• LTC3305 Testing Method

    I have designed a 6S 12V Lead Acid Battery Balancer circuit using 2 x LTC3305, but I don't have 8 x Power supply to do the test. I'm looking for suggestion to test the circuit before I connect the board to the battery cell.

    Can I do the following…

  • How to consider auxiliary cell for LTC3305?

    How to consider auxiliary cell (Super Capacitor or Lead-Acid) and What're the advantages and the disadvantages of those two?

    When the battery is charging, It charges auxiliary, right?

  • ltc3305 balancing current too low


    I have ltc3305 battery balancing circuit using two series batteries and an aux battery.  All batteries are 9 A.H types. Circuit balances the batteries however balancing current is about 20-30 mA eventhough series battery voltages are about 13 and…

  • LTC3305 need for auxilary battery


    I got a new project to design a balancer for 4x 12V lead acid batteries. The LTC3305 appears quite often.

    Until now, i know only balancers for LiPo battery packs which where connected while charging. There was never a need for an auxilary battery…

  • LTC3305 - behaviour with batteries disconnected?

    I have an application where I am trying to balance 4 series-connected lead-acid batteries in a backup power supply. I recently started cycling the batteries more frequently, and have started measuring the individual battery voltages, and have noticed…

  • [LTC3305][DC2043B] limiting current to 5A of PS1-PS4 would lead to another problems.

    I'm designing a solution for a solar energy storage. Four 12v@150Ah batteries are used as a storage for energy. Battery equilization circuit using LTC3305/DC2043B is under consideration to be used here. My primary concern about this chip/Eval board…

  • LTC3305 UVFLT & OVFLT Operation

    It isn't clear from the data sheet the UVFLT and OVFLT outputs are pulled low while any battery in the stack exceeds the voltage limits, or only when the individual battery that exceeds the limits is being checked for connection to the AUX battery.…

  • LTC3305 for Dual 24V Batteries


    My electric scooter is powered by a stack of two 24V batteries connected in series. (In fact each battery is a stack of 6 cells of 4 .. 4.05V, but I don't have easy access to each cell)

    Is there any way to use the LTC3305 to balance the two…

  • LTC3305 Auxiliary cell charging speed

    Hi, I would like to use LTC3305.

    So, I have a question. Please help me.


    I am experimenting with the LTC3305 evaluation board.

    Use a super capacitor for the auxiliary cell,
    Lead batteries are used for BAT1 ~ 4.

    I connected…

  • 【LTC3305】Current value during balance adjustment

    Hi, I would like to use LTC3305.

    So, I have a question. Please help me.


    I am currently experimenting with the LTC3305 evaluation board (DC2043B).
