I will pick a clamp meter up and check, don't have one of those yet. Charging report is from the charger (Victron LP-22) Shunt report is directly from the Shunt (Victron 500amp.) Both provide reports via Bluetooth. Battery charged outside the RV, report is directly from the charger. Battery is...

1 - 170Ah now and one more if this works out. Have a 8000KW Onan for large power needs/use. Yes everything is through the shunt. Don't have the standby on the inverter active.

When you place a load on a LFP battery, how far down does the voltage drop? Is 1 full Volt normal? No chance of that because I remove the battery and charge it in my garage so it's independent of the entire system. Yes and I have one, I'll give that a try on the outlet next to the inverter I...

I'm replacing my gel cell acid batteries with LifePo4 so the installation is inside the battery bay of my 40ft. Motor Coach. The battery tray is located in the right rear bay, directly behind the rear wheels. The inverter is located directly above the battery bay - distance from battery to...

I'm charging my LFP 12V 170Ah battery with a Victron Blue Smart IP-22 charger on custom setting of Bulk @ 14.6V - constant current at 30A - absorption @ 13.8V with variable current down to 0A - Float @ 13.6V charger shows no current flowing into the battery. The report at the end of charging...

A bunch of great information here! Thanks so much. I will be reading this for a bit trying to digest all of this information. I will reset my charger after todays load test to your suggestion above and see if that does a better job of topping off overnight. I never expected the battery to...

I am also thinking that there may be a bad cell. When the battery was delivered it was sitting at 13.3V. I didn't install it for 3 weeks, it just sat on my workbench in the garage while I finished some other projects. When I decided to tackle removing the AGM and installing the LFP battery the...

I ordered their BB350 cable and used the one they sent with the battery for my charger. All my cabling is from Country Coach and is 2/0 so the Anderson plug is used from the battery to the shunt and distribution bus bar (about 14") and the 2/0 cables take over after that.

Yes they are expensive but they do last - got 11 years on the first group and 8 years on this set that I'm replacing. Just that they are soooo heavy!

I will let you know how this all washes out. I have read many reviews on Big Battery that claim they will work out the issues with the customer. I am hoping that is the case as I don't want to have this drag out to long. If we can fix the issue I'm all for it. It's funny, I haven't had any...

Yes you are correct with your math and I should (and will start) using watts instead of amps in my discussions. Big Battery is involved and working with me, I just have never heard of a battery increasing usable current by cycling, but I understand that balanced cells may make difference, not...

Anderson plug comes on the battery and that is what I have on my charger, so I just unplug the battery from the RV and plug it into my Victron charger. This is what I will charge it with until my new Xantrex inverter/charger shows up.

Thanks for the replies. Researched first then bought - watched many videos and read many articles and reviews and majority of information provided here on this forum. LiPo was just me being to lazy to type LifePo4, but that is what I meant 30Ah per hour for 5 hours is what I was expecting No...

Hi guys - Newto the forum here... Bought a Big Battery OWL170 Ah for my RV. I wanted SOK’s but they were not in stock and my AGM bank was dead - I need two, but only purchased one to start out with because I wasn’t sure Big Battery was a good decision as a supplier. They have some reviews out...
