Will it work if i use 12v 7ah lead acid battery as the power source?

Can I use 18.5v,4.5Ah laptop power supply?

No, you'll get Err 2, excessive voltage and it won't work. However I use a spare IBM 15V laptop supply that works a treat

Does this charger have over discharge protection for battery if connected during load and cuts the power?

I liked this charger for a simplistic charge straight through the balance leads without requiring button pressing or the main power leads to be disconnected. FAIR WARNING: I discovered that these chargers have no internal isolation. If you try to charge two battery packs from the same power input with 2 of these chargers while the packs are wired in series (positive to negative to add voltage), it will destroy the chargers. Will this effectively charge packs wired in series if I use two separate isolated power supplies on each charger?

Not a good charger. My charger is not charging my LiPo's anymore. It doesn't come with any manual or any review and it is giving errors that are totally unknown like "Er0","Er2". For warranty it costs very much than the charger cost.

Do not order these pieces of crap. They fail within 1-2 weeks, and return shipping is nearly (or higher than) what you will be refunded.

Excellent charger! Kind of like the CopterX charger but better. 1) End voltage from charger 3s 750mah: 4.20, 4.19, 4.19 2) Charger beeps when battery at full charge 3) Can use this as cell checker at the field Very handy item. Get warm just like most basic chargers, that's fine. Does not overcharge or undercharge, which most other similar chargers have (CopterX, ESky..)
