TB47s going red

[licensed pilot]

Looks like my older TB47s are giving up. On take off, all four cells dip to red. (Fully charged) I've deep cycled with the Angel device, no change.

Much appreciated; They are 4-5 years old so I've gotten a lot of flights out of them.

For deep cycling I levae the battery in the inspire until it shuts down by itself. Then I charge the battery with the slow charger (100w). Then fly that battery till 10-15% and again leave in the inspire until it shuts down by itself. It usually takes about 10-15 min for shutdown from 10% battery level. On the next (the third one) charge and flight I have great flying time. Unfortunatelly for very old and heavy used batteries this will not help much but overal is the best reviving practice I've found.
