And I found it to be so, in fact. It checks everything so that any mistake on the user's part is simply met with a descriptive error on the screen, and no damage is done. It even recognizes when the power supply (the input) is running out of power (like when using a battery) and draws less and less.
There's only one gotcha - the balance connector they use is JST-PA, a different one than what is the de-facto standard - JST-XH. So poop on them for choosing that road rather than aligning with the crowd.
Anyways, reluctant to wait several weeks for a proper adapter to arrive in the mail, I chose the ghetto way, and soldered a JST-XH plug's wires directly, in FMA-style wiring, where the positive is on one end and the negative(s) on the other.
I proceeded to connect the battery:
Alright!! The charger sees the pack!
And then the new contacts started smoking... :( Indeed that was poor soldering at start.
Luckily, nothing was damaged, not the charger nor the power supply and not the battery or its wires. Only the soldered wires fried and stuck to eachother.
So, with a fresh & proper soldering this time, I started the charge-discharge cycles, talked about in the next post.
To save considerable time, I charged one battery while discharging another by using that as the power source.
