    Power System Sport Plus w/IGN

    I have a Power System Sport Plus w/IGN which I bought a few years ago but have never used yet.
    I want to use it on my GB Yak 54 50 cc airplane with a 14 channel Futaba FASST reciever (R6014HS). The Dealer where I bought it suggests 5-Cell NiCD/NiMH or 2-cell A123 or 2-cell Li-Ion.
    1. Is it okay to use a 5 cell NiMH? The manual for your product suggests that one should not use NiMH batteries.
    2. Can you describe a suitable 2 cell A123 (voltage, mAH, etc)?
    3. Can you describe a suitabler 2 cell Li-Ion (voltage, mAH, etc)?

    Should I always use two batteries, or will one be sufficient?

    Thank you

    RE: Power System Sport Plus w/IGN

    Hi,
    See below.
    ORIGINAL: rmyhara

    I have a Power System Sport Plus w/IGN which I bought a few years ago but have never used yet.
    I want to use it on my GB Yak 54 50 cc airplane with a 14 channel Futaba FASST reciever (R6014HS). The Dealer where I bought it suggests 5-Cell NiCD/NiMH or 2-cell A123 or 2-cell Li-Ion.
    1. Is it okay to use a 5 cell NiMH? The manual for your product suggests that one should not use NiMH batteries.
    This unit is really designed for A123 or 2S Li-ion/poly as there needs to be about 0.5V difference between the input and the 6.0V output.

    2. Can you describe a suitable 2 cell A123 (voltage, mAH, etc)?
    These need to be 2S (commonly called 6.6V). They can be any mAH. You can use real A123s which only come in 2300mAH cells, or you can use generic LiFe batteries.

    3. Can you describe a suitable 2 cell Li-Ion (voltage, mAH, etc)?
    These should be 2S (commonly called 7.4V). They can be Li-ion or Li-poly (if you use Li-poly we HIGHLY suggest you take the batteries out of the plane and charge them safely under observation). Li-ion commonly come in 2600mAH cells.

    Should I always use two batteries, or will one be sufficient?
    You should use two batteries both for current capacity and for redundancy (safety).

    Thank you
