Product Overview

This battery management system is designed for specific applications, ensuring optimal performance and safety. It is crucial to adhere to the guidelines provided to prevent damage and ensure longevity.

Key Features

• Cautionary Use:

– Not suitable for lithium iron phosphate batteries, hernia lamps, hand drill battery packs.
– Incompatible with electric fishing machine batteries, electric bicycle batteries, children’s car batteries, motors exceeding 550 power types, and 1W fish-eye LED lights.

• Applicable Products:

– Ideal for massager battery packs, LED lamp backup power systems, various 12V electronic devices, solar street lamp battery packs, monitoring backup power solutions.

• Discharge Specifications:

– Supports products with a discharge current of up to 3A; the discharge rate must exceed 3C.

• Temperature Management:

– The battery may heat up during use if the multiplier is not appropriate; prolonged use under these conditions can lead to rapid damage.

• Wiring Instructions:

– Follow strict wiring diagrams:
– Connect as follows:
– B- (0V), B1 (3.7V), B2 (7.4V), B3 (11.1V), B4 (14.8V), B+ (18.5V).
– Avoid intentional short-circuiting.

• Charging Protocol:

– Ensure charging occurs after connecting wires; output will only be available post-charging.

• Battery Grouping Guidelines:

– When connecting five groups of batteries in series, ensure each group has identical voltage levels.
If discrepancies exist in voltage levels among groups or if any group shows rapid voltage drop during testing—indicate poor quality batteries.

• Battery Mixing Warning:

– Do not mix good and bad batteries together; uniformity in capacity/internal resistance across all five groups enhances performance (e.g., combining three good with two bad results in overall poor performance).
