just found your channel. lots of cool stuff. subscribed. ive seen many
others put the inverter positive on one side of the bank and the negative
to the opposite side of the bank to get an even draw across them all. is
that incorrect? i always thought if you discharge the one on the end, it
will discharge faster than the others. thanks for your vids

You should try and pull +ve and -ve from different ends of the bank. Same
goes with charging.

I usually like your vids….but, I was done with this when U mixed
batteries..u also needed to chuck the two weak telecom batts and run only
the 6 stronger ones…you would have gained a real nice bank..but adding
the weak ones and then mixing in two new and totally different
types….hmmm….bad example and just plain wrong…

where is very nice trick to balance each battery, connect all in parallel,
and for positive use longest wire to positive contact on first battery,
and for negative use short wire for last battery. each battery will have
same resistance path to inverter. Problem ?

Your voltage drop is coming from your termination of the wire, you have to
solder those copper lugs to the wire.

Some good advice has been offered in other posts. Are all your batteries
still good? Did you change up the wiring to be more balanced for charging?
(opposite sides of battery bank?) How are those different batteries doing?

what do you have the batteries in

OK, I’m sold on your ability to completely document a process, and you
apparently know your stuff about batteries. Thank you for your time in
production of this video series!

would this battery bank run 1800watts of lighting (hps) and can i charge
the battery bank with solar pv ? i love your enthusiasm

If you build another battery bank box , use ball bearing rollers instead of
standard wheel rollers. The advantage is they don’t need to pivot and
change direction to roll, they will roll in any direction from start to
finish.
It will roll easier and less force needed to change direction when
maneuvering

I enjoyed the series very much. Thank you for the instructional videos.

Is there a reason you are pulling that load from one end of the battery
bank instead of across it. Is ti because you want to draw from the flooded
batteries first?

What a massive amp draw to run a 12v inverter system your sucking off so
much more current and taking the batteries down so fast. At 1500 watts your
pulling at least 128 amps off those under rated cabling. With a 48v
inverter at 1500 watts your pulling a nifty 32 amp load and your cables
would be over kill. With the batteries you have you could have two 400 amp
battery banks and you increase run time and lesson battery wear. Bearing in
mind the investment of the inverter and a few diodes and connectors. You
could still charge with your 12v battery charger if you add in some hefty
diodes and block the other batterys from seeing each other on the charger
side you would have a rock solid power supply with time to spare. Also shit
happens add in a circuit breaker or fuse off your battey connection to the
inverter so you don’t come home find you lost everything you own due to the
bettery bank catching fire.

Better would be to connect positive and negative oposite on the bank, , you
draw an equal amount of power out off each battery,you do not in your way,
batt system will work better, keep them the same as mutch as possible.

Thats my dream there. But im gonna use a bank of 14V XS Power batteries
each 2400 amps

I see a couple of possible issues with the setup. First the i battery
wiring. Pulling and charging on the same end the battery may cause the
batteries at the far end to weaken due to the resistance of the wire.
Secondly you have two different types of batteries each having different
type of charging requirements.

Cool videos man. Im looking to do something similar to power 220/240 in the
shop at home. I have a lot to learn still before i start spending money
however.

is it better to use a 12v generator to charge batteries and invert to 120v
than just have a 120v generator and run the house with it? and the excess
you charge the batteries with? would require less equipment and no 12v
generator…..
did you just build that whole contraption when a 3kw generator and a can of
fuel would have done the same thing?
Do you have a autoswitching UPS style arrangement where the backup power
automatically kicks in without loosing power? if yes, why? do you have
power needs so important that a few minutes down time is not good enough?
i totally understand the hobby aspect, its fun therefore you do it 🙂 and
with perfect cause 🙂
cool setup anyways, i like your vids :)

Have you considered attaching your draw from the middle of the battery
bank? That would reduce the current running through the full bank before
reaching your inverter.

GREAT WORK,you should use those wires for another battery bank and use 0
gauge shorter wire attached to the double copper pipe. also connect the
positive and negative to OPPOSITE sides of the battery bank. Do it right
the first time and have piece of mind.

Have you figured the cost of a recharge, against the electricity cost to
power your house for a day. I wondered if it was viable or just to protect
against power outages with little or no difference either way cost wise.

Nice battery bank thanks for the info
