Five months ago, I purchased the Temgot 100Ah self-heating battery, and so far, it's been working perfectly. The issue of the battery not functioning in low temperatures has finally been resolved. The battery comes with an LCD screen and Bluetooth functionality through the app, allowing me to check the battery status anytime, which is very convenient. With a five-year warranty, I would be very fond of it if the battery continues to perform without issues. By the way, like your video.
Remogy is running a huge sale. As a newbie here, i am skeptical . . . Why would i buy a Victron battery if i can get a Renogy for about half the price? Or . . . Why would I buy a 'cheap' battery if there are more $$ batteries out there? I don't get it.
Victron has high quality standards and good customer support. That comes at a price. Renogy focuses more on volume sales. I’ve been running and testing Renogy products for almost four years and have had zero issues. I think it’s a no brainer personally, but some people do have bad experiences with Renogy customer service.
My current setup is an 100Ah AGM on a Rover 40A charge controller and 2 100W panels in my off-grid camp in Maine. It is a 12v system, no inverter and no plans to add one. Planning to upgrade to 100Ah LiPO4. My question is about shelf-mode if I leave the camp for extended periods. How do I setup disconnects and in what order do I shut down, disconnect or reconnect and restore power? Do i need a master disconnect between battery and charge controller? Do i need another between the panels and the charge controller too? In my current setup, the only disconnect is between the battery and my load panel. The logic was to allow charging but disconnect the building (water pump and lights). TIA, Steven
I install a main disconnect on the positive battery cable and one on the positive cable between the panels and the charge controller. First, turn off power from the solar panels and second, turn off the main power disconnect for your battery. Then put your battery into shelf mode
I plan on leaving this in my work trailer but our winters sometimes get to 10f. It will not have a constant power supply. I plan on getting the ac to dc charger. If I plug the charger in when say the temperature outside is 10-20f, will the heaters turn on and heat the battery and then charge once it gets to correct temperature? I spoke with renogy and it was hard for them to understand my question somehow ? 😂 Great video by the way
I have Renogy 200w solar panels and Renogy Adventurer controller for my off grid cabin. I’ve been using lead acid batteries however I feel it would be advantageous to switch to a heated lithium battery . I’m in northern Minnesota and temperatures will get well below Zero in my cabin for extended periods of time. So will the heated battery work?(even at night when the solar panels are not producing). Also how safe is a heated lithium battery?(any fire hazard?) Thanks -and good videos!
Yes, you should definitely get a heated battery! The battery only requires heat when charging so during the night the batteries don’t have to heat themselves since there is no power coming from the panels. This is the perfect application. Heated lithium batteries are safe. The BMS will shut everything down if it senses a high temperature.
@@michaelrapatz5818 any update? After sitting in the cold all night below 0F do they warm themselves up with the sun/solar to ~40F and then start to accept a charge?
@@largedaryl I haven't really had a chance to fully test the battery. When I received the battery - it was not fully charged. I took it to "Batteries Plus" to charge it to full capacity(A Lithium battery needs to be charged with an appropriate charger) I decided to wait until Spring to test it out.
Is the only way to know current battery % with the Renogy BMS? Ive been using a cheap amazon shunt monitor which has worked well for my AGMs, but if some of the power going into the battery is being used for heating, not charging, it seems a shunt style monitor would provide false state of charge info.
That’s a great question. I think your probably right but i also use an exterior shunt and even will travelling in -35, I haven’t noticed a large decrease do to the internal heating elements
My experience: Within 1 week of 20a dc-dc charging at about freezing (32F) temps, the self heating function seems to have broken. Renogy says I have to warm up the batteries first before the heating will turn on (no, I'm not kidding)
Each battery can take 50 amps so you should be able to charge them at 100 amps. You’ll know quickly because the BMS will shut down with overcurrent. Make sure you wire them correctly in parallel. With that said, it’s better to charge batteries at a lower current so they last longer.
Hallo, Möchte mir auch so eine 12V 100Ah LiFePo4 mit Heizung kaufen. Möchte ich in mein VW Bus T4 einbauen. Wie hoch ist die Batterie bis Oberkante Pole.Laut Webseite 187mm. Könnten sie mal die Maße geben. Grüße aus Germany

What if battery temps are at, say -15C (5F)? I’ve spoke to 3 Renogy customer service reps and had 2 say I would need to heat batteries manually in this situation and 1 say the self function will work “2X faster from -15C to 0C if system is “on”” but I’d have to manually heat batteries if system was “off”… any comments on this on this? 😅

Never heard of that brand but I will certainly look into! Glad it’s working well for you.Thanks 😄
@@madetoexplore follow you, hope you have more good video.
We just put 3 of these in our van, I got tired of worrying about our batteries during the winters here in Colorado
Yeah, it’s really nice to have the piece of mind for sure!

Thank you guys so much for watching! Do you need a heated battery for your off-grid solar system?
Nice! hope we have a chance to work with you also!

@@madetoexplore Thanks for the quick and detailed reply. Now I just have to wait for mud-season to pass before I can get into camp.

what is the app you have on your phone for this?
I use the DC Home App

So if you connect 2 together is its charge rate still 50 amp ?

How many amp hrs did you get from a full discharge?
Got 104ah on the self-heated, 106 on the standard lithium, and 202ah on the 200ah BT lithium.

Yes, the battery will auto heat depending on the temperature of the cells.
