Hi rmaddy, I’m encountering an issue. Among the 4 battle born batteries, one cannot be charged above 13.8. I’ve tried several times so far. According to BB tech, either i need to discharge it down and recharge it back up to see what will happen or ship it back for them to take a look. What...

Thanks! I will go ahead and order a Victron Energy Blue Smart IP65 12-Volt 7 amp Battery Charger. Do I need to fully drain the batteries before using the charger? If yes what will be the desired voltage or other measurements I’m looking for before going ahead with the recharge?

I have 4 battle born 12v 100ah batteries in 2p2s 24v configuration. Previously I think I over-discharged them so their voltages were imbalanced. So I used a regular booster 12v charger (not designed for lifepo4) to charged each battery up to around 12.74v and then re-wired them to the solar...

So all voltages are the same which is good news. But why are the voltages dropping? Around 2:50pm each was measured at 13.34 but now 4:15pm they are all 13.31. And yes I’m still charging them with the panels but its overcast again today so its about 50-100w. And is fully charged voltage 14.4?

The system is fired up! All four batteries started around 12.70v. Since today is overcast the panels are charging very slowly. After about an hour, the voltages for four batteries are 12.97, 12.94, 12.94 and 12.92. So how do I proceed? Thanks.

Are you sure “boost” mode is safe? The maintenance mode is taking forever

Ok I’m just going to do it like in these photo without the car battery. Btw I just measured voltages for all batteries again they are 10.64, 11.44, 11.50 and 12.63. So I’m gonna charge the first 3 individually to around 12.62-12.64 then fire the 2s2p up again. Let me know if you see any...

Sorry i guess i missed this post. I have attached the jump start diagram. Let me know if you see any issues I don’t wanna destroy my batteries. Also I remember two of four batteries are above 11vol, should i still charge them?

Wait i thought i need to charge all of them and balance them to 14.4v or am i just trying to jump start the controller? My friend has a 12v charger i will swing by when I’m heading home. If just to jump start do i just keep the current 2p2s wiring going and connect the 12v charger clamps to...

I think I’m gonna just order one on Amazon. Anything i need to watch out when charging them? What will be optimum voltage level? I will get back to you once balanced

I don’t have a 12volt battery charger. Is there other ways or i need to order one?

I think I screwed up. I just checked the voltage of my 4 battle borns. Each has a different voltages. They are from about 7, 8, 11 and 12 vol. what to do now?

Actually i drained the battery last night after watching Will’s video to zero set the battery monitor. Maybe i drained ithem too much because the inverter is not turning on as well. Any way to fix? Or any way to jump start the system? Because yesterday after i’d wired everything the...

Yesterday it was finally charging but right now 9am in Los Angeles with sun out it’s not charging at all. The lights on the controller are off and the MT-50 remote is off too. Last night even after 5pm when there was no sunlight still a little bit of charge coming in. Do you know what’s...

Hi GLC, Everything is ready to go. What will be the proper order to connect all of them together? From batteries, inverter, charger controller, to solar panels. Thanks!
