e-power systems
Advanced power made practical
We turn any vehicle into a self-contained mobile business
Allied's E-Power Shop builds the power system, the workspace, and the vehicle around it — so your crew pulls up, plugs into nothing, and works a full day. No generator. No propane. No idling.

What the E-Power Shop does
Two ways to electrify a work vehicle
Most shops do one or the other. We do both, under one roof, on the same build — because the right answer depends on what your day actually looks like.
Pillar 01
Electrify the work
The engine drives. The batteries work.
A conventional gas or diesel chassis gets you to the site. Once you're parked, a lithium (LiFePO₄) system runs everything you came to do — for a full working day, in silence.
Works on any chassis you already buy and already know how to service. This is the bigger half of our business.
Pillar 02
Electrify the vehicle
Factory EV platforms, upfit properly.
Fleets moving to electric chassis need an upfitter who understands high-voltage systems, payload budgets, and what a body does to real-world range. We build on them every week.
Also a straight answer when an EV chassis is the wrong tool for the route. We'll tell you.
Inside the system
Engineered as one system, not assembled from parts
Anyone can bolt a battery to a wall. The difference is what happens on day 400 — in the rain, in the cold, with a tech who needs to fix it in an hour.
Power sized to the job
We start from your equipment list and your duty cycle, then size the bank, the alternator, the inverter and the charging path to match. Undersized systems are the number one reason mobile businesses go back to generators.
One screen, real control
A 7″ touchscreen shows state of charge, load, water levels and system health at a glance — with waterproof physical buttons for the things you need when your hands are wet.
Protected electronics
A sealed, positive-pressure electronics cabinet. Water, hair, dust and shampoo stay out of the components that cost the most to replace.
Shore power, wired in
A wired-in 30-amp shore inlet with cord and 15-amp adapter. Plug in at the shop, at the house, at the event — no extension cord through a window.
Serviceable by design
Aluminum, stainless and composite construction. QR codes throughout the vehicle link a technician straight to the documentation for the part in front of them.
Built to be lived in
All-season climate control, MERV filtration, sensible lighting, and a layout planned around how the work actually flows — not around where the brackets were easy.
Component specifications current as of August 2026 — confirm details with an Allied specialist before ordering.
e-spa
The flagship build · proof the system works
The mobile grooming van that never idles
The e-spa is where we proved all of it. A complete grooming salon in a high-roof van, with every piece of equipment on battery power — climate, heat, dryers, water, lighting and tools running a full day of appointments without a generator, without propane, and without the engine running.
It's the most demanding mobile business we build for. Water everywhere, high-draw dryers, a groomer who can't afford a downtime day. Everything we learned making that work goes into every other vehicle that leaves this shop.

The E-Power Configurator
Price your build in about five minutes
Pick a platform, tell us what the vehicle has to do, choose your options — and get a real number, plus a request that lands with our team the same day. No phone tag, no waiting a week for an estimate.
Step 01
Choose your platform — Sprinter, ProMaster or Transit high roof
Step 02
Tell us the job — grooming, veterinary, work station or something else
Step 03
Standard package or fully custom — then pick your options
Step 04
Review your estimate and send it to us with one click
Pricing shown in the configurator excludes taxes, local fees and licensing. Vehicle pricing is an estimate and is completed through our preferred dealer.
How a build happens
From first call to keys in hand
Step one
Scope the day
What equipment, how many hours, how many stops, what climate. Everything downstream comes from this conversation — and it's usually 20 minutes.
Step two
Configure & price
Standard package or custom. You can do this yourself in the configurator, or with a specialist. Either way you leave with a number.
Step three
Chassis & build
We complete the build through our preferred dealer so the chassis is sold to you as a new vehicle, with the full package on one invoice. We keep standard units on the ground or already in process.
Step four
Delivery & support
Hands-on orientation, documentation, and a support portal that stays with the vehicle for its whole life.
After delivery
Support that comes with the van
A mobile business that can't work today isn't a business today. Our support is built around getting you back out — not around opening a ticket.
01
Secure owner portal. Documentation, how-to videos, replacement-part ordering and service requests, in one login.
02
QR codes throughout the vehicle. Scan the part in front of you and get its documentation, not a 200-page PDF.
01
Tracked support tickets by phone, text or email — so nothing gets lost in someone's inbox.
01
Remote diagnostics login for technicians, so a lot of problems get solved without a trip.
