High Voltage Hybrid Battery Chargers

                           (for professionals only - we cannot sell to individuals)


**Please Note: 

To order, please contact Claude Phipps (crphipps@aol.com). We have now shipped nearly 40 units.

Our specialty is custom charger units. Contact us for details!


Our most popular is the QDHC-350A, which has 2A and 6A charge currents, selectable with a front panel switch.

For reconditioning batteries, you might want the model QDHC-350A combined with the QDD-100 discharger.

We ship internationally, usually for less than $175. Within the U.S., shipping costs are about $100.

For most sales, we must insist on PayPal. We cannot sell to private individuals, only professionals.



We designed and developed an outstanding line of industrial quality high voltage hybrid battery chargers and dischargers. These share a unique design without transformers or other heavy, power consuming devices.
Typical weight for standard units is 7 pounds.
The control board switches input power
directly into your battery and stops the charge at a level which you
set. We have an excellent reputation with our customers - and you should have one for your shop!

Five Levels of Safety in the Design

Comments from Users:

"These are wonderful pieces of machinery. I can tell that you put great care into the design and build of each one! ....
It has been working phenomenally. I couldn't have asked for a better charger."
- Max Pfeiffer, University of Washington Hyperloop Project


"I don't want to buy something from somewhere else now that I have been spoiled by your charger. I don't see any other

chargers for sale that are quality pieces of equipment. I believe in your product."

- Charles Ware, Huntsville Hybrids

Note 2: What you save with a hybrid automobile: 25 kWh from your wallplug costs $2.50. Let's say you drive your
SUV an hour a day. A typical SUV cruising at 60 mph uses 36 hp (25kW) in steady driving. In an hour, that's 25kWh.
Its mileage is 20 mpg. In an hour, it has gone 60 miles, and used 3 gallons of fuel. A gallon costs $2.10, so that hour
cost $6.30 in gas. If it were charging a hybrid instead, at 80% efficiency, you would have saved $3.80/day, $115 a month.
Is that convincing?
