I have a 1968 converted Beetle and am looking for some suggestions/ advice. Specifically concerning the charger.

I recently bought the vehicle and it runs great with the 12v deep cycle marine batteries I have put in there. Just got some 29DC everstarts from Walmart.I have 7 of them in series so it's an 84v system. My system has an old K&W BC-20 charger (picture attached) that I can't seem to figure out. It has some adjustments on it and with following the manual available online I was able to get the charger set up right, but it trips the 15 amp breaker I have the outlets in my garage connected to.

- Do I need to bump up the breaker?

- Or do you think I need to go through my charger again because the 84v are getting through?

- Or just replace the charger with a newer smart charger (current charger is roughly 15 years old)?
- If so where do you recommend getting an 84v 20a lead acid charger to replace the old one?

Thanks,
Spencer

That charger is supposed to be on at least a 25 amp circuit.

No, you can't "bump up the breaker".

By bump it up, I mean change it out for a beefier breaker. Curious, why 25?

You have to change the wiring,not just the breaker.

A dedicated charging circuit can't be loaded more than 80% of breaker current. You cannot have other outlets on the circuit dedicated to vehicle charging.

K&W BC-20 Charging Questions

Recently purchased a VW beetle that has a K&W BC-20 charger in it. Currently, have 7 batteries set up in the beetle in series and am wondering how I set it up. The current setup only had two wires coming out of the charger to hook up to the batteries. I assumed the red and black wires were...
