UFOPOWER engineers custom lithium battery packs for drills, saws, grinders, wrenches and other cordless power tools. UFOPOWER lithium-ion packs deliver higher energy density, longer runtime, faster charging and stable power under load — a drop-in upgrade from bulky Ni-MH packs that keeps your tools running all day, across common 12V, 18V, 20V, 24V, 36V and 40V platforms.
Switching your cordless tools from Ni-MH to UFOPOWER lithium changes how much power you carry, how long it lasts and how often you replace packs — without the bulk.
● High Energy Density: Lithium packs are compact and lightweight, yet store a large amount of energy — ideal for portable power tools where size and weight matter.
● Long Lifespan: Packs maintain high capacity even after many charge-discharge cycles, reducing replacement frequency and long-term costs.
● Power Longer: Long-lasting lithium keeps tools running longer on a single charge — more work per pack, fewer interruptions.
● Low Self-Discharge: Batteries retain most of their charge during storage, so tools are ready to go even after sitting on the shelf for weeks.
● Custom-Engineered Power Systems: From cell selection and custom BMS firmware to housing design and precision welding, UFOPOWER controls the whole process — eliminating compatibility issues and accelerating your time-to-market.
● Certified & Safe: Packs are certified to UL (USA), EN50604 (Europe), NSW (Australia), PSE (Japan) and KC (Korea) standards for safe use worldwide.
UFOPOWER lithium battery packs are engineered for every kind of cordless tool — from fastening and cutting to grinding and sanding.
● Drills & Wrenches: Drills and impact wrenches demand instant high torque — UFOPOWER packs hold steady voltage under load, so every screw drives home at full power and every bolt breaks loose.
● Saws & Cutters: Circular, reciprocating and jig saws draw sustained high power — lithium's stable output keeps blades spinning at full speed from the first cut to the last.
● Grinders & Sanders: Angle grinders need high discharge rates for constant RPM — UFOPOWER lithium delivers the burst energy grinders demand without sag or overheating.
Every cordless tool has its own power profile — torque bursts for fastening, sustained output for cutting, high discharge for grinding. We have categorized our electric tool battery range into three configurations to help you select the right lithium pack for your tool family.
Drilling and fastening is all about torque on demand. UFOPOWER lithium packs deliver the instant high current drills, impact drivers and wrenches need, with stable voltage that holds until the pack is empty — no slowdown when the screw gets tough. And without the Ni-MH memory effect, you can top up anytime.
● Instant high-torque delivery with no voltage sag
● Longer runtime per charge — work all day on one pack
● No memory effect — recharge anytime, anywhere
● Drop-in replacement for existing Ni-MH packs

Cutting tools run hot and run long. Circular saws, reciprocating saws and jig saws demand sustained high-power output, which is exactly where lithium excels. UFOPOWER packs keep the motor at full speed through continuous cuts, run cooler under load, and recharge fast so downtime between jobs stays short.
● Sustained high-power output for continuous cutting
● Fast charging gets you back to work sooner
● Cooler operation under heavy load
● Long cycle life for daily professional use

Grinding and sanding punish batteries with high discharge rates and constant vibration. UFOPOWER lithium packs are built for it: high-rate cells keep the disc at constant RPM, stable power holds right to the end of the charge, and the lightweight design improves tool ergonomics for long sessions.
● High discharge rate for constant RPM
● Stable power output until empty
● Compact & lightweight for better ergonomics
● Low self-discharge between shifts

| Tool Category | Power Demand | UFOPOWER Lithium Advantage |
|---|---|---|
| Drills & Wrenches | Instant high torque | Stable voltage under load, no memory effect, drop-in for Ni-MH |
| Saws & Cutters | Sustained high power | Steady output to empty, cooler operation, fast charging |
| Grinders & Sanders | High discharge rate | Constant RPM, stable power to empty, lightweight |
| Ni-MH Tool Replacement | Drop-in upgrade | Higher energy density, longer runtime, fast charging, no memory effect |
UFOPOWER lithium packs beat Ni-MH on every metric — higher energy density, longer runtime per charge, faster charging, stable power under load, no memory effect and low self-discharge — while weighing less and needing no maintenance. We support common 12V, 18V, 20V, 24V, 36V and 40V cordless tool platforms, with capacities customized to your runtime, power output, tool size and weight requirements. Using Grade-A cells and certified components, UFOPOWER tool batteries deliver a cycle life of 800–1,000 charges, and every pack integrates a smart BMS guarding against overcharge, over-discharge, overcurrent, overload, overheating and short circuit, with flame-retardant housing materials for tough working environments.
