purchased a flyer battery box and have problems with it from day one,returned it and had it fixed aparentlly with a note that i was the cause of the problem because the ciggerette socket was arcing which i had never used and still have not used.paid good money for a product that never worked and got no satisfaction trying to resolve the problem as you cant ring them direct, it goes strait to message bank so they can call you back if they want to. witch ive had no calls

Approximate cost: $369

For all dual battery systems for four wheel drive vehicles you can't beat Derek's service and product knowledge. He has set up our vehicle and caravan with battery systems and 12 volt wiring etc.
