12V 100Ah Lithium Battery Pack for Sprayer Trolley and Electric Equipment with BMS

This 12V lithium battery pack delivers a robust 100Ah capacity using high-quality 18650 cells, making it a practical power source for sprayer trolleys, electric vehicles, and other portable equipment. Compared to traditional lead-acid batteries, it offers a lighter weight and compact design without sacrificing energy storage. The integrated Battery Management System (BMS) ensures safe operation by guarding against common electrical faults, so you can rely on consistent power during work. Whether you are running a garden sprayer, a small electric cart, or similar gear, this pack provides the energy needed to get through tasks without frequent recharging interruptions.

Features and Construction

The battery pack is built with a specific cell arrangement and protective circuitry to support demanding applications. Its construction prioritises both capacity and safety, making it suitable for repeated use in various conditions.

Cell Configuration and Capacity

The pack uses 18650 lithium-ion cells configured in a 3s6p arrangement, delivering a nominal voltage of 12V and a rated capacity of 100Ah. Each cell operates at 3.7V, and the combined output provides a continuous discharge current of 20A, equivalent to about 200W. This setup balances energy density with power delivery, allowing the battery to run equipment efficiently.

BMS and Protection Features

A built-in Battery Management System (BMS) provides internal protection against overload, over discharge, over current, and short circuits. This means the battery automatically manages its electrical limits, reducing the risk of damage from misuse or sudden power spikes. The protection circuit helps extend the usable life of the pack by preventing conditions that stress the cells.

Size and Weight

Measuring 150 x 65 x 95 mm and weighing approximately 1050g, this battery pack is compact and lightweight for its capacity. Its small footprint makes it easy to fit into sprayer trolleys, electric carts, or other equipment where space is limited, without adding significant bulk to the device.

Usage and Charging

The battery is designed for straightforward integration into compatible devices, with clear charging parameters to maintain performance. Proper charging habits help preserve capacity over time.

Charging Specifications

Input charging voltage is 12.6V, with a choice of standard 3A charging current or fast 5A charging current. The recommended charging temperature range is 0°C to 45°C, ensuring safe and efficient energy replenishment. Using the appropriate charger (available as an option) will help maintain the battery's health.

Operating Temperature Range

The battery can discharge at temperatures from -20°C to 60°C, making it usable in a variety of climates and seasonal conditions. Storage temperature should be between -20°C and 45°C to avoid degrading the cells when not in active use.

Benefits and Buying Value

This lithium battery pack offers practical advantages for users who need reliable portable power. Its combination of capacity, safety features, and manageable size make it a sensible choice for repeated daily use.

Reliable Power for Work Equipment

With a 100Ah capacity and steady 12V output, the pack can power sprayer trolleys, small electric vehicles, and similar equipment for extended periods. The 20A continuous discharge capability supports moderate loads without voltage drop, helping you complete tasks without interruption.

Safety and Low Maintenance

The integrated BMS reduces the need for constant monitoring by automatically handling protection functions. Lithium-ion chemistry generally requires less maintenance than lead-acid batteries, with no need to check water levels or clean terminals, saving time and effort.

Overall, this battery pack provides a straightforward power solution for those needing a portable, rechargeable 12V source with a generous capacity. Its compact dimensions and built-in protections make it a practical upgrade for existing equipment or a reliable replacement for older battery systems.
