Evolution battery drain

  • I have an evolution in my Spitfire, it is powered from 2 of the power box 2800 batteries, Usually I will fly 2 or 3 (8 - 10 min) flights in a day, when I charge the system the for the next days flying, one battery will charge in less than 1 hr, the second battery will take up to 2.5 to 3 hrs to reach full charge, is this normal? I was under the impression both batteries should be draining at approximately the same rate.Please advise if you think there is a problem, I have changed out both batteries with new ones and still the same situation occurs, always on the same power input (voltage regulator?)

  • Thank you Richard,
    I will remove the evolution unit and send to you folks for a check up, If I send the 2- 2800 batteries with the unit, can you also confirm they are ok? These units are the old style have only the 2 wire remote LED. I would be happy to pay an extra charge to replace these batteries with the new style if you folks are willing to do this please advise.

    Thank you in advance,
