The 8-volt golf cart batteries arrived over 24 days ago and have just been sitting on the garage floor, discharging.

Measuring State-of-Charge on Lead Acid Batteries

The 914 AC kit uses 8V golf cart batteries and I'm wondering if different batteries like Hawkers or Optima Yellow-Top batteries would be better. Both US-Battery and Trojan have 8-volt golf-cart batteries. With the AC system, I'll probably be pulling less amps and am looking forward to the extended range.

I should be getting the 18 8-volt golf-cart batteries from American Battery Company early next week. As you may have noticed, the blog entries have dropped off rather abruptly in recent weeks.

I'm not sure how much current these golf cart batteries are designed for. Since traffic is really light on Sunday morning, I drove to work (15 miles away) and back to see how the 914 would handle. Shifting was a real pain on city streets since the electric motor changes RPM very quickly during acceleration or regeneration.

Regarding the 8V golf-cart batteries, Mike also mentioned that they tended to either last 3-4 years or die right away (infant mortality). I just got off the phone with Mike at Electro Automotive.

Besides, the PowerCheq units only handle 12 volt batteries and the ElectroAuto kit is designed for 8-volt golf-cart batteries, so a homebrew system will be required. Over the past few weeks I've been trying to contact the folks at Electro Automotive to get the status of the EV 914 kit. It looks like this is going to take some patience.
