I am very DIY, but your solution is so clean and well thought out--and I didn't want to order from several different places, etc.--so I just ordered the turn-key unit from your site. Thank you for all you do for us DIYers. I have built several 48-volt LiPo battery banks based on what I've learned from your channel.

Thanks for all the videos, I made a solar charger trailer for my ebike but I only have a max of 90W (3x30W pannels) that I run in 12v setup. I use 4x 12v lead acid in parrellel and need to remove weight.After building and realizing I was over weight I thought I checked the price of lithium and pooped myself, thought it was hopeless for me. Thanks to your videos and site I just need to save a bit and build some powerbanks better then I thought I could get. My solar setup over charges my lead acid and a bit over amps, best conditions I get 6amps. Will be nice to have something that can actually eat 6amps.

Hello @jehugarcia , appreciate for sharing your knowledge. I just received this 12 v battery exact same bms is on the way. can I get away using the bms without the extra board? I guess question is if I attach the bms on the side, and use small wires to connect to the pins on the battery. main discharge leads will be same leads on the battery right? some other BMS's have bigger wire for leads. but I don't see any big lead wires on this BMS.

I love the clean design. Is there any concern that these cells specify 3.5v max when typical Lifepo4 cells are 3.65v? Maybe a configurable BMS could ensure the cutoff is set to 3.5v to accommodate these.

Hey @jehugarcia, when using something like this to start a car, would you have any concerns about the BMS disconnecting the battery while the car is running? I've heard a bunch of KZitemrs warn of a large voltage spike occuring when the battery is disconnected, which supposedly will "fry all the electronics". Is this a legitimate concern? It seems that any Lithium car battery running a BMS would be prone to the same problem? Which makes me wonder, do they run a BMS or not? I'm picturing like Antigravity branded batteries that are marketed for motorsports.

You'd likely save money by building your own battery. If you bought this battery you're paying extra for the bms and also you wont be able to charge all of your batteries all at once, so you'd have to buy your own 72v bms and wire it yourself either way. If you're building an EV you likely will need many kilowatts of battery capacity.
