Spektrum s120

[Grum7630]

Hi,
I have been trying to charge Spektrum smart batteries with a Spektrum smart charger.
There is a white light before plugging in the battery which starts flashing purple (two flashes) but then alternates between solid white and flashing purple. I have tried two of my 850mah batteries and different power supplies but always get the same result, I leave the batteries on charge for hours but they don’t charge!

Are you plugging in the balance lead from the battery into the charger?

It’s the smart battery that does not need the balance, Spektrum.

with my spektrum smart batteries i just plug in the balance lead anyway to ensure a good charge.
i would give that a try and see if it does anything.

The batteries don’t have balance leads though.

The S120 requires a balance plug from a 2S, or 3S Spektrum Smart battery to work properly. (Edit: Except when charging 6/7 cell NiMH)

There are no balance leads on the batteries.

The S120 will not charge that battery.

It’s sold as a kit

You are correct. It is sold as a kit. That G2 battery uses a single 3-wire charge/balance plug, and it SHOULD charge.

It may be below the minimum voltage to be recognized by the charger. Do you have a cell checker so you can check each cell voltage?

I have found no information about what the purple/white LED code is, yet.
White, on.
1 purple, under 25%.
2 purple, 25%-75%.
3 purple, 76%-99%.
Green, full.
Red, error.

You do need a usb charger block that supplies 20 watts, or more.

EDIT: It's possible that it needs an update.
Normally, a Red/Green/Blue LED code means it needs an update, but you can check here ---> Smart Charger Updates

It needed an update. All working now
