I have convinced my self to get the 12v/3000w Victron multiplus. Nice all in one package. Just about ready to pull the trigger, abut I keep thinking about 24v systems are more efficient. I have not purchased solar panels yet. My system is only 2 4cell LiFePo batteries under the bed replacing my...

Came home today and found my single cell battery on the charger ballooned up pretty good. Now what? 1) is it dead? 2) should I hook a fan up and discharge it? a little history I bought these new while back, put on charger set to 3.65v. Been on charger for few days. amps 4.62 has yet to drop...

Just heard on Biz news, Rivian automotive will start using LiFePo batteries in there new trucks. Due to Nickle supply. Wonder how this will effect the smaller batteries we all purchase.

Hello everyone, I have see on many of wills vides he talks about getting connecting cables from his site. I cant find any? I picked up a Battery tester off Amazon, --Tenergy 5-in-1 Battery Meter, Intelligent Cell Meter Digital Battery Checker I don't see in the manual, the type of connector...

getting ready to mount my 4S packs into the trailer. typically with FLA they are in a try to prevent leakage. After Will last video about the batteries leaking has me a bit worried. Should they be mounted into a plastic basin? in the event the leak, or do they not leak? thx

My question or advice needed is. Mom n Dad live 100% off grid. 100deg in summer time mid 20's during winter. He has solar, and backup generator for alternative power. Generator is wired to the Sol Ark 12k-P controller. He had FLA for years in a home made 4ft x 4ft plywood box w/ foam board...

We have a Sol Ark 12k controller. It will turn on the Generator when battery supply drops. It will never shut it off. Is this typical? I end up checking the battery level on the controller LCD. If charged, I will shut it off manually. Is this normal? As it gets colder out. I doubt he will want...

In my TT, I am adding 2 - 12v lifPo batteries in series for 24v. I will have a 24v inverter mounted close to the batteries to supply the 110v for the power center. I can't have just 24v in the trailer. I have many motors that use 12v. Is there a device to easily step down 24v to a 12v output...

Below you will notice a typical BMS. if you unplug the balance cable (blue circle), from watching Wills vid, this shuts off the BMS. As in if you connect B- (blue leads) to Neg on battery, then attach meter to the C- ( black) and the battery positive, there should be 0v correct? I get 12v. Is...

Hello all, I'm getting my first set of LifePo batteries to upgrade my RV. My current plan is to swap out the batteries just for extended run time. Maybe in future (next spring) I will upgrade to some solar as recharge source. Either way, batteries are a direct swap, and only a new LifePo battery...

Getting ready to upgrade the lead acids in my RV to some LifePo batteries. I see on many of @Will Prowse vids "dont use your car to charge your batteries". Yes I understand there is a option for new or modified alternator under the hood. With have the 280ah batteries in the trailer, I don't see...

according to my BMS after sitting on charger for almost 2 weeks now, i continue to have #4 cell (on pos output of battery) at 3.5v. The #1,2,3 cells are 3.33 , 3.33, 3.35. The Victron Energy BMV-712 Smart Battery Monitor, shows it NOT charging. I assume this is due to bms shut off from cell 4 at...

Trying to replace my current FLA batteries with LifePo. I have already 8 cells of 280ah. Trying to figure out if I series them to make 24v @280ah, will this be enough? Its winter time, and the RV has been put to bed for few months. I cannot use my Victron 712 to check the usage. I also don't...

Have new cells purchased in forum group buy, watching some of the vids out there about top balancing. I will lay them all in parallel, get the voltages the same. Some I had to hook up the mini cell tester @Will Prowse recommends in one of his vid to get the cell back so its matched to the...

new to your forum, been watching Wills vids for some time. Lots of good info he puts out, lots to digest. I purchased a TT this past year, and after a few trips out and some reading/Youtube vids, realize how those wonderful Lead acids you get from dealer are really not all that great. They run...

As I have been reading posts, the LifePo batteries do not want to be, "trickle charged" or don't want to float the batteries for long term. If I have a RV, battery bank (280ah) on board, with a charger (PD9130LV ) connected on shore power side. What is the easiest way to keep the charger from...

Purchased while back for my TT build. Decided to go with 12v not 24v. Extra parts left over 2 - BMS8T / 300am shunt $80ea 2 - Contactor DCC-300HB - $75ea if you buy all 4 pieces, i can adjust the price

Was just browsing my "Tech for you" ad from Ali that came through email. Talk about long lead time... Mid Feb. This was same for 4 , 8 , 12 cell purchase.

I’m looking at inverters for my RV setup. I keep finding inverters with the typical 110v plugs on them. I will be wiring this into the RV and not removing it. The technical side of me tends to think I would rather have connections on the back side for permanent type. Does it really matter? I...

So i live up in PNW... we get our sun from June-Sept. Even in Sept like today, its 5:30 and there is no direct sun. I found a link from someones bio (http://www.solarelectricityhandbook.com/solar-irradiance.html) about how much solar do you really get in a day... Below the first chart is the...
