Per BFL, “PT why are you still looking at LFP’s??”

Though LFP’s are not for everyone, my sense is that PT has had a bit more time to weigh his options and consider their advantages against their potential cold weather disadvantages… I did the same (i.e. during neighbors camper LFP build and testing…), and is always what one needs to do - no harm in this whatsoever, JMHO

it could be possible, you can reduce the cost of batteries by up to 80% probably on grade A cells if you reduce shipping enough and get a big enough volume discount.

PT, why are you still looking at LFPs? You are supposed to be getting a bunch of SiO2s last heard. I see Azimuth still has 37 of the 50 they got before Xmas, and no drop in price. Noted where you said there is a deal on getting 50. Hmmmm. Shelf life happening!

We don't even know if you have your RV back home yet. Are you in fact going to join the Rv Down South and get LFPs for it?

What is really going on? We deserve to know! Bated breath of the multitude wanting answers. [emoticon]


Hi BFL13,

No Li batteries in my future. The RV has been in storage for 17 months, and will be there for some time. So there is no great rush for me to get anything. I'm considering 1400 watts of solar. The existing batteries are in usable shape, so I may do solar first.

I don't think I'll be doing any of the upgrades I wish to do until summer of 2022. The USA border is still closed to land traffic. As the D variant spirals out of control, and vaccinations are simply not happening, I may not be going south again this year--at least not by RV.

3tons,

If I could find a true cold weather Li at an identical or lower cost per cycle as SiO2 I would consider it. But that means it needs to be usable without heaters at -40. So far that is only Lithium Titinate--at about 4 times the cost per cycle. SiO2 are a better choice for me.

As Mex is fond of saying "every thing now comes with a life time guarantee". SiO2 will outlast me.

If I do upgrade solar it may be best to redo the roof membrane first.

My ride is a 28 foot Class C, 256 watts solar, soon to have SiO2 batteries, 3000 watt Magnum hybrid inverter, Sola Basic Autoformer, Microair Easy Start.

PT thanks for the update. So is the RV stuck in the States?

I just did a major job on the roof of our C and had all the solar off to do that. Only put back the 275w panel, so have three 100w panels doing nothing for now--don't need them on the TC. 275w is enough for what we do nowadays. (Yes, you can have too much solar! [emoticon] )

Hope it all works out for your situation eventually. Agree that Covid problems are not over by a long shot so "stay safe" still applies. Be good if we can get back to "normal".

BFL13,

No, it is in storage in Regina. I will demoth ball it at the end of August for some long overdue piano tuning out of town work trips. That is "IF" covid cooperates.

For those trips, I'll be using the existing batteries for load support.

One issue will be getting the fuel out of the generator.

I think I found one for you. albetra li makes a extreem version that has an added feature, if the batteries are below a spicifc temp the charging current will be re-routed to an internal heater untill the batteries are warm enough and then they will charge.

sorry didnt see the "with out heaters", I just thought that this is a neet way to do it as it is all automatic and doesnt use the actual battery power to warm them up.

Mine's been in storage (beside my house) since March 2020. The advantage is that I can run the generator monthly so I don't have to worry about the gas.

I have seen that add and decided to try it using a protected card.
They do not take Pay Pal. (Which adds to the suspicion) but I do expect it to be fraud. However even if it's only a 15AH battery.... I can use it.

Bump this thread in a week or 3 and I'll have more

Opinion:
This has all the earmarks of being an off-spec UL-1 garden tractor battery that the Chinese are trying to dump. No reputable vendor wants to touch it so it is being sold as an E CAVEAT EMPTOR special with no recourse for claims or warranty. Factory manufacturers lose much face in China when they get stuck with a couple hundred pallets of unsellable merchandise. But word gets around quickly in the mass import markets. Remember the THUNDERPROOF INVERTER? The price kept dropping until it could be had for seventy dollars. Customers posted horrible revelations about smoke, flames and wild electricity. A friend bought a pallet of Chinese clothes irons that were epoxied without being soldered. He paid a dollar. But they had "burn proof" 3 meter silicone power cords. About 15 gauge. The irons went to the iron recycler in Ensenada, and we had 72 power cords for a dollar. The 620 mile journey was a negative.

With regard to the latest garbage offer, someone with a 12-volt CPAP Might want to take a roll of the dice and see if they come up with 12-***** boxcars, line inn. But stake your bet this is a 20 amp hour minus 20% usable battery. 16 amp hours which would get someone through the night for a period.

Mex, that’s a good point, even as a lawn tractor or power sports battery it’s still half the usual price of a conventional battery which still lasts only a year these days.

I’m going to order a couple, purely as an experiment.

Estoy muy agradecido por su ayuda.
