lithium-ion charger.
