I bought one gauge and 4 gauge wire from Amazon The wire that will suggests I'm looking for a chart that I can use so I know what amperage mega fuse to use.

I've seen will on his videos talk highly of two inverters. Growatt and MPP Solar. I'm curious to see what inverters you guys have used and how reliable they have been. I am a commercial driver and looking to put together some lithium batteries with the right inverter of quality. Personally I...

I have two 12 volt 100 amp batteries wired to double the amperage. I really definitely like the victron smartshunt easy to wire up easy to program and easy to use. Not quite done still have to build a wooden box to make it easier when I move between commercial vehicles as well as mounting stuff...

I have decided to go with a 12 volt battery system consisting of lifepo4 batteries. I have a 12 volt 100 amp battleborn and saving money for a 12 volt sok battery and considering going with a 200 amp battery wired in parallel. Is it okay to have a battery with a larger capacity than the other...

As long as the chemistry is the same, the voltage and capacity do you guys think it's okay to mix brands I typically don't like to do that but I have a battleborn 100 amp and I'd like to get an sok now because they're cheaper than battleborn I may be running them at 24 volts I'm just not sure if...

I have 26650 cells more than 240 and 4 charger testers if anyone is interested not worried about money I am a commercial driver in Utah between saint George UT. And salt lake city UT. They are lifepo4 cells. They need to be tested most of the packs are taken apart. I am getting rid of it because...

Just bought some lifepo4 packs to proses. What are the usable volt amp and resistance tolerance and I know to use cells that are real close on the voltage. what is the suggested tolerance 2 or 4 tenths of a volt or so? Thank you

Hopefully I posted this in the right place. I'm looking at a pure sign inverter 400 w minimum for an expensive radio control lipo charger. I am looking at one on Amazon I believe this is a brand will approves of not completely sure. Just wanted to see if the following link if the link is allowed...

Does anybody know if there is a BMS system similar to Batrium but not as expensive. I ask because to my understanding I can use one betrium system to monitor 4 separate 4 cell packs (4 - 4 cell packs is my system goal) I'm sure I'll probably end up using one standard BMS for each pack. Thank...

I saw one of Will's recent videos where he talked about top balancing the cells. I do not have a bench power supply but I have this cheap Chinese one I just want to get opinions on if this is okay to use for top balancing or get a better one from Amazon? It is 50 volts at 20 amps.

Right know i have the battery box, disconnect switch, BMS, Victron battery protect, battery moniter, 12 volt socket and cell checker. I'm thinking of utilizing the bottom bolts on the battery pack to hold them in place still thinking about it. I'll be buying another battery monitor that I've...

I'm looking at 2 battery Moniters on Amazon and I'm looking to get your opinion on this. Here are the 2 I'm looking at. 1. Aili voltmeter ampmeter 350 amp shunt 2. Morning Group 300 amp DC multi function battery Moniter My main concern is the accuracy of the information on the screen I saw a...

This is for Will and anyone else interested. I created two charts one is my opinion on the cost difference between the Prismatic cells will recently did a video on and the possible cost of an 18650 pack of a similar size. The second is a chart which on the center shows the voltage range of a...

I'm curious to see how people reply to this one. I'm comparing the tesla 250 amp 24 volt cell to 2.5 of the alibaba prismatic 12 volt 100 amp packs. I believe that would be about the same price. The tesla cells on Ebay are about $1100 to $1400. And the Alibaba packs are about $400 each plus 2.5...

I got an enclosed box for the battery pack I want to build I believe it is designed for a boat. With up to 400 amps of lifepo4 and 4 bms boards I assume some kind of ventilation would be necessary????? Thank you guys for answering my questions

This question is mainly for will if you see this or anyone who can answer this. There's a video I saw today not sure how long ago it was made from your YouTube account about these white prismatic cells I believe they were a hundred amps they had caps to cover the contacts and I believe you got...

I know the batrium bms cost more than the Chinese set up but I'm just curious if anybody has used these for RV and or mobile packs and what it was like and how it worked out.

The final design of my battery pack will consist of parallel and series wiring it is 16 cells four sets of four at 12 volts each pak 100 amps. I saw an interesting photo on the internet I was curious if this is possible when it comes to the wiring of a BMS or if this might be dangerous? The...

At first my system will be low power for LED lights and a cooler later on it will increase as time goes on. I am looking into using the Lifepo4 cells that will showed on Amazon starting out with the hundred amp ones then later on I may add another set of hundred amp if needed. My main question...
