Hi Manuel, I’ve had the battery built with the cells installed in my caravan (RV/Trailer) for almost two months with no issues. I haven’t done a full capacity test but we’ve discharged them down to about 30Ah during normal use. I installed a renogy shunt with screen inside the van to monitor...

My RD6018w kit arrived a week or so ago and has been put to good use. Charging my LiFePO4 cells, running a CB radio, charging my car battery, and helping to diagnose a parasitic draw issue on my car when using a multimeter and ammeter weren't quite enough for the situation. Really like it, easy...

Cells, RD6018w bench power supply and Daly BMS have arrived. Connected everything and doing an initial charge before top balancing. Tested low temp cutoff set at 15C and 0C using salty ice water, works great and immediately. Did some tests on voltage protection as well, setting the cutoffs...

I searched this thread but didn’t see this mentioned, figure this should be noted in this thread. The Daly Smart BMS I just received - 4s 12v 200A model R05W-FL04 - does have a working low temperature cutoff. Just tested cutoff set at 15C and again at 0C, disconnects immediately when the set...

Nice find! To clarify, the review says the 1200W fits inside the RD6018 case, so that is great.

The power supply they sell with it is 800W so you can do 12v or 24v stuff at 18A but not 36v or 48v. It can use any power supply that's 65v+, given a high enough wattage. But over 1000W PSUs probably won't fit in the housing they offer.

Riden sells 6, 12 and 18 amp 0-60v bench power supplies. Search RD6006 on Aliexpress. I have just purchased the 18A version based on reviews here and YouTube, haven’t received it yet though so can’t comment myself. It seems fairly well regarded and there is even a Russian guy who has coded...

I just bought this same meter (branded as AUTENS, but actual branding on the meter is HABOTEST) on Amazon's Australian storefront: https://www.amazon.com.au/gp/product/B07WJ99RP1/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 More robust than my rinky-dink Jaycar meter. (Jaycar, an Australia...

Another factor is how shading will affect your power generation. Shade will, of course, prevent power from being generated - it significantly reduces the current (amps) a panel puts out. It does not affect the voltage of the panel. When you have your panels in series, the voltage gets added but...

Oh gotcha. Yeah that's very close to the recommended charge profile for LiFePO4. I think it's fine, can't imagine it would hurt anything and you'd just end up with slightly less capacity with the lower voltages - but I'd also hope for somebody with more experience and knowledge to confirm.

you’ve got 8 x 200Ah lifepo4 cells yeah? If you connect them all in series you will have a single 24v battery, 14.4v isn’t enough to charge them. You could make two 4S batteries and charge each with 14.4v, but it’s not enough to get them to 100% SOC. You need 3.65v * 4 cells = 14.6v to get to...

The voltage may be the same but due to the voltage profile of LiFePO4 cells the state of charge may be significantly different. The possible consequence of not doing a top balance is that the BMS is never able to fully balance the cells and you end up with less capacity. The BMS will stop...

I remade my diagram with images as the boring shapes were kinda hard to read for me. I realised my main breaker was far over-rated. I've changed it from 200A to 150A. Calculation: ((1000W / 0.85 / 12v) + 20A) * 1.25 = 147.55A ^ ^ ^ ^ | | | |...

Besides the discomforting name “Chance Electric”, this review has me concerned on a few levels: “Since the order in 13 days! The BP fan turns on only when heated, what!? Check yet failed, everything is adjustable, there are multi-werewolf summaries, satisfied while” I do not want multiple...

Oh, right, I missed that the psu is adjustable. I didn’t realize some of them had this feature, thought you’d have to buy a converter of some sort to get that. Good to know.
