The Club Car is one of the most famous golf carts out there but the OBC can sometimes cause issues with charging which can be a massive problem. So, when this happens you will need to bypass the OBC.
What is OBC Bypass In Club Car?
The On-Board Computer, or OBC, in a Club Car golf cart is in charge of overseeing and controlling the procedure for charging the cart’s batteries. The OBC monitors the battery charge and guards against either overcharging or undercharging.
However, sometimes you may need to eliminate this OBC from your Club Car which is known as OBC bypass.
In the bypass process you will either bypass the OBC which means it stays in your cart but doesn’t have any function or you completely remove it from the charging circuit
This alteration enables a direct link between the charger and the battery pack. Thus, as a result the charger can directly charge the batteries without needing any signal from the OBC.

Bypassing OBC on a Club Car is a bit of a difficult process, so it is common for you to think why you should even Bypass it in the first place. But, it comes with some advantages which we will discuss below.
You can use any charger you want
This is probably the biggest advantage of bypassing the OBC. If you wish to use a new charger for your Club Car in case your older charger is damaged, you can’t unless you bypass the OBC.
A non-OEM charger won’t be able to detect the battery bank voltage and won’t begin charging in Club Car models manufactured in 2006 and after if the OBC is not bypassed.
You also won’t be able to use the OEM chargers even in older models without bypassing as rather than using its own charging profile, the linked charger is going to stick to the OBC’s instructions.
Sometimes, the OBC can malfunction and start to cause problems with charging. You can replace the OBC with a new one but that will be an expensive fix.
Thus, rather than fixing it you can just bypass it and keep charging your Club Car like before.
Extend the battery life
Often it can be seen that aftermarket chargers can improve and extend the battery life of your club car. So, in order to use these chargers you will need to bypass the OBC.
