Why Quality Matters: The ASOL Difference
Not all lithium battery packs are created equal. Here’s what sets ASOL apart:
- Factory-Tested Every Unit - Every pack undergoes individual capacity, voltage, and internal resistance testing before shipping
- Consistent Cell Matching - Cells are matched within ±0.05V for predictable, stable performance across all 6 series cells
- Professional BMS Integration - Built-in Battery Management System ensures balanced charging and discharging
- UN38.3 Certified - Safety tested and certified for international shipping
Runtime Considerations
Actual runtime depends on motor and pump load, cleaning mode, duty cycle and system efficiency.
Cycle Life Explained
A “cycle” equals one full discharge followed by a full recharge. The ASOL 6S1P maintains ≥80% capacity after 500 cycles under standard test conditions (0.2C discharge, 0.5C charge at 25°C).
Partial charging affects cycle consumption differently from a full depth-of-discharge cycle. Actual service life depends on depth of discharge, charging practice, temperature, device load and operating conditions.

Frequently Asked Questions
Is this battery compatible with my floor cleaner model?
Compatibility must be verified against the target device requirements, including nominal and charging voltage, continuous and peak current, polarity, connector and pinout, physical dimensions, charging system, protection or BMS requirements, and any communication requirements.
How many times can I recharge this battery?
This battery is rated for 500+ full charge cycles while retaining at least 80% of its original capacity. Actual service life depends on depth of discharge, charging practice, temperature, device load and operating conditions.
Is this battery safe to use in home cleaning devices?
Existing UN38.3, CE and RoHS documentation is available for the selected configuration; MSDS safety documentation can be provided for project review. The battery features built-in over-charge, over-discharge, over-current, short-circuit, and over-temperature protection.
How are evaluation requirements handled?
Sample evaluation may be available for selected cylindrical and lithium polymer battery projects, subject to specification review and product availability. Sample freight is paid by the customer. Include any evaluation requirements in Additional Requirements.
Do you offer international shipping?
Shipping arrangements, costs and lead times are confirmed according to destination and project requirements.
What is the difference between 6S1P and other configurations?
6S1P means 6 cells connected in series (6S) with 1 parallel group (1P). This configuration delivers 21.6V nominal voltage - ideal for high-power floor washer motors and water pumps. It provides significantly more power than lower-voltage configurations while maintaining a compact size.
