I have three lithium batteries in parallel with a Magnum Energy ME-BMK shunt on the negative cable for my ME-ARC controller. Would like to have a Victron Smart Shunt for its Bluetooth feature. Is it OK to put two shunts in series or can you only have one?

I don’t have that capability.

I presently have 2 SOK 12v 206ah lithium batteries wired in parallel. They are a little over 2 1/2 years old. I’d like to add another one next spring. However, it seems I remember reading in the past that lead acid batteries of different ages should not be mixed. Don’t know if having them in...

Good point. Thanks

I followed the advice of a van systems solar internet guru and installed a 250a MRBF fuse in a fuse holder directly to me positive terminal on a SOK 12v lithium battery bank. He said in light of the scarcity and prices of Class T fuses that would be acceptable. Since then another forum thread...

Just to be clear. I believe I should install one fuse for EACH battery. Is that correct? Or are you giving the size of fuse for one fuse on the cable connecting both batteries to the battery buss or one fuse at each battery?

Are ANL fuses what I need? Are they specified by voltage, 12v say, or max voltage, 32v? Can I attach them directly to the 5/16” battery posts then the cables or do I need fuse holders? If I need fuse holders I will need very short 4/0 cables to connect the battery terminal to the fuse holder. Is...

4/0

OK 12v lithium batteries in parallel. Max charge current 70a, recommended 40a. Max continuous discharge current 100a each, peak 200a(3sec). I believe I will put a MBRF or ANL fuse on the positive terminal or close to it of each battery. What size should it be? I’ve read 120% of either max or...

Looks like I need to use an ANL fuse at each positive post of my 2 12v batteries in parallel. They have max continuous discharge of 100a and peak discharge of 200a(3dec). What size fuse, volts and amps should I order?

Thanks

I don’t think I was clear. Yes, put a fuse as close to the battery as possible but why put a fuse on EACH battery positive terminal rather than just the one on the downstream battery attached to the cable to the inverter/charger? The upstream battery of the two is attached to a very short cable.

I’m curious why a fuse should be put on eac battery rather than the one on the main cable attached to battery closest to the inverter/charger? Also, the protection from the solar controller, a Victron Smart Solar MPPT 150/85-Tr VE.CAN, is provided by a 100a CB close to the controller. Any...
