Sandy,
I've kept the Ripmax ESC for future when I understand what I'm doing!
The flashing on the Powertech battery charger LED means that it's gone into trickle charge mode.

It was possibly a Powertech box where I read that the flashing LED indicates charging rather than trickle.Internet search suggests otherwise.I won't be able to look at the same box until Sunday.
Why not post a specific question to owners of said chargers.
If you have a multimeter you can measure the charge rate and the voltage when it switches to trickle.
I am more familiar with Yuasa and leisure battery chargers.
Correctly matched to the battery capacity,these bulk charge at the c/5 rate and switch to a "float voltage" at c/33 rate.
They have a voltage and a current limit and the charge cycle for a 10 amp hour battery on a charger recommended for it would go like this:-
The 2 amp current limit is in operation for maybe 30 minutes and the output voltage reflects the battery state.
While charging at 2 amp,the voltage rises up to the regulated voltage limit (14.5 or 7.3 volts).
The battery charges at 14.5 or 7.3 volts until the current falls to the trigger level of c/33 at which point the voltage steps down to 14.1 or 7 volts which will not damage a battery left on standby.
Your charger outputs a maximum of .5 amps
That is down to economics of supplying stuff from Asia at £3 each.
Charging is possibly 80% efficient so you would need to charge a flat 4.5 amp hour battery for 10 hours at .5 amps.
