RE: Coach batteries and alternators
Hi,
I'd add a small pure sine wave inverter to your wish list. Morningstar makes a super duper one that is 300 watts. Just perfect to run a laptop and recharge batteries. Generators are noisy.
It would be a good idea to consider upgrading the charging path from the Alternator to the house battery bank from the puny OEM wire.
Costs for materials for a solar installation are below $2.00 per watt.

RE: Batteries
Hi wkc,
For four twelve volt see #3 or #4 on this url:
correctly interconnecting multiple twelve volt batteries
#3 (odd or even numbers of batteries)
http://www.smartgauge.co.uk/images/batt_v_new.gif
#4 (even numbers only)
http://www.smartgauge.co.uk/images/batt_new_2.gif
need diagram or instructions on how parallel connect the 4 house batteries. Thanks.

RE: Time left from battery
Hi Cedarhill,
I think it was just an example of the difference in watts between two voltages at the same amp draw.

RE: add electric to gas water heater
Hi,
Google for "lightning rod" and Hott Rod
They are over priced but standard electric water heater elements won't fit the drain hole in an RV water heater.

RE: Time left from battery
Hi mexbungalows,
So where do we find a DC watt meter that can handle 250 amps?
I did find the Doc Wattson--but it is 50 amps continuous.

RE: Batteries
Hi Ken,
If the wiring is done in a balanced manner it is unnecessary to switch them around.

RE: Time left from battery
Hi mena,
You are right...I was getting confused with this post in the thread:
"I like the idea of the meter telling me the Amp Hours. I have a small TC and only have room for 1-125 Amp Hour battery. Came with a group 24 wet battery and I changed it for a group 30HT AGM so I could use 3/4 of the space instead of less than half the space. I see they are pricey. Is there any way to get around that or is that just the price for what it does? TIA "

RE: Electric Refrigerator with Inverter Questions
Hi,
50 watts per hour per day is doable with solar, and a decent sized battery bank.
500 amp-hours of battery bank and 300 watts of solar may "fill the bill".

RE: Battery Charging
Hi,
I'd suggest reviewing how the batteries are wired together. Since there are an odd number, method #3 on the url below is the only way to balance them properly.
correctly interconnecting multiple batteries
Assuming you have 675 amp-hours of storage the range of size for a solar system may be between 405 and 1013 watts.

RE: Batteries
Hi Keith,
This is what is balanced and best for twin twelve volt batteries.

As it often doesn't cost a dime more to do this, I think it is worth the trouble.

RE: Time left from battery
Hi,
With a flood battery Specific Gravity can be used. With AGM there is no way to do that. mexbungalows is right, one needs to track the amp-hours or kwh's carefully to do effective and efficient charging.
I suspect the OP has never fully charged the battery bank. It may take some doing to get back that lost capacity (corrected post).

RE: Iota Equalization Revisited
Hi renoman,
The temperature sensor on the Blue Sky is the key. From the manual "5.00mV/°C/cell". The base line is at 25 C.
5 X 6 = 30. mv X 65 C (delta t @ -40 C) = 1860 mv above where the maximum charging voltage set on the IPN Pro Remote. 14.4 + 1.86 = 16.26 Volts.

RE: Who Wants To Be Our Virtual Advisor? :)
Hi hallock5,
The v-10 from that era can blow spark plugs out of the block. That would be enough reason to steer clear of it.
Scars--thanks, u got a sweet deal...and I just put a Want To Buy on Clist, already have a guy with 1999 Hol Ramb Vacationer V10/66K miles,all records, new tires, wood lam floors, wanting to let it go for $17.5 or so...so yes, Clist is preferred....
@John/Joey..see the USA...no stick house, sold it, no plans to rebuild---yet..5th wheel will be my next option if I cant find MH in next 30 days...thanks for info..

RE: Needing new Battery for TH ??
Hi Dirtclods,
The whole battery discussion swings on what the goals are.
If you want the minimum number of cells then six individual two volt cells is the best of all worlds (600 amp-hours per cell, and up).
If there is room for an odd number of batteries and the choice is between six volt and twelve volt jars, twelve volt wins on capacity.
If there is room for only two batteries twelve volt wins on redundancy and six volt wins on the number of cells.
If a large inverter (1500 watts and up) is to be run at "full bore" then twelve volt wins even against six six volt (assuming equal amp-hours of capacity), due to the larger voltage drop exhibited by the thicker plates.
Flooded cells remain, for the time being, the "best bang for the buck", but the trade off is regular maintenance and a pair of wool pants.
If one does go to agm chemistry, it would be wise to heed the advice of the particular maker on charging parameters, given that the cost of such batteries may far exceed the cost of a good converter.
Most RV's are woefully low on amp-hours of capacity, and many folks abuse their battery bank by going to far lower states of charge than is good for longevity. To me, it is a no brainer to maximize the capacity.
Balanced wiring for battery banks is often hit and miss (mostly miss, I fear). It should be addressed.
No matter what voltage or chemistry is used, good charging practice need to be followed. If that is done, 2 volt, 12 volt, and 6 volt battery banks may last many years.
So, find out the goals, use what ever works for a battery bank, and go camping.
For my further thoughts on battery banks surf here:

What ever you get make sure it does temperature compensation. Your batteries will love you longer.

RE: Do Anode Rods REALLY work?
Hi Mike,
The anode material erodes over time. I'd replace it with a new one and monitor the loss of material on a yearly basis. Rate of loss depends on how many minerals are in the water supply. Where I live my house hold water heater anode needs replacement about every 18 months.
