RE: Inverter/Converter help?

Ahh perfect. 300 watts will serve you fine. My small inverter I connected behind the breaker/fuse panel. For low wattage you can probably tap into the main 12v battery connection and call it good. Then use a small transfer switch to send power down the branch circuit that powers the convenience plugs. If you have two circuits with outlets you need two transfer switches. I use 300w Go Power sine wave inverter for this service. GP 12v 300w $171 Small transfer switch (almost plug and play) 15a switch $50 Way way easier than 3000w ;)X2

RE: 12v Mattress heating pad woes

Or you can buy one 120V pad and still have it in use after 4 years like ours.

RE: Inverter/Converter help?

Running the microwave, Keurig or other high wattage appliance from the battery bank would be the reason for wanting a 3kW inverter. 2kW will handle those items easily and save you a few bucks. If you're not planning on running anything like that, a 300W inverter will run most anything. Two 6V's is light for a 2kW inverter let alone a 3kW. Most here have four 6V's minimum.

RE: The future of Dry camping and charging with LiFePo battery

you get that in an 18650 liIon now. 2500mAh or 2.5 amps for $4.00 per cell. Problem is it's a 3.7 v cell.Maybe use a small DC-DC converter on the output?

Bump for MEX.

RE: AGM Charge Rates and Times

Those with lower voltage charging sources will be able to charge AGMs faster, but when voltage is pushed higher the gap narrows but to what degree, I cannot say.Or maybe it charges faster at higher SOC's?

RE: Solar Panel Shadows and Bypass Diodes

I would email the manufacturer.

RE: AGM Charge Rates and Times

Most of the companies that sell to the public use the same manufacturers of LFP cells (Winston, CALB, Hi Power, GBS are a few). Price differences between the cells themselves are small and the quality is the same between them (at least I'm not aware of any that stand out). There's not that many available to the general public. The one's you read about you simply cannot buy, not to mention they are custom built and designed for specific environments. The company most used on the racing sailboats is Genasun, I think, and they seem to be accepted as the best BMS manufacturer also. Mastervolt is another. Both are really expensive and only sell pre-packaged batteries (cells plus BMS). I don't know what cells they actually use. Winston CALB GBS

RE: AGM Charge Rates and Times

You mean 5% SOC, right? If you're only using 5% of your banks capacity at a time, wow! Also, I wouldn't consider 5% to be a cycle. IMO, 80% and below would be a cycle. Hey MEX! I WAS going to go LI 5 years ago. If it was only about $1000 cheaper then, I would be running that now instead of the L16's. Price is always an issue.

RE: AGM Charge Rates and Times

Yep, at u.s prices, though. Right now we're getting killed on the exchange. Today I spent $10.44u.s. on EBay... came out to $12.99can!I totally forgot you're from Canada.

RE: mppt vs pwm

On the contrary, there's no need for his behavior. Is he so desperate that he has to put a 34Vmp panel to a 12V pwm system to show substantial mppt gains?You never think you just might be bit out of line sometimes?

RE: AGM Charge Rates and Times

200Ah LiFePo4... $2400 (complete with BMS) Just under $2000 for THIS ONE.

RE: Battery Self Discharge

I'd take a look at the cables and maybe even disconnect all the cables and check voltages on each battery. They should all be really close if not dead even. I know my bank showed surface charge even when one of the 6V was down in voltage due to a bad cable. What really tipped me off was the Victron showing a tenth or two of an amp continuously going into the bank. When my batts are full, the Victron displays 0 amps (takes a few days even after the SG says full).

RE: Battery Self Discharge

jrnymn7, do you have a clamp on meter? I have found mine to be priceless having used it to troubleshoot two bad cables on my bank.

RE: AGM Charge Rates and Times

I've noticed a few come with a 15a charger. How weird is that???I find it weird too. And I haven't seen any large amp LI chargers either. You would think high amps chargers would be more common with LI. Hey Landyacht! For me, the big deal with LI is 80% DOD, lighter weight per amp-hour (even lighter because you don't need as large a batt bank), flat discharge curves and zero maintenance (actual zero maintenance not the don't choose to do any maintenance, zero maintenance). The rest falls in the techie neato category (which I have no problems talking about all day long :B).

RE: AGM Charge Rates and Times

5, 000 cycles. Each discarge cycle should be 20 hours in length. TIME affects battery life. It is an Intregal component of battery degradation. 5, 000 x 20 you do the math. Remember recharging time is NOT factored here. Only time spent discharging. C'mon. You do the math. One hundred thousand hours. How many YEARS is that? For one test. As Charlie Chan used to quip... "Not born yesterday... Born day before.."Check out the DIY EV forums. Those guys have been getting ~2000 cycles from their LFP batts. That's fully charged and discharged (80% DOD) with anywhere from .3C to .5C charge/discharge rates.

RE: mppt vs pwm

mena...! that wasn't 17ampHrs for the day total not 17amps charge rate the remarkable part is he did it with 280w of solar i've done it but i have 505w of solar like he said, the LiFePo have a very slow voltage rise which maintains the the voltage spread and gives the mppt something to work withThanks for clearing that up!

RE: AGM Charge Rates and Times

You can get LFP pre-packaged for $10 per amp hour. Less if you DIY it. http://elitepowersolutions.com/products/product_info.php?cPath=27_49&products_id=241 And that system comes with a charger too.
