Product Overview

Dual Pro Recreation Series (RS3) 6Ah x 3 bank Battery Charger

This charger is a great tool for competition robotics teams and hobbyists using Lead Acid batteries. Dual Pro chargers charge batteries to 100% specific gravity every charge, and are able to adjust current in the absorption and finish stages based on the battery's communication with the charger

There are three (3) unique charging banks included in this charger, meaning that you can charge three batteries at a time. Each bank has a capacity of 6 amps. This charger supplies a safe amperage level to quickly charge 12V lead acid batteries. The charger is engineered for occasions which need a charging system that may require the battery to be left on the charger for days at a time.

We have installed SB-50A connectors on each of the three charging circuits, which make this charger ready for robot batteries.

Features
  • Dependable, rugged construction and waterproof
  • Independent outputs and fully automatic
  • Battery maintenance mode
  • DC charge cables = 5ft and AC power cord = 3ft
  • Each DC charge cable is fitted with an APP SB-50A connector (3 total)
  • Approved and meets ISO 8846 Marine standards
  • Models available to charge 12-36V systems

Troubleshooting & Warranty:

Dual Pro Uses Deltavolt Intuitive Charging Technology

These chargers are on the cutting edge of technology. Dual Pro chargers can detect as low as 6 volts on a 36 volt system and 8 volts on a 48 volt system. Low voltage detection eliminates jump starting and service calls which save you time and money.

Dual Pro goes beyond what normal chargers do. Normally your average charger only charges your battery until it gets warm enough and your battery tells your charger that it's done. That is not the case for Dual Pro, they acknowledge this and also know that most batteries only get 80% of their full charge from ordinary chargers.

The DeltaVolt charge profile changes that. By giving you a full 100% charge, your batteries runtime will increasing by 10-15% per charge which will increase your overall battery life by 20-25%. Pay a little bit more now for your charger and save a lot more money with longer battery lives and having no more service calls.

Why choose Dual Pro?
  • It's the only 5 stage charger on the market
  • Recovers 100% DOD batteries to 100% charge
  • Charges to recommend specific gravity
  • LED charge status light with fault detection
  • Equipped with reverse polarity protection
  • Includes zero spark technology
  • Fully repairable charger

    Working with AndyMark is like working with your family (the part of your family you like, though :-). We had a little shipping problem in the busy part of the season, and they got to the bottom things right away with a personal touch.

    wired incorrectly

    2 out of 3 connectors were wired improperly. We had to cut their connectors off and rewire them to get it to charge batteries. We would have returned it but got it just in time for regional and needed it. Otherwise charged nicely (AndyMark response: We apologize for the issue, we have contacted and worked out the problems.)

    Watch your power bar

    This is a wonderful charger, but remember that most power bars are rated for 15 amps and this runs at 18 amps so it needs to be plugged directly to the socket.

    great placement of indicators so when placed on a cart were easy to see...leads sufficiently long enough to run through cart to slots holding batts on charge...floating charge is perfect

    3 Bank Battery Charger.

    Fully Potted, gets warm, but seems to be designed to handle it. We put two on our battery cart. Seems much more robust then the $40 chargers, we have been buying and replacing for the last 3 years. Hopefully these hold up and the charger woes are over.
