Sur Ron 60v Battery Repair Service Or BMS Bypass

Sorry Only Ship To UK Mainland – No overseas – Sorry No International shipping


We undertake repairs to standard 60v Sur Ron batteries.
We have a one price fits all which does not increase or decrease depending on the work required.
BMS Bypass If you are seeking to have your battery “Bypassed” this will be of the same cost. Running your battery at higher power will shorten the life of the battery and must not exceed 7500Watts max and never have the throttle held wide open for long periods of time (more than 30 seconds). Removing the BMS for discharge does remove discharge safety features. This modification is under taken with your consent and absolves Electron Cycles Limited from any liability connected with the battery or power from the battery.
Repair work always includes removing the main battery from the casing, checking cell contacts and replacing any dead cells as required, up to a maximum of 16 cells, and replacing the battery back in its case and making safe.
Additional Work (included in the price but only undertaken if required – but not on request)
If required, we will swop out the BMS for an aftermarket 100amp BMS, which monitors: cell balancing, discharge and heat.
If the display is broken, this will be replaced with an aftermarket display/unit within the cost.
If the discharge port is damaged this will be replaced.
All additional work is included in the price but only if necessary.
We no longer undertake this work in our main workshop and therefore we charge a total of £24 plus VAT for shipping each battery to our remote battery tech and from their remote office back to you.
It is up top you at your cost to have your battery deliver to us here in North Devon. Hover for a supplementary postage fee only, we can send you a label so that you can drop at your nearest UPS drop off shop. Your battery must be well packaged and any damage while in transit is your liability. The battery wil be insured for total loss.
Total cost of repair per battery is £196.80 including VAT.
