They just went up another $100. Sucks because I was gonna buy 2 but now I'm just going to wait to see if the EG4s come down.

They all have internal BMS'. I've tested the capacity of them and the BMS works properly as it cuts out when the voltage is low.

Need some battery advice. I am looking to replace my 2 6v Lead Acid batteries with these, https://www.batteryclearinghouse.com...2v-22-5ah-pack in parallel using this https://jag35.com/products/dc-pcb-po...32028533457011. Jehu has a video showing the batteries pushing 80 Amps through that PCB...

I have a 26650 battery that I need to make sure I get the correct size heat shrink to wrap it completely. The cells are 4s7p but in a diagonal configuration. See photo. I'm not sure what size heat shrink I need to cover the entire battery. Will 280mm be large enough?

Yes, they are 26650 LifePO4 cells.

Yeah, I think I'll just stick with 16s. Just gonna be a large pack.

I've seen 48v Lifepo4 chargers that say they are for 16s configurations. Can I use one of those for a 15s configuration? I know the voltage is different, 54.7 vs 58.4.

I harvested a bunch of 26650 cells. They were in a 5s7p configuration and I want to configure them for 48v to charge a bluetti or Delta unit I have. Should I do 15s or 16s? I'm not sure exactly what the difference is so if anyone can give me advice that'd be great.

I'm in Santa Monica and San Fernando Valley area. I have 9 of these packs that seem to have a bad BMS. I have them on Jags 3s3p PCB and whenever I put a load on them they drop in voltage. I, honestly, don't have any more time to troubleshoot and am not interested in harvesting the cells...

I built a 48v battery generator using These in series and wanted to know if it is okay to use them while charging them with solar. I have a buck controller that I connect 2 110w solar panels to. Not sure if there is something I need to install. I would be using these to supplement my ecoflow...

What trailer do you have? That tongue box fit perfect. I have an Alpha Wolf 26dbh-l.

I'm doing that using a victron but I'm charging a 12v battery with a 48v pack. As long as the scc input isn't lower than 48v.

I would be able to do 2p4s with 1 BMS, right?

I'm gonna use the 24v to charge my AC200p.

If I want to install a 24v cig plug using 48v battery do I need a 48v to 24v step down converter or can I use the 48v to 12v and just use 2 poles on a fuse block?

Yes, u don't want to exceed the current. I, although, don't see me building a 100v battery bank. Lol

If you already have an MPPT that u use with panels it's just good to know u don't have to buy one more device.

I have a victron 100/15 that I connect a 48v battery box to the PV input to charge my Trailer 12v battery. The Victron will only pull from the 48v what the max PV input is for the 12v battery. I'm assuming any other MPPT would function the same.

48lbs and it's gonna be NCM.

Very surprising as it runs my Trailer 15k AC on low.

To charge up one of the battery packs it takes around 6 hours with 2 110w Ecoflow panels.

It's the Bluetti AC charger that charges the AC200P. I use it with an adapter I bought off bluetti that converts the barrel connector to the xt90 in the battery pack. 3 stage means it dials down the charging in stages. https://www.bluetti.com/products/dc7909f-to-xt90m-cable

I use a solar boost charge controller, CTK300, when not near land power and when by a power source, I use the Bluetti charger. I had to buy the 7909 to XT90 adapter to connect the charger but it works great.

It's the other way around. The batteries are charging the Bluetti. I have 4 12v packs from Jehu in series. Each pack has xt60 connectors then I made a series cable to connect them. Series is when you bump up the voltage by connecting the batteries positive to negative. I then have an xt90...

I have the 12v battery packs from Jehu. I have them in series to make 48v. I have 2 48v packs. I use the AC200P charger to charge the packs. I confirmed from Bluetti that it is a 3 stage charger. Haven't had an issue yet using it to charge the battery pack. I also have a CTK300 Solar...

I would use 24v minimum. But you can use either.

There's sun. It just doesn't go into bulk.

Now I'm confused, it's showing at 12.54 and not going into absorption or bulk. Been there for a while. I have trail set to .4v so not sure what I'm doing wrong.

Its in float now. Showing 12.7. So I'm satisfied with that. Thanks all.

this morning they were at 12.4. I'm only getting at max 10A when in Absorption or bulk. I'll leave it at 14.7 Absorption, 13.0 Float. I was trying to change expert settings but for some reason they don't stick. Is there a trick to saving them? edit: Forgot to mention they are 232AH batteries.

What settings should I use for 2 6v GC2 US batteries in series connected to the Victron 100/20? I have it at 14.4 Absorption and 13.2 float but it seems to stay in Bulk forever. Here are suggestions of battery.

Yes I was able to use it to charge the packs in 4s from jag. It works perfectly. Charges it to 56.4 then cuts out.

It's at 100% so it's not charging but it charges at about 650w. I also have a CTK300 solar charge controller to charge the batteries with 2 bluetti panels. I have 2 battery banks so I can solar charge 1 and use the other and switch out when one is depleted.

I'm doing this the exact way in that video but with 48v lifepo4 pack. I use the ac200p charger to charge the pack too.

Has anyone used a heavy duty suction cup to mount flexible or foldable panels on a travel trailer? Thinking of buying a few of these, https://smile.amazon.com/dp/B08JHZPG84/ref=cm_sw_r_cp_apa_glt_fabc_1EXRZ1YP894K2TAXEFA4?_encoding=UTF8&psc=1 for 3 bluetti folding panels I have while camping...
