Added a chain sharpener, 12V grinder, upped the wattage drain to 112W, volts around 12.01, approaching 102Ah
With well over 103Ah, I'm calling this battery a great buyI plugged in a pair of Milwaukee chargers, and am charging my daily drills, 89W
101.1Ah 12.13V
Pulling full capacity once or twice is not bad for a lithium battery. It's required for a true capacity test.10V is almost total discharge, and might be pretty bad for the battery. Unless I wanted to test that BMS Low Voltage shut-off is recoverable, I'd be inclined to shut down the loads at 11.5V (a bit less than 7% SOC remaining unused), let it stabilize and re-check the Voltage again - and then extrapolate from one of our SOC versus Voltage graphs.
Are those screenshots from the BMS App, or from your external monitor App?Nice pic status and history screens

Nope, I didn’t disassemble the pack completely… I might, but opening it up and examining everything was good for me.We're looking forward to you charging it up!
Could you tell what cells there are?
Hi do you know if BMS setting can be accessed and changed ?So far, I am impressed with the battery, well packaged, easily opened up to repair or inspect, well sealed, solid case, bms settings designed to limit to 98% full cells, likely has a high LVD as well, probably 10.5V
I'm at 95.3Ah and above 11.5V
I do not.Hi do you know if BMS setting can be accessed and changed ?

4 day shipping... nice case I haven't seen before.

Looks to be pretty much the same cost per watt as the ec4, but ...
My math has it $200 less money for the same watthours, and lighter to carry. And free shipping, and 4 day delivery from USA warehouse... no Brainerd.Looks to be pretty much the same cost per watt as the ec4, but ...
with the kind of investment that generally goes along with building a battery bank, I'd want someone that would stand behind their product.
Well, I probably messed up somewhere.My math has it $200 less money for the same watthours, and lighter to carry. And free shipping, and 4 day delivery from USA warehouse... no Brainerd.
2year warranty instead of 10 year though...
