Allan Bullock has many voltage configurations available to him by Bosch. Just tell him the batteries that were in your cart, and he will tell you what combo of Bosch to get. He also could suggest a charger for the voltage that you are considering. Bullock’s phone is 925.292.8565. Though I installed a several hundred dollar monitoring system. I find that **I do not** use it. Once you get to know your new batteries, you only need a regulated charger that will kick out and a **simple voltmeter** on the dash. I know when to charge, just by looking at how many volts my batteries have dropped. My install is seen here under a Smart battery post. Check it out, under my handle. > [@Smart Battery-Lithium Replacement](https://community.electricforum.com/t/smart-battery-lithium-replacement/12901): > > Curious If anyone has experience or input on the Smart Battery brand of drop in replacement lithium batteries. They claim most applications can utilize existing cables and chargers and simply replace lead acid. They are expensive but maybe not a bad option for those less technically inclined? Am I missing something? Have been looking at ways to drop some weight, gain some power and improve steering. --- _[View the full topic](https://community.electricforum.com/t/re-all-battery-questions/13236)._
