Hilux 4x4 Forum

Nog n dual battery thread.

Ek wil by julle hoor of my plan gaan werk?

Om bietjie plek te spaar agter en omdat hy vinniger laai het ek gedink om n high cycle battery voor in die engin bay te sit wat deur die alternator gelaai sal word , die battery sal gebruik word om net my canopy ligte,water pompie ens (dinge wat nie baie gebruik gaan word nie) krag te oja en winch..
en dan agter 1 deepcycle battery wat deur my dc-dc charger gelaai word vir net my 2 x 40 l yskaste gebruik sal word. En dan op n manier as die paw paw die fan tref dat a 3 batterye saam kan werk.

Sal my plan werk? Het julle enige ander idees of help?

Hi AJ
Hoekom laai jy nie al die batterye van die altenator af nie ?
Ek is seker die altenator gaan die agterste battery vinniger as 'n DC-DC charger laai.
Een 105a/h battery behoort die ding te doen vir wat jy nodig het, mits jy nou nie langer as 'n dag of twee gaan staan op een plek plek nie, indien wel, stel ek voor 'n 65/75a/h voor en 105a/h agter.

A.J. ek praat nou onder korreksie maar ek onthou vaagweg dat iemand die opset al probeer het met 'n charger maar dit het nie goed of glad nie gewerk nie.

Ons staan partykeer so 4-5 day sonder enige krag
So ekt gedink om n 105a/h high cycle voor in te sit.

Die dc-dc charger is veronderstel om my deepcycle vinniger te laai as die alternator dieselfde een wat hulle gebruil op die seiljagte wat met son of wind werk.
Dis ek dink n a 4 stage laaier.

AJ, 1 battery vir X2 yskaste is nie voldoende vir 4/5 dae sonder krag nie.

Kyk eerder na 'n solar paneel so 150watt om jou twee batterye voor en agter the laai

Ek het 2 yskaste agter in, met twee batterye, en 'n 60w solar paneel. Dit is nie voldoende nie

AJ, stem saam met Mark. Jy sal maar die geldjie moet spandeer en vir jou 'n sonpaneel kry.

Net so vir interessantheid hier by KaapAgri verkoop hulle a 120w opvoubare sonpaneel vir R4999.
Weet nie of dit goedkoop is of nie.
Is dit reg dat 120w vir jou 10 amp sal gee.

George, daai is nogal 'n aangename prys.

Nee George / Heinich, nie so aangenaam nie. so R20.00 per watt is aangenaam.

Ek kry details vir julle, hulle is hier in Kya Sands...

Sjoe dit klink goed

Stuur dan maar die details please..... Ek sit tans op R5,500 vir 'n 150W paneel (daai opvoubare modelle).

Hier is hulle site: http://www.rectifier.co.za/" onclick="window.open(this.href);return false;

Ek sien hulle adverteer nou vir R19.00 per watt

Flippen cool.So vir 'n 75w is R1425

Ek verstaan ekt nie genoeg krag vir 4/5 dae.

Ek wil net weet of my plan gaan werk om my batterye vinnigerte laai.

Sonpanele is op my koop lysie, maar eers bietjie later.

Met daai AD /DC unit moet jy krag van erens kry? Dis die probleem....

Eish waars jou bril ekt n DC-DC / 12v-12v charger

Dis wat ek bedoel het....sorry....maar jy moet nog steeds krag he om krag te maak?

OK terwyl ek ry sal hy krag kan kry van die alternator af.

Ek het so 'n bietjie gelees oor die DC/DC charging en dit lyk of daar definitief iets steek daarin. Soos ek verstaan verkies 'n "deep cycle" dit.Sal wil hoor wat F_D se komentaar is.

DC-DC charging is defnitief 'n opsie! Ek het lankal die Benton ouens gevra om met so iets uittekom, en finally stel hulle belang in die storie. Dit gaan nog 'n rukkie wees, maar "all good things come to those who wait!" :)

So as ek jou reg verstaan, is die 2 batterye nie direk gekoppel as jy die DC-DC charger gebruik nie? Wat gebeur as jou MAIN battery se charge baie laag is? Is die charger "protected" sodat die "AUX" battery nie sy charge "dump" na die "MAIN" battery nie?

Ek vra, want dis mos hoekom mens gewoonlik die 2 batterye "isolate" sodat dit nie kan gebeur, en jy dalk 'n spontane brand onder jou bonnet het nie?!

Ek vra maar net, want eendersyds ken ek nie DC-DC chargers nie, en andersyds weet ek net dat hulle relatief duur is, sover ek kon sien.

Jip die DC-DC isoleer die die batterye van mekaar.

Battery Management System
MULTIPLE BATTERY MANAGEMENT SYSTEMSThere are various Dual battery management systems, or battery isolator models on the market. Some use Diodes, other use Contactors or Relays, and some use solid state switching devices. Our experience, however, showed us that the problems experienced in the energy/power requirement fields of the4x4 industry, is a little more complex then just a case of retro-fitting another isolator to the system.

The shortfall of most dual battery systems boils down to the inability of the batteries to accept full charge, in either a short period, or at a low recharge voltage level. As a total solution to the multiple battery management system, we focus on supplying a holistic solution in our EBMS multi battery systems.

The PMP multi battery management system looks at the recharge-ability of the battery, combined with the ability of the alternator to produce optimal power. We therefore offer an intelligent battery isolator (Multiple battery management unit) that has the ability to "talk" to the alternator - which is controlled by a special regulator. The EBMS150 (Isolator and battery management unit) coupled with the MXS (Special alternator boost regulator) work together as a unit, but can also be operated independently should the situation require it.
•Battery isolators (Multiple Battery Management unit) ((such as the EBMS-150) are recommended in DC systems with two or more battery banks that are functioning in an isolated position of each other.
•The multiple battery systems have to be installed between alternator or charger and the isolated battery banks. The benefit of the solid-state battery isolators (Multiple battery system) is that the charge process for both batteries happens completely automatically - without utilizing any mechanical parts.
•The voltage drop is minimal between charger/alternator and battery, caused by the Mosfet of the dual battery management unit, is automatically compensated for.
High power, MAXAMP Alternators equipped with the MXS 3 stage regulator, will charge the correct way - if the sensor wires between the MXS and the battery poles are connected. Any cable losses will now automatically be compensated for. The EBMS 150 multiple battery management unit and gives priority charge to the battery with the lowest voltage.

Makes for interesting reading!

Ek wil by julle hoor kan n mens n high cycle en n deep cycle "conect" met mekaar?

Parralel of in serie my skool opvoeding laat my nou bietjie hier in die steek ek kan nie lekker onthou nie

Ek wil nie 24v he nie net groter battery amp?

Firstly it is not advisable to connect a high cycle and deep cycle to each other unless via the solenoid. They are not alike and will get damaged.

Secondly, when looking to keep 12V with many batteries, connect in parallel, negative with negative, positive with positive thus keeping 12V but increasing number of Amp hours.

Thirdly, the MXS that Rian has posted is available @ http://www.planmypower.co.za/ for a fairly hefty price

Im gona ask a very stupid question but wat does a solenoid do ?

Can I fit a switch then where I can alternate between the 2 batteries say when the deepcycle is flat can I switch everything over to the highcycle? or is there something that can do this automaticly.

AJ

Do a search for dual battery solenoid, the explanations given there are top class and will help you to decide.

eish! dis hier op die forum.

Gaan kyk na: http://www.hilux4x4.co.za/dual_battery/index.php" onclick="window.open(this.href);return false;

But the wiring

I fitted one of these
on a 24 volt system for the City of Tshwane, this bus is equiped with a Pa system big amps & speakers conected to a 4000 watt inverter that supplies the power for the system. Since fitment we have had no hassles.

Fitment was very easy. Dont know the cost these days but I definitly suguest it to any one, have done a couple of the relay tipes but its got much more wires
