Sur Ron Battery Bypass and Recovery Charger

Buy this listing, Will send you shipping details. Send your battery to us and we will return it to you, fully and safely bypassed within 3 days of receiving it.

Having your battery bypassed will allow it to produce higher power and be used in mode1-2 -3 with our “Enduro” Package. It will also free up anpther 6V or range equivalent to about 46% more: HVC 67V – LVC 54V,  to a new  HVC 67v – lvc48v

The Sur Ron standard battery has battery monitoring system known as a BMS with crazy over cautious settings (we belive to allow for all the differnt temperatures in world from counties as cold as winter Alaska to summer in Dubai). The industry standard for a battery of this configuration, is 67V fully charged and 48V low voltage cut off. The  cells are designed to give much more power than the 4600 watts, the original controller is set to – its being starved!

The cells in the Sur Ron battery are design to supply 10Amps per cell continuously and with its 11P configuration is designed to give 110Amps or 6600W continuous or bursts much higher.

Not only will you now be able to have significant power increase (if you buy an aftermarket controller), you will also gain an addition 46% of battery by allowing the battery to use its full volt range. A standard Sur Ron battery has an over safe crazy low voltage cut off (LVC) of 54V. The cells used are designed to go much lower. Changing the battery to an industry recognised level of 3V per cell, The battery can go lower to 48V (16s = 16 * 3V), and increase of 6v or 46% !!!

To go lower than the standard 54v and allow re-charging, we now include our Recovery Charger, normally sold at £59 but now included in the whole package. This includes your return postage, labour, materials, and recovery charger and still 20% for the VAT man.


 Recovery Charger

To recover a Standard 60v Sur Ron battery/Bypassed battery that has been drained too far for the OEM Sur Ron charger to work (voltage below 54V).

This is a lower voltage charger that has been 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 for a long time (three weeks or more) it may still fail to charge.

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).

When back to normal to temperature, place the battery in a safe place (outside of the home always fir charging)

Turn the charger on.

Plug the “recovery” charger into the discharge port of the Sur Ron battery 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 – please 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 by the Sur Ron charger.


Warranties are not transferable.
