Change to Lithium-ion?

The most Chinese looking battery I've ever seen.

Link doesn't work. Has a space in it.

I am awaiting delivery of 200 ah of these batteries for my Class B. They come with BMS and mounting terminals.

They said all my wiring and charging systems will work. I have a PD4635.

I only have room for 1 lead acid battery of 105ah. So I should have much more amps to use 80% of 200 = 160, vs 50% 0f 105= 52. They're supposed to charge faster and better so I will not be adding to my 120 watt portable solar panel. My only concern is Using it in the 1st week of December can be cold. This is their reply:
Our LiFePO4 battery working temperature is -20 to +60 Degree C for discharging, and 0 to 60 Degree C for charging, -10 to +45 Degree C for stock. And we have done testing at -20 Degree C, the result should make sure battery have 60% more capacity under this condition.

I hope my Trimetric meter will give good info on it's status.

I emailed with the factory to meet my small battery size for 200ah and they came up with a set. They had me buy through Alibaba (a first) for $1,400.

I spend at least 30 days snowbirding in FLA without hookups and some here in Michigan.

What is missing from most converters is temperature compensation. If you camp in extreme weather (-40 to +40) then it is needed at both extremes.

Neither the WFCO nor PD converters are "up to much", but at least the PD can be set to a higher voltage.

I think the WFCO bashing has gone too far. They have an undeserved bad reputation because they are rarely installed correctly, and a very deserved bad reputation from a horrible reliability history that can be traced to poor physical layout of the components. When sized correctly for the battery bank and connected to the batteries with wires that aren't pathetically undersized, the WFCO loaded sensing technique for SOC is more accurate than the no-load voltage sensing of the competitors, and the current-based fan operation anticipates the cooling need instead of reacting to it. The WFCO converters I've had supply their full rated output with marginal AC input, while the PD converters I've had taper their output if the waveform and voltage aren't right at the upper end of the specs.

If they'd fix the reliability issue and emphasize correct installation I think the WFCO converters would be the pick of the litter among the mainstream power converters.

Are you smoking crack? Pick of the litter my dupa. Pick of the litter is something they can only dream of even getting anywhere near close too. Absolute cheap junk which is why they are used.

I can't wait to hear some of the experiences with the WFCO and lithium.

Just finished making the change. Here is a link to the change.

Very nice write up. Avoids speculation about what can be involved including costs.

In the Hot Rod world, there is a movement to the Lithium-ion battery as an alternative to the old lead-acid type.

Looks like performance is superior, but so is the price.

Has anyone changed either their house batteries or their chassis battery to Lithium-ion?

Optima is one of the brands.

Some have. the LI folks claim the batteries have more power per cubic foot and more power per pound as well plus modern LI batteries seem to have a superior life span.

What I believe: They do pack more power in a smaller package and it's lighter as well. For the hot rodders every pound you can shed is Well an increase in your power/weight ration and a reduction in the time to the finish line.. Thus good. (The life span is not as important to them as is the prize money).

To me the price is still a bit high But worth keeping an eye on.

Progressive Dynamics now has an LI converter.. FMCA has a deal with a LI battery firm and they have a deal with PD to bundle the LI programmed converter..

I'm keeping an eye on the prize as it were but I've got several years left on my current Deka G-20's.

And I have a date with a radio in the other room.

TRUE
In the eighties, one Chinese hand tool brand was harmonious butterfly.

Maybe World Friendship is meant to reduce the possibility of having irate customers ganging up and soliciting a private bombing run over the factory.

WFCO is an epitome of GARBAGE CHINESE products.
