Have been researching quality lithium setups for a while now and love to see these kinda videos. I dont wanna see sales pitches, i wanna see real time data and usage. Have watched Stefan from AllOffroad reviews aswell and he loves his DCS batteries in his 105 :-)
Stephen do you still rate your 250xp SBC alternator paired with these? At a guess that's the "after market" alternator being used in this video too? I love the idea of these batteries being able to take 100 amps each at idle to recharge ... I reckon that's just as big a draw card to making the switch as the increased storage capacity. I'm a 105 land cruiser owner too :)
Nice little video, batteries always look like a good thing👍 I'm sure there's no issue as has been proven many times over the years but there's a bit of a mix up between rotor and casing temps. There is a big difference between these temps as there is only a miniscule contact patch between the casing and rotor - 2 bearings - heck even the stator hardly touches the housing. Only real way to see rotor and stator temps would be with the gun 90° to the alternator and to have it in a coloured mode not the picture mode🤷 can't have it all but. You would still struggle to get accurate rotor temps and usually just end up getting the windings which are still alot hotter then the casing
Also running two, one under bonnet and one in cab. Amazing product from DCS. Would love to see a tear down directly from DCS. Actually pulling one apart, rather than shown as a group of parts on a bench. Look forward to the vid 😉
no problems at all, we shall share some nice pics and tech info shortly on our Facebook page. That staged bench shot was actually quite funny even the stubby was strategically positioned. Even funnier was the list of components, anyone in electronics would be impressed by the correctly pointed out component list, thanks for the free advertising who ever that was.
Yes once the batteries have tailed off (fully charged and gone to standby) the alternator runs the vehicle. Or with our Hybrid batteries our solar regulator takes over and runs the vehicle and both batteries and the alternator go to standby.
Great informative video. Thanks. Do the batteries charge to their full Ah capacity without a conventional 'profiled' charge pattern provided by a DC-DC charger?
Great video, any advice for a 2004 1kz-te prado with 70amp alternator, I have killed 3 alternators so far trying to charge a two battery setup using a vsr, I am thinking of installing a 140amp alternator, will that help?
Same advise as always don't get after market alternators, OEM is best! Get a genuine one then you can run our 180Ah DBS. 70A is plenty enough and if you needed a faster recharge bolt up a 400W+ solar panel on the roof as well.
No our dual battery systems are connected directly to the factory alternator, refer to the wiring diagram here: www.deepcyclesystems.com.au/product/ultimate-dcs-12v-260ah-dual-battery-system-lithium-land-cruiser-200-series/ Also you can watch this video for more information about our dual battery systems: ruclips.net/video/4r96CRmiKrs/видео.html
G'day Paul and DCS crew, love these videos and your products. Any stats on the impact to battery life under engine bay temps vs in cabin? Amazing to see your batteries can run up to 110 deg, market leading for sure! Can't help but be conscious of overall battery life... Seeing the DCS warranty is only 3 years when under bonnet compared to 4 years if installed elsewhere kinda suggests its still not a great idea having them in the engine bay when it comes to longevity. Keen to hear your thoughts?
thanks Jarrod, in a normal environment your looking at around a ~1-2% capacity loss per year. In a high temperature environment (under bonnet) the cells will suffer from a faster rate of chemical ageing we are typically seeing ~3-5% average over the past 7 years. So say 10% after 3 years, so your 180Ah DBS would be around 160Ah after 3 years. Or your 260Ah DBS would be 234Ah after 3 years. Of course depending on how much towing, which part of the country, average distances driven, average DOD's, how they are charged etc.... etc.... many variables. Expected service life looking at easily the average life of the vehicle being 4 years - with all the added benefits of ultra fast charging, weight savings, space savings in the cabins, monster high performance continuous output for large winches and inverters, IP sealed MPPT solar system etc...
@@deepcyclesystems Thats great, thanks for the response. I know its not an exact science given the variability so really appreciate you sharing that based on customer experiences. Have you seen any benefits in using battery heat shields? Should i even bother? By comparison, I've had an 140ah AGM in the engine bay for the last 12 months, and its down to 65% of original capacity according to a recent test! Definitely be placing an order with you guys next...
You want air flow across the batteries in an engine bays, so a heat shield is only going to help if it doesn't hinder that airflow. AGMs are not suitable for engine bays, but the companies selling them won't tell you that.. instead they will tell you lithium isn't suitable for engine bays.
What about a standard (not smart) alternator from an older 4wd? Rated at say 100 amps? How could we be sure that it will not burn itself out if directly charging two 100amphour lifepo4 batteries? This is interesting video but it seems to be only focussed on modern 'smart' alternators, which in my opinion, aren't really 'standard' alternators.
these are maxed out alternators no smarts here - that's the point. We are loading these as 'standard' voltage regulated units. Both smart and older voltage regulated alternators are fine.
You have battery pack temperatures on our monitoring app, so you can see that info real time. Most 4WD engine bays see our batteries typically between 70-85 degrees C.
Every battery cell chemistry is engineered to be stable at 25 degrees C. So yes the longer cells spend above or below this threshold has a direct impact on overall service life.

running the batteries under the bonnet of my 105 for the past two years they have not failed me so far.

Will the alternator stop charging when the battery is fully charged? Your video shows 90A charge current when fully charged.
Yes once the batteries have tailed off (fully charged and gone to standby) the alternator runs the vehicle. Or with our Hybrid batteries our solar regulator takes over and runs the vehicle and both batteries and the alternator go to standby.

Do you know what year the hilux alternator was from in that test? The later 2.8L hilux got a slightly upgraded one
2020
Can I simply take out my agm battery and install one of these batteries charged via a vsr in a 2010 bt 50 4x4
www.deepcyclesystems.com.au/faq/#why-you-can-not-use-a-vsr
Nope you can't mix and match cell capacities or chemistries, more info above.
These batteries are the bomb. Just buy them.
What about Gu patrol alternators? Can the batteries go under the bonnet in one, I imagine not the turbo side.
yes of course! No problems.
Just the sort of info I'm interested in.. Want to fit redundant power system to my Amarok.. Subbed here!
Do we need dcdc charger if I use your Li dual battery system for land cruiser 200 series ?
No our dual battery systems are connected directly to the factory alternator, refer to the wiring diagram here: www.deepcyclesystems.com.au/product/ultimate-dcs-12v-260ah-dual-battery-system-lithium-land-cruiser-200-series/

why is it showing 100 percent charge . I thought you can't get that straight from the alternator?
this is a stress test, we have dialed the voltage regs up to produce absolute maximum power.

What is the ideal 24v Alternator for LiFePo4 direct charging ?
for our DCS batteries that is 27.80V
What about older “non smart” alternators?
The "smarts" are disabled on the alternators in this video.
What about a standard (not smart) alternator from an older 4wd? Rated at say 100 amps?
How could we be sure that it will not burn itself out if directly charging two 100amphour lifepo4 batteries?

What about temperatures UNDER bonnet while driving during very hot day on the beach let's say up north Queensland? I guess a bit different story.
You have battery pack temperatures on our monitoring app, so you can see that info real time. Most 4WD engine bays see our batteries typically between 70-85 degrees C.
@@deepcyclesystems is that going to lessen cycle life at all?
Every battery cell chemistry is engineered to be stable at 25 degrees C. So yes the longer cells spend above or below this threshold has a direct impact on overall service life.
The future has arrived only at DCS
what equivalent rpm (motor) is the alternator running at during this test?
during the max runs it is 4500rpm. When we say idle we are around 900rpm.
When I grow up I wanna own a DCS battery system in my house and car, and boat ⚡ Great info ✅
