BAK 32140 3.2V 15Ah LiFePO4 Power Battery – 45A High-Discharge, 3000+ Cycles & Stainless Steel Safety Design for Power Tools & E-Scooters (6-Pack)
Description
Product Description:
The BAK 32140 is a professional-grade 32140 lithium iron phosphate (LiFePO4) power battery engineered for extreme durability and high-energy output. This 6-pack bundle delivers a massive 15Ah (15000mAh) capacity and a powerful 3C (45A) continuous discharge current. With an ultra-low internal resistance of just ≤3mΩ, it ensures minimal heat generation and maximum energy efficiency even under heavy, sustained loads.
Built with a reinforced stainless steel casing and an integrated reinforced explosion-proof valve, this cell offers advanced heat dissipation and rapid gas exhaust in extreme conditions, completely preventing swelling or rupture. The advanced LiFePO4 chemistry supports an industry-leading 3000+ cycle life, far exceeding standard lithium batteries. With 6 cells included, you have the perfect foundation for assembling high-performance battery packs for power tools, e-scooters, robotic vacuums, and portable energy storage.

Frequently Asked Questions (FAQ):
Q1: What is the advantage of the 3000+ cycle life?
A1: A 3000+ cycle life means this battery can be fully charged and discharged over 3000 times while still retaining 80% of its capacity. This is significantly higher than standard batteries (typically 500-800 cycles), providing exceptional long-term value and drastically reducing replacement costs over its lifespan.
Q2: What is the 45A discharge current used for?
A2: The 45A (3C) discharge current is designed for high-drain power applications such as electric chainsaws, heavy-duty power drills, and electric scooters. It ensures the battery can deliver sustained high power without voltage sag or overheating.
Q3: How does the explosion-proof safety design work?
A3: The battery features a high-strength stainless steel casing with a reinforced explosion-proof valve and heat dissipation vents. In the rare event of an internal short circuit or pressure buildup, the vents rapidly exhaust internal gases, preventing swelling or rupture.
Q4: Is this battery safe to use in my electric two-wheeler?
A4: Absolutely. With a 15Ah capacity and a 45A continuous discharge rating, the BAK 32140 is an excellent and reliable choice for electric scooters and light electric vehicles. Always ensure your BMS (Battery Management System) is properly configured for 3.2V LiFePO4 cells.
Q5: What kind of charger should I use for this battery?
A5: You must use a charger specifically designed for 3.2V LiFePO4 batteries with a 3.65V cut-off voltage. Do not use a standard 3.7V/4.2V Li-ion charger, as it will overcharge and damage the battery.
