Lithium Smart battery draw rate in parallel

Hi all


I am looking at installing 2 x Victron LiFePO4 Lithium Battery 12.8V/200Ah-a - Smart in parallel.


My question is by installing these in parallel am I able to increase my continuous and maximum draw rates to allow for a 3000VA Multiplus inverter? I have read that batteries with internal BMS do not achieve an increase in draw rate when paralleled. I am considering running the VE.BUS BMS to manage the system.


I appreciate I will only have limited capacity at this draw level but will consider increasing the bank size at a later date and don't expect to use for long periods (<1 hour).


Any thoughts or experience would be greatly appreciated. Thank you

With two batteries in parallel you will double the max. current.
A single 200Ah Victron Smart Lithium battery is rated for a maximum continuous discharge current of 400A (recommended are 200A).
