Product Description

High Safety Low Internal Resistance 32140FS V3.0 Lithium Iron Phosphate Cell 15Ah 3.2V High Rate Long Cycle Power Storage Battery Cell

High Safety Long Cycle 32140FS(V3.0) 15Ah 3.2V Lithium Iron Phosphate Power Battery Cell For AGV Light Vehicle Portable Energy Storage

Product Specification & Core Features

This 32140FS(V3.0) unit belongs to the mature 32 lithium iron series with flat full tab and groove sealing craft, delivering stable consistent performance in mass production. It carries 15Ah nominal capacity and 3.2V nominal voltage with lithium iron phosphate cathode material, reaching 163Wh/kg energy density while internal resistance controlled below 1.8mΩ.

It supports flexible charge and discharge rates: standard 0.5C charge/discharge, continuous 2C charging, 3C steady discharge and 6C 10-second pulse discharge, with 3.6V charge cut-off and 2V discharge cut-off voltage. Its cycle life varies by current rate, offering over 2500 cycles under low 0.5C/1C load, 1500 cycles at 1C/2C and 800 cycles under heavy 2C/3C operation.

A wide temperature window covers charging from 0℃ to 60℃, discharging from -20℃ to 60℃, and different storage temperature standards for 3-month and 6-month preservation to maintain cell activity long-term.

Application Matching Advantages

This lithium iron phosphate cell is tailor-made for multiple power and energy storage scenarios with outstanding adaptability.

For light electric vehicles, its stable 3C continuous discharge and strong pulse output satisfy instant acceleration power demand without voltage drop
In portable energy storage equipment, the 163Wh/kg high energy density reduces overall product weight while extending standby runtime
As core power batteries for small power equipment, its long cycle lifespan effectively cuts later maintenance and replacement cost
For AGV automated guided vehicles, the wide low-temperature discharge performance (-20℃) ensures stable operation in cold warehouses and factory workshops, and the standardized cell design simplifies battery pack assembly and series-parallel combination design for system manufacturers

Built-In Safety Performance

The cell owns multi-layer safety advantages rooted in material and structural design.

Lithium iron phosphate cathode features ultra-stable crystal structure, which will not decompose or release heat under overcharging, extrusion or high impact, fundamentally avoiding thermal runaway risks
The flat full tab and integrated groove sealing structure prevent electrolyte leakage and short circuit caused by shell deformation
Ultra-low internal resistance below 1.8mΩ greatly reduces heat generation during high-rate charge and discharge, eliminating hidden danger of local overheating
Strict charge and discharge cut-off voltage limits avoid overcharge and deep over-damage
The wide operating temperature range prevents performance attenuation and safety hazards under extreme high and low temperature working environments, passing rigorous high-rate pulse and cycle aging safety verification

Frequently Asked Questions

Q1: What is the longest service life of this battery cell?

A1: It can reach more than 2500 full cycles under 0.5C low current charge and discharge, equivalent to over 7 years of daily normal use.

Q2: Can the cell work normally in cold winter outdoor environment?

A2: Yes, it supports discharge at -20℃, but charging needs to be done above 0℃ to protect internal electrode structure.

Q3: What's the maximum instantaneous output power it can provide?

A3: It supports 6C pulse current lasting 10 seconds, suitable for equipment requiring instantaneous high power output.

Q4: Is this cell reusable after long-term storage?

A4: Within 6 months storage at -10~25℃, the cell retains over 90% capacity and can be activated by standard 0.5C charging normally.

Q5: What industries cannot use this lithium iron phosphate cell?

A5: It is not recommended for ultra-small wearable micro-devices due to its 15Ah large capacity; it is mainly oriented to medium and large power mobile equipment and energy storage products.

We’ve been buying from VATS Battery for over a year now, and they never disappoint. This 10500 3.7V cylindrical lipo is a little powerhouse for our wearable tech line. Zero memory effect, lightweight (around 8g as listed), and the price-to-performance ratio at around $1.20 is unbeatable for Grade A cells. Standard T/T payment was smooth, and lead times are always predictable. Highly recommended for any tech startup or established manufacturer.

Honestly, it’s a solid 10/15! Finding a reliable 10500 cell with a true 10C discharge rate for our custom power tool prototypes was a nightmare until we found VATS. The continuous discharge is super steady, and the capacity is exactly as advertised. What blew me away was their OEM service—we needed custom wiring and specific connectors, and their engineering team nailed it on the first try. If you're looking for custom high-drain lipo packs, these guys are the real deal.

Spot on service from start to finish. I was a bit skeptical about ordering overseas because we needed these 400mAh batteries urgently for a client's smart pen project. But blimey, they arrived in just over a week! They were out of stock initially, but the communication was brilliant, and they shipped them out the moment they were ready. The packaging was top-notch too, very secure. Will definitely be placing a bulk order soon.
