RE: Resealing the Edge of the Roof, Dicor, Eternabond, or Both?

Same here, went around all the edges of the roof with Eternabond, it comes halfway up from the gutter, 4" tape. 1st thing I do on any RV I get.

RE: Lithium Battery Question

I can’t fathom camping at -40, I picture everything breaking off in my hand and condensation everywhere ;)

RE: Lithium Battery Question

I didn't see anything significantly cheaper on their website. Canadian Dollar is significantly cheaper than USD. This is what I would buy from them: https://www.lynaclithium.com/product/12v-315ah-llt-lfp/ On sale now for $2197. 300 amp-hours@12 volts. They have a very nice pdf which spells out what the bank can, and can not do, and exactly how it may be recharged. https://www.lynaclithium.com/wp-content/uploads/2019/07/data-sheet-12V-315Ah.pdf This is why I won't yet buy LI: Low temperatures reduce the rate at which the battery can properly absorb current. Lithium ions, with no where to go, will begin piling up on the anode. This leads to irreversible Lithium metallic plating which will essentially begin instantaneously. Performance, output and lifecycle become diminished and the battery becomes increasingly less safe under stressful conditions. Just as FYI, that $2197 CAD = ~ $1500 USD. I worked with Conor (the owner) on my setup directly, as I think I was probably his first RV customer (he's got pictures of my setup on his site). He gave me lots of good information on programming my Samlex inverter/charger and is very responsive. He recently changed the 100AH unit by bumping it to 125AH to show true 100AH at 80% discharge, which I found to be an interesting marketing angle. They're coming out with a cold-weather variant sometime soon.

RE: Lithium Battery Question

I've dealt with a Canadian company called Lynac Batteries. The owner is an electrical engineer and he started with industrial applications then pivoted to batteries. He sources parts in China but assembles here. I've bought 6 100A units, very satisfied so far. Significantly cheaper than the Battle Borns but quality units. Building your own is something I had originally thought about, but the investment of time and maintenance wasn't something I was interested in at the end.

RE: Lithium Upgrade - Converter charger

I echo the sentiment. Get a charger that can be programmed appropriately. The LIFePO4's don't like float/absorb charges

RE: Inverter questions

Keep in mind that a coffee maker has a very high initial draw. On my previous setup, I would frequently get the low voltage 'beep' from a 2000w PSW inverter off of 4 batteries when using a Tassimo (which is similar to the K-cup). That was with 4/0 wiring and full solar. The weak point was the inverter.

RE: Why extra coax connections in 5th wheel?

Is it possible the HDMI from the TV is connected to a radio with a DVD or Blueray player located somewhere else?

RE: Planning a trip Jun 2020 to Nova Scotia/PEI

Bring some warm clothes just in case. We were in PEI in June of last year (towards the end of the month even) and had to wear winter jackets on a few of the days. It did warm up rapidly soon thereafter though.

RE: Microwaves on inverters.

I just recently bought 5 x 100AH LIFePO4 batteries from a Canadian manufacturer (I researched first, and spoke with him at length, he's an electrical engineer by trade). Each battery was $750 CAD. So far so good, they are good quality and easily power my Samlex 3000w inverter. Sure, they are more expensive than FLA, but weight and voltage drop were the primary concerns for me. Not sure it would be assumed that this would be in addition to house batteries or that a separate bank is required... If the OP wants the contact info, PM me. Close to my setup - YES it can easily be done - Ours Works Great 1200 watt inverter microwave used many times during the day but no coffee pot Just yet Our 2Kw sine wave inverter easily powers the microwave for as long as needed The other half of the equation the batteries, charging & Metering / monitoring 200amp/hr LiFe battery bank that is dedicated to the inverter and heater blower motor no other house loads. A 220amp/hr lead acid battery bank for house loads. 600watts of solar and when cloudy for extended periods a 4kw generator with both a 100amp and 75amp converters Build yourself a nice system and you will enjoy it for years to come Any estimate on what a 200amp/hr LiFe battery bank would cost? (Remember, this is IN ADDITION to the house batteries.) Here is a link to a 100amp/hr LiFe battery for $1,300.00. Two of them would be over $2,500.00. I assume that is ball park. LiFe 100amp/hr battery Do you REALLY want microwave/Mr. Coffee THAT badly?

RE: Power awning

We did ours this spring. Only hitch was the delivered fabric was wider than requested, so we had to trim on one side. Other than that it was a simple 2 person job, we did it at the campground with a couple of ladders.

RE: In-Depth RV Lithium Install & Wiring Film - Mike Mas

Very interesting and professional video. Great job!

RE: 5th wheel hitches

We have a 2006 F250 V10 pulling a 10k 5er with the Andersen hitch. I like it for it's flexibility (ability to adjust easily) and portability (don't need a winch to remove it). Glad I chose it, never had an issue other than occasionally needing a hammer to remove one of the pins.

RE: Battery (really solar panel) Disconnect Question

I installed battery disconnects between the array and the controllers, and a single disconnect switch between a busbar serving accessories (MPPT, inverter, etc) and the battery bank. That gives me full flexibility.

RE: Converted to Lithium-Ion be careful.

Thanks for the link, interesting point on reconditioning.

RE: Converted to Lithium-Ion be careful.

Sure, and getting up in the morning and putting on pants brings a risk of falling and breaking your neck. As with any other technology, risk will never be 0, but needs to be measured in context. 7 reports of battery packs over several 100,000 laptops. Bet that there were more issues with someone getting injured because they were physically hit by a laptop than that. I have LIFePO4 batteries in my 5er. Guess what, I also have 100's of pounds of LP in canisters. Funny how no one constantly brings that up...

RE: Electrical Upgrade Made Easy

Nice! I did the same with lithium batteries and a Samlex unit. You'll be very happy with the performance no doubt.

RE: 2 6v batters VS 2 12v

It might also depend on your use case. I initially started with a bank of 6v Trojan T-125's, but wasn't satisfied with the voltage drop on heavy inverter draw. I switched to Rolls-Surrette high capacity 12v (210AH) to help mitigate that issue for me.

RE: Bus Bars - 150A rated ok?

Woah - I don't plan to do each battery individually, not sure how that floated up... I have a full time job already ;) My batteries are all individually wired to the bus, where they take their charge (either from solar when camping or charger when at home), no paralleling, etc. That's why I was asking if there was any significant impact of having different wire gauge for the 5th battery.

RE: Bus Bars - 150A rated ok?

the 600 amp bars seemed a little bit overkill - 4 of them would pay for another battery! So far I've not seen a draw over 230 amps on the inverter, so I think 250 should be fine.
phemens 08/28/19 04:03pm Tech Issues
RE: Bus Bars - 150A rated ok?

For amperage I can draw max 100 amps per battery, in parallel that gives me 500 amps theoretical. Max draw from the inverter is about 250 amps (excluding very short duration peak 6000 watts but I'll never reach that with any equipment I'm currently carrying).
