yes oversized to start. Thanks for double check

got my hands on some new hardware last night - picked up a Daly blue tooth 4s 12v 200A which will be better suited to this boat project. Plan now is to: use 2500 watt inverter upgrade power and ground bus cables to handle 200+ Amps use 200 Amp breaker use Daly 200 Amp BMS with ABC switch A to...

Working like a charm after I upgraded two things - one the inverter was 20 years old and when I touched the case it zapped me a bit so swapped for new 2400. Two, I had the wrong Amperage fuse/breaker. 40AMP worked fine for A/C, Fans, and small items but if I tried coffee pot or microwave (even...

Anyone got one on a shelf they dont need? Message me if you do. Thanks!

Thanks Filter - based on your recommendations I found the tutorial and see what I am doing wrong here. Will reswizzle it.

Simple question (I hope): I have a 190AH 12V LIFEPO4 with a BMS rated 60AMP discharge and 30Amp charge. It is connected to a new 12 volt 2500watt pure SINE inverter (peaks at 5000). Between the two devices I am running the same gauge wire as the BMS Negative wire. The Plus connects to a 40Amp...

I cant solder to save my life....I think they are junk from ebay to begin with so time to replace them.

Actually the LIFEPO4 is it's own battery bank and does not touch the other 12-volt banks. I think I am going to simply purchase a small 10Amp LIFEPO4 specific charger to keep things simple. Thanks for info!

I use a Guest chargePro to charge 3 banks on a boat. Looking to leave lead acid for starter motors but go LIFEPO4 for “house” battery. Can this work? Home built 75AH LifePo4 battery does not need to be 100% optimized. Thanks as always!

I have two 100watt flexible solar panels from fleabay that stopped working and of course the seller is MIA and unresponsive. Hate to throw them away. Both panels have fried diodes ... can these be replaced by someone with limited soldering skills. Thanks for your ideas/recommendations.

Good stuff Eggo - Thanks. The use case is supplemental A/C on a boat. Every "blue moon" we will want A/C for sleeping or to cool down cabin. A/C is new and very efficient so 1500 Watt inverter drives it without issue and very low over-all Amps even when compressor kicking in. Shutting down...

any feedback?

Thanks all - always helpful! Perhaps I am better off taking the "scrub" mismatched batteries and make one larger lower AH 12V and call it a day? ie. combine the 75AH and 50AH cells into a bigger pack and have an ABC switch - A to Load, B to 175AH pack, and C to 50AH "mutt" pack.

Can you clarify this? Do you mean it will burn down the garage or that it will not allow me to use 100% of each battery bank (which I can live with as long as it is safe? Thanks!

Time to turn that back porch lanai into a solar array?
