ANL fuses are 80.0 mm L x 22.5 mm W with a mounting bolt spacing of 60.0 mm. They have 11.0 mm bolt slots to fit around two 10 mm mounting studs. MEGA fuses are 68.8 mm L x 19.0 mm W with a mounting bolt spacing of 50.8 mm. They have 8.7 mm round holes to fit around two 9 mm mounting studs...

I have a Lynx Power In converted to a Lynx Distributor without the LEDs. (Thank you YouTube.) One circuit wants to be protected at 30A, but the smallest MEGA/AMG fuse I can find is 40A, and they are slightly hard to find. Does anyone offer a MEGA or AMG fuse in 30A? (Or smaller for future...

I am choosing the Renogy DCC50S over the Kisae DMT1250. The reasons are: 1. The Renogy will charge the starter battery when the house batteries are fully charged. 2. The Renogy has bluetooth communication vs the wired remote of the Kisae. 3. Amazon has a sale offering the DCC50S for $208.16...

Things have changed a bit since I last posted in this thread. I'd like your thoughts. I got a pretty good deal on Renogy RBT100LFP SH batteries, so I bought four, and ended up with six due to shipping error and a great deal ? offered on the extra two batteries. So I am going to set up three...

Can you update the software in Renogy devices yourself? You cannot update software in the Kisae devices except by sending back to Kisae North America. (This is per Ricardo of Kisae NA, and he says they normally send you a refurbished unit with the newest software for a fee. You really gotta...

Not if you are in the US, and have any 240V loads, like an electric range, clothes dryer, and pretty much any whole house heat pump or AC. Many double pole (240VAC) breakers have a single toggle, but they are still breaking two circuits. As an aside, you can use two single pole ( 2 x 120VAC)...

I've seen too many FDLFBR (Friends don't let friends by Renogy) comments. The application is the updating of our 1975 FMC 2900R motorhome to lithium with (hopefully) near term future solar. 270-ish Ah of cooked AGM batteries are being replaced with 400 Ah of LiFePO4 batteries. On paper the...

Yes, of course the batteries would be fastened down. The photo was just a fit test. And to show how shipping foam could be repurposed as insulation and vibration isolation.

We will have a 2000 watt inverter used intermittently, about 196 amps at 12VDC, and another 10-15 amps of 12V loads that generally don't all run at the same time.

Is it a bad idea to insulate LiFePO4 batteries in instead of insulating the battery box? I have four Renogy RBF100LPF12SH batteries. I was going to use closed cell polyethylene foam to give the batteries some vibration isolation anyway, but then I saw the packaging the batteries came in: Closed...

The kind of freeze protection I am thinking of is where the battery isolates the cells when a temperature sensor measures too low.

Thank you. When I was on the Renogy site I did not find a link to their manual.

It sounds like a simple yes or no question, but I could not find the answer on their web site. So I emailed Renogy. And.... The answer they gave me was charts with warning and protection categories for trigger and recovery temperatures. They did not say if the battery BMS actively protected...

Confirmed by LiTime. I contacted them and here's their answer: The 12.8V100Ah mini version doesn't have the low-temp cut-off protection. If you need a freeze protection, maybe you could consider our 12.8V 100Ah smart verison. It will be on stock next month...

If these had freeze protection I would order some right now, but their web page says nothing about freeze or cold charging protection. It would be a shame if LiTime introduced a new battery without programming the BMS to include low temperature protection.

Great. That makes things easy. I may size fuses for future loads in case my loads increase. All wire would be sized matched to the fusing or larger for longer runs. I will likely use a Lynx Power-In with the modifications to add fuses instead of distribution blocks and separate fuse blocks...

Is an MBRF terminal fuse (10,000 A AIC rating for 12 V) OK or do you really need a type T fuse (20,000 AIC rating)? I have read on this form and seen on YouTube videos both fuses as acceptable, and other opinions that only type T is acceptable. The various batteries that I am considering buying...

Is freeze built in protection worth $240 in a 200Ah 12V battery? These batteries would be in a motorhome that spends time in Pennsylvania during the winter. The non freeze protected LiTime 200Ah 12V battery is currently available on eBay here for $509.99. The freeze protected PowerUrUs 200Ah...

I have continued looking for a definitive answer, and have not found it. The closest I've found to an answer is this thread where the OP had one cell that leaked some electrolyte out one cell's vent. And the cell apparently still worked. Regardless, for now I am going to move forward with two...

Hi TorC, I have two places I could put these battery assemblies. (I may only install one battery at this time.) Each assembly would be in a 2 x 2 block of cells clamped or banded together. The BMS, depending on what is chosen, might have to be mounted near the cells, but may not fit on the...

I have a 1975 FMC 2900r motorhome with cooked AGM house batteries, so it's time to upgrade to LiFePO4. The existing 12V nominal power converter would be retired and appropriate LiFePO4 chargers would be installed along with appropriate wiring, fusing, etc. There are two unused awkwardly...
