Update: Also tested one more time, with salt water dropped to -20C! Did not disconnect. Other BMS triggered instantly. The Daly does not have it. For sure

The more I watch your videos the more I want to build my own battery bank.

Happy new year Will.

[guybrock]

This is the greatest channel on YOUTUBE. We appreciate you very much.

[randomtraveler]

You have never let me down with a review.
Your testing methods are consistent and well thought out.
The manufactures are the ones who let you over promise and under deliver.

You are my go to guy for all things solar.
thanks Will, Happy New Year

[LuvYourLife]

A super big thank you Will and you are such an amazing contributor to all us who just want to build/make our own....

[thomasbroderick]

Hey Will, just wanted to thank you for your excellent videos. You are an absolute natural. I'm old, senile and dumber than a bag of hair but the more I watch the more I glean even if only through rote. I wish I could sit with you for just an hour and have you design a system for my little cabin up here in the southern Sierra's. Love your passion. Love your sincerity. Thank you brother.

[professorjedi]

"I'm not sponsored" makes you the gold standard of solar power YouTubers!! :)

[gregorybiggs]

No, Will, the product has let us down, but your integrity has never! When the product was NOT what they claimed, you said so up front! You are very reliable.

[mothrfckr-sn]

Really appreciate you using metric units Will.

[SteveWrightNZ]

You dont have to worry about letting us down, dude. Just keep keeping it real and keep teaching, you doing a great job.

[ds]

Will YOU have never let us down. The manufacturers have and YOU prevent us from loosing money and you do it for FREE here on YT and on your forum. We all can’t say “thanks” enough!!

[RobertSmith-oszj]

Order up an assortment of threaded studs, washers and nuts. You will have full thread into the battery and proper length for double buss bars if you desire .

[wesr.e.]

When you brought out the bag of frozen bananas, I fell off of my chair!
A can of freeze-mist would work, too, but it wouldn't be as much fun.

[salesteam]

I tested costomized dally BMS Low cut off temperature and it worked fine. I asked them to set for cutting off in low and high temperature and fortunately both of cutting were acurate at 0 and 55 degree

[ancienttechnology]

I eagerly await your reviews and builds. You have opened up the world of solar energy for me.

[CORZER]

Fantastic option for us car stereo guys! 100ah in the size of a lunchbox? That is insane! No competition guys are doing this yet!

[GoingOffGrid]

Id take those smaller cells over the larger ones any day of the week, I use that bms you showed at the end, its amazing, it does disconnect in low temps, witch can damage your solar system, cause your never supposed to have the solar panels connected to a charge controller with out the battery being hook up. it can kill the charge controller.

[MrCPPG]

I do not feel let down at all. I am glad you did the actual test so I won't have to. Happy New Year man.

[billl]

No let downs from you brother youre great
