Battery balancer provides a stand-alone solution

Battery balancer provides a stand-alone solution
A single IC, stand-alone multicell battery balancer for 12V lead acid batteries has been introduced by Linear Technology. To balance battery charge, the LTC3305 absorbs charge from higher voltage batteries and transfers it to lower voltage batteries. Charge is transferred using a lower capacity battery that is sequentially connected across the batteries in the stack. When absorbing charge, the battery also absorbs energy, adding to the total energy in the stack and increasing capacity.
