2.0Ah for starter kits, 4.0Ah for mainstream tools and 5.0Ah for longer runtime or higher-load cordless programs.

Professional Cordless Battery & Charger Manufacturer
VoltForge supplies 20V and 40V lithium battery and charger systems with 2.0Ah, 4.0Ah and 5.0Ah packs, standard or rapid charger options, UN38.3/MSDS transport document routes and MOQ from 800 units. The battery system is the repeat-purchase engine behind a cordless tool range, so capacity, charger, cell route, packaging and shipping paperwork must be selected together.
A Cordless Battery & Charger System range your customers will understand.
The battery and charger shape the way a whole cordless range performs, ships and sells. A larger pack adds runtime, but it also changes weight, shelf price and freight cost. We help you select the pack, charger plug, cell route, carton label and transport documents that fit your tools, target market and replenishment plan. The goal is a battery system that customers can understand and distributors can keep selling after the first kit.

A different range for every sales channel.
Retailers, distributors and trade buyers often need different voltage, packaging and price positions. We can match the build to the way you sell.
Starter retail kit
Use 2.0Ah with a standard charger when compact weight and entry price matter more than extended runtime.
Mainstream 20V platform
Use 4.0Ah as the shared working pack across drill, driver and selected grinder kits.
Trade and grinder program
Use 5.0Ah with a suitable charger when runtime and performance continuity are part of the sales promise.
Compare popular configurations.
Use these examples as a starting point. We can fine-tune the final configuration for your product range and market.
| Platform / range | Type | Key characteristic | Typical use |
|---|---|---|---|
| 2.0Ah | Starter lithium pack | Lower weight and lower kit cost | Compact drill/driver, entry retail and promotional kit |
| 4.0Ah | Mainstream lithium pack | Balanced runtime, weight and shared-platform appeal | 20V distributors, hardware retail and bundle programs |
| 5.0Ah | Trade lithium pack | Longer runtime and stronger performance perception | Brushless drill, grinder and installer channels |
| 40V 4.0Ah / 5.0Ah | Higher-output power system | Separate high-output platform logic | Heavier cordless range and contractor programs |
Not sure where to start? For a first 20V private-label range, begin with 2.0Ah in the entry drill/driver kit and 4.0Ah as the core replenishment pack. Add 5.0Ah only when the product mix includes brushless or grinder applications that genuinely need it. We will review the final selection against the intended work, destination market and approved sample.

Common questions, answered.
Need something else? Our engineering and sales teams can review it with you.
Product specifications & engineering
Is 5.0Ah always better than 4.0Ah?
No. A 5.0Ah pack increases runtime but adds weight and cost. It is most useful for brushless tools, grinders and higher-duty users rather than every retail starter kit.
Can one 20V battery fit every tool?
It should fit every tool within the defined platform, but performance varies by load. Use the same pack family while matching capacity to the tool and expected user time.
What should be checked on the charger?
Confirm input voltage, plug, charge time, label language, thermal behavior, tool compatibility and the safety/document route for the destination market.
Which transport documents apply?
Lithium packs typically require UN38.3 and MSDS-related information. The exact document set and carton marking depend on the pack and shipping method.
Customization & commercial terms
What is the battery MOQ?
Standard 20V packs normally start at about 800 units. Special cell routes, private label, rapid charging or dedicated packaging generally require higher quantities.
Can we buy batteries as replenishment SKUs?
Yes. A replenishment pack needs clear compatibility, capacity, label and carton logic so distributors can sell it after the original tool kit.
How long do samples take?
Standard battery and charger samples usually take 12-20 days. Plug, label, document or cell-route changes can extend the route to 20-30 days.
Can the charger plug be changed by market?
Yes, but plug type, input label, charger safety scope and packaging need to be confirmed before the final sample and production release.

Sourcing Cordless Battery & Charger System: what to check before you order.
01Choosing the Right Cordless Battery & Charger System
The best cordless battery and charger system depends on where and how you plan to sell it. Start with the user, your target price and the role it will play in the range. We can then match the platform, performance level, battery or accessory route, packaging and test plan. With those details agreed, you can compare quotations on the same basis and avoid a sample that looks good on paper but does not suit the final program.
02Choose Your Voltage Platform First
Price is easier to judge once the platform is clear. A lower-voltage model can be the right choice for a price-led retail line, while a shared 20V platform gives distributors more room to add tools and replacement batteries later. Higher-output programs work best when there is a real need for more runtime or heavier work. Tell us about the customer, sales channel and expected shelf position, and we will help you choose the balance of performance, battery cost, carton weight and future range expansion.
03Focus on the Specs That Affect Performance
For cordless battery and charger system, the important figures are the ones that affect the job: torque, output, capacity, disc size, tool mix or charging route. Ask how each figure is measured, which components support it and how the tool performs with the recommended battery, accessory or load. A useful specification includes the working condition as well as the target number. That gives our engineering team something clear to verify during sampling.
04Prepare Documents for Your Market
A product is ready for market when the selected configuration, charger, battery, label, manual, carton and document route all match the destination. CE, EMC, RoHS, UN38.3, MSDS, charger safety and carton marks need to apply to the actual product and shipping method. Share your market and logistics route at the start. We can prepare the right document checklist while the sample is being made, rather than reopening the project after the packaging has been approved.
05How We Check Quality
Each quality check protects a different part of the order. Incoming components, critical assembly, functional testing, load or charge behavior and final pack-out all matter. We can share the relevant inspection method or record for your configuration: fixture checks, meters, load benches, AQL lists, traceability labels or document review. Tell us which product claims matter most to your customers and we will include them in the inspection plan.
06What Affects Price and Lead Time
The main cost drivers are platform choice, motor or cell route, battery capacity, performance hardware, case or color box, print complexity, custom color, order quantity and required documents. Timing changes when any of these items changes after the sample is approved. For a smoother launch, confirm the product configuration, artwork, pack-out and market document checklist together. We will then map the sample, production, inspection and shipment stages for your order.
07Compare Options for Your Product Range
There is rarely one model that suits every customer. A smaller or entry configuration may be better for shelf price and carton weight. A brushless, higher-capacity or shared-platform option may give your range stronger runtime and a clearer upgrade story. Start with the option that fits your most common customer and price band, then keep a defined upgrade for higher-demand users. We can help you build that good, better and best structure.
08Before You Approve Production
Before mass production begins, review the approved sample against the final order: configuration, key performance target, battery, charger or accessory route, logo, color, case or box, manual, labels, carton marks, destination documents, quantity and delivery date. We can provide final pack-out photos and a summary of the outgoing inspection plan. For higher-risk products, you can also request the relevant functional record or sample report before shipment.
