-Samples were available to me of both the '''BattPro''' regulator designed by Mark Hansen and sold by Wilde Evolutions and the [[Rudman Regulator]] designed by Joe Smalley of Manzanita Micro is sold by Rick Rudman, E-Car and others. Since my batteries are placed in tight spacing, and with some on their sides, it was not practical to use the + battery post as the heat sink for the Reg as required by the BattPro. Also living in California with no freezing temperature my battery cases are open to the weather under the hood and in the rear trunk area where the gas tank used to be. Also I wanted to see all the LEDs at once. The blinking LED easier to see on the Rudman than the gradually increasing intensity glow of the BattPro.

 At a electronic surplus store I found an IBM accessory box and mounted all the Rudman Regs in it. A fused lead from each battery junction connected through a multi-contact plug and socket connects to the regs. A pair of wires from each Reg then go to an external 5 ohm 25 watt resistor on a common heat sink. For final equalization battery charge every 2 weeks or so the cable connector can be disconnected to remove the regs from each battery and then fully equalized Optimas charged according to Optima recommendations for the final full charge of 2 A for 3 hours. I will not do this for more than 1/2 hours so as not to over gas any of the sealed batteries.

 My ''(Lee Hart)'' Battery Balancer is an elaborate system that uses a microcomputer to monitor every battery, and charge it as needed to keep them all in balance. It will cost you around $1000, and is open source (see it at http://www.geocities.com/sorefeets/balancerland/intro.htm

	A '''Battery Management System''' (BMS) is some sort of ''system'' for managing the health of the many batteries in an electric vehicle. A BMS can range from a human with a multi-meter, to more automated regulation or power shutteling system. The [[Battery charger]] is generally considered a seperate device though it will most likely need to intigrate with whichever BMS is used.

-Next step up is to automate it somehow. The crudest automatic system is my zener-lamp regulator. It's a couple zener diodes and a light bulb across each 12v battery. If the voltage gets too high, the zeners conduct, the lamp lights, and it bypasses charging current to push the batteries toward balance. These are $5-$10 per battery.

 From there, it all depends on how fancy you want to get. Rich Rudman sells regulators for about $40/battery that can bypass more current, provide indications of over- and under-voltage batteries, over-temperature, etc.
