Mike95490, I’m not sure if anyone else stated it in response to any of your posts, but I wanted to say Welcome! I have learned so much over my short time on these forums and generally find most members very helpful. Of course there are always a few who seem to not follow the “we are a...

I have been trying to figure out the same thing and can’t seem to find the answer while searching. I have an ATS but am trying to use the AC to DC charger ONLY when it is switched to grid power. When it is on Battery, I want to use the MPPT and panels to recharge, not the AC to DC charger. Is...

I used this to mount my panels on my motorhome. Worked great. https://www.amazon.com/gp/product/B01BU7038A/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

thank you! Bummer it shows it won’t arrive until mid-July earliest. Oh well, I will go ahead and order and try to be patient.

Do you have a recommendation for a “real good DVM with AC/DC AMP reader”? What do you use? Thanks in advance!

Excellent work Steve_S. Thanks for this and all the sound advise on this forum.

interesting. I was getting the impression from these forums that I needed to protect the battery from over charging and discharging. You are saying only charging is really important? How does one prevent damage if the load Draws the battery down too far? Or do other things shut down before the...

Steve, thanks for your hard work and long hours. The community will definitely benefit. I look forward to seeing the finished product.

I bought a Chargery BMS8T from Craig based on his original post that he had some available. He shipped it immediately, it arrived in 2 days, and was exactly as he described. I wouldn’t hesitate buying another from him if he has some when I am ready for more.

Thanks SteveS. I ordered the used TE relays to get me started but look forward to reading about the SSR testing results. I can always swap them into my setup if they prove to be a long term fit.

Thanks for the reply Grizzzman. Do you have a link to what you are referring to?

Forgive me since I am pretty new to all this. I purchased a Chargery BMS8T to use with the 280ah cells connected to my 12v 2200w inverter and 40A SCC. I didn’t buy it with relays and am now trying to figure out the best source of relays to get me started. I don’t want to purchase from China due...

Like Patrick-B I am confused by the N.O. relays. Where would they go in the system? Also, do you have any suggestions on where to get them in the US without having to wait for a shipment from China? Thanks, KevFab

Nice build. Are those CALB 100Ah cells? Where did you purchase those with the busbars and terminals?

Thanks. I’m impressed by this build. Do you happen to know the total weight?

Nice! What are the components used?

I have that same PD converter in my RV. I added a Charge Wizard pendant ($12 on Amazon) which manually puts it in boost mode at 14.4 for a few hours. BattleBorn suggested it for my use case rather than replace the converter. You might want to reach out to them. From the PD website: The...

Thanks for the clarification. I will go try to find it. Thanks

What videos did you see that comment on YT?

Boondox, what battery monitor is that?

I’m sorry, maybe I missed it, but I was looking for that battery that MBR posted in the video

I click on the link and YouTube opens but I don’t see the video with that battery. Am I missing something?

@screebo, please post pics of your cart with battery boxes so we can see how you did it.

To use the pendant, it is as easy as pushing one button so no real burden. The guy at Battle Born said using the charger without the boost won't cause any real issues, but pushing the button to force boost mode a couple of times in a week will ensure it gets fully charged.

I was going to buy a new charger along with two 100ah Battle Born batteries, but after seeing Will's interview with the Battle Born CEO I asked their sales person about it. The sales person recommended that I continue to use the pendant rather than buying the lithium specific charger.

You may want to get on elf these https://www.amazon.com/gp/product/B007HS0PAI/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1#customerReviews. It is a $12 pendant that will force the PD9245 into 14.4v boost mode foe a few hours.

I recently purchased a Victron Smart IP65 and am very happy with it. Yes, it is more expensive than others but the 15A, Bluetooth connectivity, and quality seems to be well worth the extra cost. I really like the ability to be in my living room and check the status of the charge from my...

Good to know. What was the load you tested with those terminals when they got hot and for how long?

I have used these and they seem to do the job: https://www.amazon.com/ZOOKOTO-Junction-Connector-Terminal-connection/dp/B07TBKKML8/ref=cm_cr_arp_d_product_top?ie=UTF8

The attached screenshot from a reseller has a little more info. “The difference between SE and CA series batteries is the SE has higher energy density, and the CA has internal heat separators and 2-3% higher series/pack capacity.”

Thanks Dzl. I didn’t see that thread. Sorry to double-post the same question.

I am new to LiFePO4 batteries and am considering building my first DIY battery. I am trying to figure out the difference between the White 100AH cells and the blue 200AH other than physical size and color. If my goal is a 200AH battery, It seems that 4 x 200AH cells is both cheaper and takes up...

Thank you for your quick reply.

Homer McFly, that is a nice box you built! I like the sliding tops. What toolbox/case did you use and where did you buy it? Is the bottom compartment large enough to fit two batteries?

Sweet. That is going to be one powerful case. So how are you dealing with the screws mounting the equip? How are you preventing them from going through the plastic?
