Replacing the circuit breakers by hitch
First inspect the wiring. I have a Kodiak Cub 20 foot TT. It has 10 AWG gauge wire from the battery to the 30 amp circuit breaker and 10 gauge wiring to the hitch connector. 10 gauge wire can handle a maximum of 30 amps. The emergency break is also on that circuit and uses 10 gauge wire. So, for that circuit, leave the 30 amp breaker in place.
Current draw from Li-ion battery during short circuit
Ideally you would also limit the current as it''s discharging. 20C on a 2AH battery doesn''t mean you can draw 40 amps all the way until it''s dead. 20C means at 2ah you can safely draw 40 amps, and at 1ah remaining capacity on a 2ah battery you can draw 20 amps without shortening the life of the battery, and at 0.5ah remaining on that same 2ah

Discover key aspects of lithium-ion battery safety with our short circuit testing guide. Learn to ensure integrity and reduce risks in your battery systems.
Murray Wyma Customer Technology Manager Enatel Christchurch,
Short circuit testing on lithium-ion batteries has been carried out to determine their ability to trip a load circuit breaker vs the battery breaker itself, vs the internal BMS.
Suitable Circuit breaker between multiplus-ii and battery
Another reason is that you cannot use a regular AC Circuit Breaker on a DC battery circuit - it can easily catch fire! See AC Circuit Breaker 230V DC Test. A DC fuse and holder is also a lot cheaper than a similarly rated DC Circuit Breaker. [Edit] I see that the ABB breakers in your first post are DC-rated, so will work.
How to Test Lithium Battery?
How It''s Done: To conduct a capacity test, the battery is fully charged, then discharged under controlled conditions until it reaches a specific cut-off voltage (usually between 2.5V and 3.0V for lithium batteries). The amount of energy the battery provides during this discharge is recorded, which is compared to the manufacturer''s rating.
Lithium Batteries tripping breakers??
A single 100 amp hour lithium battery may absorb 50 or even 100 amps. 7 pin connector systems to tow vehicles often are limited to 30 amps. This is good since higher current can damage some alternators. Normally the resistance in the tow vehicle wiring and the trailer wiring limit the current so circuit breakers don''t trip.
Battery fusing recommendations
Smartguage goes into detail regarding battery paralleling, well worth the 15 min read. Wiring Unlimited is a good source of info, essential reading. Fusing for a 12v high current system is costly. Dont cheap out. A proper 300a circuit breaker will cost half a weeks wage. Decent fuses and fuse holders come in much cheaper. Above all KISS.

How do you tell if a Li-ion battery has a protection circuit?
I bought a li-ion battery off of ebay. The listing claims that the battery has a protection circuit, but a week later, the battery didn''t cut out or anything. With a multimeter, it is reading 10V when the battery is listed at 10.8-12.6V. Does this mean the battery doesn''t have protection or should the cutoff be lower?
