Sur Ron Bypass “Recovery” charger for Bypass mod Or Flat battery
To recover a Standard Sur Ron battery that has been drained too far for the OEM Sur Ron charger to work.
This is a lower voltage charger that has ben adapted to plug direct into the discharge port of a Sur Ron standard battery.
Please note, if your battery was drained and then left to sit empty fo a longer time (three weeks or more) it may stil fail to charger.
How to use.
If your battery has been left in the outside cold, please bring into a warm heated place and allow to gently warm up to room temperature (this can take 24 hrs).
Turn the charger on
Plug the “recovery” charger into the discharge port of the Sur Ron battery (the orange colour plug – see phot0) and allow to charge until voltage is above 54V or until the charger shows a red and green LED light (this can take several hours – the charger will not be damaged if left overnight and has an auto cut off – pleas charge in a safe place).
Now plug in the standard Sur Ron charger in the normal way, and allow the battery to be fully charged and balanced – we recommend a 12 hr minimum charge.
the recovery charger is not designed to fully charge the battery or to balance the battery. Its is simply bringing the voltage of the battery back up to a state where the battery can be charged in the normal way.
