Manufacturing · Solar & Renewable Energy Equipment
Everyone asks for a battery pack quote and then asks if we can do it for less.
A battery pack enquiry rarely arrives complete. Someone writes 'need 48 volt pack, price?' and nothing more. Cell type, discharge rate, size limit, protection and certification all change the price, and an engineer's afternoon goes on a quote that was never going to convert.
Scope, fee, reporting and term are agreed in writing after we have read your brief and spoken to you.

In one paragraph
Battery pack manufacturing is the assembly of cells, a battery management system, casing and wiring into a pack built to a customer's voltage, capacity and size. GullySales helps pack makers get found by OEMs and product developers, qualify enquiries before engineering time is spent, and follow up each quotation.
The pack maker who wins is the one who asks the right questions early, replies with a clear scope, and stays in touch while the customer finishes their own product.
Last updated 16 Oct 2026. Licence, certification, labelling and advertising rules for solar & renewable energy equipment differ by product and change. We describe them in general terms, so check the current position with your own adviser or the regulator before you publish a claim.
Who it is for
This is written for you if battery packs is what you make or sell.
- Pack assemblers building for e-rickshaws, two-wheelers and light electric vehicles
- Makers of packs for power tools, medical carts and portable equipment
- Assemblers of packs for solar street lights and small storage units
- Contract pack builders working to an OEM's design
Not for
It is not the right fit if.
- Assemblers who cannot say where their cells come from, because buyers will ask
- Firms looking for us to state safety or transport approvals. Those are for your certifying body and your adviser
How buyers choose
What decides the sale of battery packs.
The specification sheet from the buyer
Voltage, capacity, discharge current, charging method and a size envelope. Buyers who cannot supply these are early stage and need a different approach.
Cell source and chemistry
A product developer asks which cells you use, where they come from and what the pack's cycle life is likely to be. Honest, documented answers separate a pack maker from an assembler of anything.
Sample pack and trial run
An order starts with a sample, which the buyer tests on their own product. Staying in touch during that test is where the order is won or lost.
Warranty and field returns
Buyers ask who handles a failed pack in the field. A clear process matters more than a long warranty line.
Where orders are lost
What usually goes wrong when you sell battery packs.
In the words owners use on the first call.
“We quote and the customer disappears”
Many enquiries are from people still designing. A quotation sent too early, with no follow-up date, goes cold before their product is ready.
“Customers compare us with imported packs”
A cheaper pack with a thin spec sheet looks the same in a rate comparison. The buyer needs to see cell source, protection and testing.
“Each enquiry needs an engineer's time”
Without a form that captures the basic specification, your engineer asks the same ten questions on every call.
The scope
The work we would propose for battery packs.
Measured on qualified enquiries, quotation requests, follow-up on each quotation, trial orders won and repeat orders. Anything here that needs a platform, directory or tool we have not used with you is confirmed with you before it goes in the scope.
- A pack specification formA form asking voltage, capacity, discharge current, size limit, quantity and use, so engineering time goes to real enquiries.
- Qualification before quotationA short checklist that separates a developer with a drawing from a person with an idea.
- Sample-stage follow-upA scheduled call while the buyer tests the sample, with notes on what they found.
- Application pages by usePages for e-rickshaw packs, tool packs and street light packs, each written for that buyer's questions.
A cell sourcing and testing note
A plain page stating the cell source, the tests you run in-house and the records you keep.
What we do
What you get for battery packs.
Each deliverable and what it is there to change.
A pack specification form
Collects the details your engineer needs and shortens the first call.
A qualification checklist
Lets a sales person decide in a few minutes whether to start engineering.
An application page for each pack type
Puts your name in front of buyers searching for a pack for their specific product.
A sample trial tracker
Records each sample sent, the buyer's product, the test stage and the next call.
How the result is measured
- Qualified pack enquiries
- Quotation requests with a full specification
- Follow-up on each sample and quotation
- Sample approvals
- Repeat orders
- Enquiries dropped at qualification
Recorded as a baseline before work starts, so every later report has an honest comparison.
How it works
From your first message to the first report.
No open-ended retainer. Every step gives you something in writing.
First
Your brief
You tell us what you need in a few short steps: your business, what you want, where enquiries come from and how they are handled.
After the brief
A conversation and a written scope
We read it, then talk with whoever handles your enquiries. If you want our help, the scope, the fee and the reporting come in writing, and nothing starts before you have read them.
Before work starts
Baseline recorded
The numbers this work is meant to move, such as enquiries, quotations, orders, visits or renewals, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
The fix we agreed to start with is put in place and measured against the baseline, whether that is a reply, a follow-up, a page, a listing or the handover between marketing and sales.
As agreed
Report against the baseline
What moved, what did not, and what changes next, in plain words. How often you get it is set in writing before work starts.
At renewal
Renew on the numbers
The term ends and you decide whether to continue from the results. The length is agreed in writing before anything starts.
What we need from you
What to have ready before we talk.
None of it has to be tidy. We read what you have.
- Packs you have built, with the application for each
- Cell suppliers and chemistries you use
- Enquiries from the last few months and their outcome
- Test procedures and records you keep
- Warranty terms and how field returns are handled
Export and new regions
Selling battery packs beyond your home market.
Where you sell decides standards, documents, payment terms and freight. We work from Bengaluru and have no overseas office, so for a new region we start from your own enquiries, your existing buyers and the directories you already use.
Product makers abroad
Overseas buyers of packs are product makers who need a supplier for one component. They find suppliers through directories and referrals, so existing export contacts come first.
Shipping restrictions
Packs fall under special shipping rules for many carriers and countries. Your freight forwarder and adviser state what applies. The page should say how you ship samples.

Why owners pick GullySales over an agency.
Marketing and sales, as one job
