Changing from OEM 12v, 75ah battery to Battle Born 12v, 100ah battery

Yes I may have over purchased.

Please update us in the future after you've used this in the "real world". I'm guessing you'll be happy with the "over purchase".

Originally posted by Beachcamper View Post I spoke to someone at PD about changing my WFCO9855 to the PD9160alv and one thing he said to make sure have an 80 amp short stop resettable circuit breaker. He mentioned the Bussman CB185. Reason was because of the higher 14.4 charging rate. Has anyone had to do this with any of our GD trailers?



Yes I also use one. My Bussman re-settable breaker is velcro'd right on top of my battery. The breaker was also suggested by Progressive Dynamics for use with their 60amp Lithium converter charger.

I am getting ready to replace my WFCO9855 with a PD9160ALV in my 2020 Reflection 303RLS. If I simply replace the WFCO, the wires would still go from the charger go to the panel and then the panel sends the charge out to the batteries. Where does this CB185 circuit-breaker go?

I can't believe how timely this comment is. I was depleting my 2 Battle Born batteries yesterday while testing how long they would last in a boondocking trip. After the test I plugged back into 50amp shore power and the batteries started to be charged by my PD9160ALV Converter at about 55 amps. I was watching my Victron BVM-712 battery monitor on my phone and heard a "snap" in the front storage area, where the batteries, inverter, etc. are, and the charging amps went to zero. 15 seconds later another snap and it's back to 55 amp charging.

I tracked this down to a 30 amp resettable fuse that the converter red wire was going through before going to the batteries. Evidently this was good enough for the WFCO9855 and a couple of regular car batteries but not for the power grabbin' Lithiums! DOH! So I need one of these 80 amp circuit breakers for the charging circuit to go through.

Where is this 30amp resettable fuse?

Thanks in advance,

Jeff

herman If it's like my 303, the resettable breakers are in the front compartment on the basement wall street side under a black plastic cover. There are 7-10 of them in a row at various amperages. Follow the red wire from the battery up to them.

Ah yes, OK I know where that is. Thanks! So I guess I'm not sure why I need to install the 80-amp CB 185 circuit-breaker and where.
