Correct cable size between 12v batteries in parallel.
Please assist with cable size required for 2x 100ah lithium batteries connected in parallel? Distance between the batteries is approximately 2meters. The max draw in the system is a 2000w inverter that peaks at max 196amps. I''ve had a few conflicting answers. Just need to know the size of the cable that will connect the two batteries in parallel.
Do I need a breaker?
The 2.5mm2 cable from the PWM should be connected to the battery via a 25 amp fuse/breaker at the battery. This cable is somewhat under size and will introduce volt drops. OK.. so I can use the 6mm2 wire as a connection from the PWM to the battery. Add a 25A circuit breaker to protect that.. and I could get a 16mm2 (25mm2 really sounds a

Direction of DC breaker between battery and inverter
I am just starting out too. But I wired my DC Panel with a 250amp DC breaker. The wire from my battery is connected to the bottom lug (line) of the breaker when it''s in the off position (down). The top side of the breaker is up in the switch position and this closes the contacts and supplies power on the load side to the inverter.

6 Frequently Asked Questions about “Lithium battery connected to circuit breaker”
How does a battery circuit breaker work?
The UPS is interfaced to the Battery Circuit Breaker (BCB) control board using input contacts to retrieve the status of the external switches/breakers and an output contact used to send the trip signal to remotely open the battery circuit breaker.
How many lithium batteries can be connected?
All battery interconnects, busbar and device connections to resist vibration by using nylon insert lock nuts, thread locking fluid, or lock washers (split lock or external tooth). No more than four (4) lithium batteries can be connected. Connect Sun Cycle Lithium batteries in parallel. Lithium batteries must not be connected in series.
How do you protect a lithium ion battery?
Further layers of safeguards can include solid-state switches in a circuit that is attached to the battery pack to measure current and voltage and disconnect the circuit if the values are too high. Protection circuits for Li-ion packs are mandatory. (See BU-304b: Making Lithium-ion Safe)
What is a DC rated battery circuit breaker (BCB)?
These can be equipped with a monitoring device connected to the UPS or BMS to warn if a fuse has tripped or is disconnecting the battery from the UPS. The DC rated Battery Circuit Breaker (BCB) provides still overcurrent protection, if correctly coordinated, even though it is not as fast as the fuses.
Are lithium ion batteries safe?
Protection circuits for Li-ion packs are mandatory. (See BU-304b: Making Lithium-ion Safe) More information on why batteries fail, what the user can do when a battery overheats and simple guidelines using Lithium-ion Batteries are described in BU-304a: Safety Concerns with Li-ion. Intrinsically Safe Batteries
Does a DC rated circuit breaker provide overcurrent protection?
The DC rated Circuit Breaker still provides overcurrent protection, if correctly coordinated, even though its intervention time can be not enough to avoid extensive damages on the equipment and on the battery.
