Boost your alternator's output with the MAXAMP range of high charge alternators

Many 4x4 owners, when auxiliary batteries are frustratingly running down from day 3 onwards, make the first 'leap of faith' into a splitter system, in the forlorn hope that this will solve their charging issues - it rarely does!

Of course, managing your available power is important, but in most cases there is just not sufficient power to 'go around'. Remember that your original alternator was solely designed to handle your own vehicle's electrical demands - and not a couple of other auxiliary batteries that you added on to keep the beer, and dry Martinis cool!! (The latter, in this instance, will be shaken, not stirred, of course!).

The most effective way to improve the charge into your auxiliary batteries is to up the alternator output to around 120-150 amps for this type of application.

Some people will double-up on their alternators which is also a good solution - if you have room, of course. However, once into mobile fridges, you are probably into air conditioning as well, in which case there will definitely not be room for a second alternator on your vehicle - unless you are driving a Motor home, or similar!

PMP offers a range of high charge, heavy-duty, MAXAMP alternators from 90-200 amps, as well as the possibility of rewinding your existing stator to improve its output (Although this is subject to the make and model of alternator).

Coupling this extra alternator output to our MXS 'Booster Regulator' will also help reduce charging time by up to30%. When charging more than a couple of batteries at a time, it is a good idea to invest in an EBMS (Electronic Battery Management System) of which we have several models - based on the intelligent microprocessor technology. This system diverts current to the most appropriate battery and also makes allowances for the type of battery it is charging at the time (Cranking or Deep Cycling). It also ensures that your starter battery is only charged, and never discharged (unless you manually over-ride it for winching or emergencies).

For those hyper inquisitive people who wish to know how much charge is going where, how much power the batteries are consuming and just how long the dry Martinis will stay cool for; there is that wonderful invention: The Battery Monitor. We offer several versions of this 'Know-it-all' piece of technology - best to contact us and discuss your precise application - preferably over a dry Martini?!!
