Greetings: Your friend will need at least 12 @ 220 amphr 6 volt golf card batteries to run that motor for more than an hour. A 175 amp motor that runs for an hour uses 175 amp hrs (if run at full load). Generally a battery should not be discharged more than 80% of its capacity or battery life will be shortened. It is even better to not discharge the battery more than 50-60% if you want to get the full life from the batteries. The deeper the discharge, the less discharge-charge cycles you will get before the batteries need replacement. A typical 220 amphr 6 volt battery costs about $60-$70, so your friend will spend around $700-$800 on batteries. That cost will allow him to get a good 1.5 hrs before a recharge is needed. Interstate batteries carry these golf cart deep cycle cells, or as someone else mentioned, Trojan makes good batteries. Remember that you get what you pay for. I would recommend against gell cells unless the application requires significant motion such as tippng. I do not think they have more capacity than lead-acid batteries and they are more easily damaged by overcharging. Another common battery is called an L-16 or LV-16. They are 6 volts at 350 amphrs. They can last a bit longer than the golf cart batteries, but are much larger and cost more. A used fork lift battery might be a good option if you can find one in decent shape. Let me know if you live near Rochesster, NY and I can put you in touch with the area's battery guru who might have what you are looking for. BTW, my entire house is run off of 2 used forklift batteries. Each battery weighs 3,500 pounds. They are 48 volt packs and each have 850 amphr capacity. New they cost around $4,000, but I got each for about $1,000. A wind turbine and solar panels keep my batteries charged. Best of luck. Doug Stockman
