David, Lee sent me also a direct mail and there is a difference - he indicated that relay 1 needs *TWO* small "NO" contacts, because indeed with only 1 contact the relay 2 will keep its own coil powered from the battery via its own contact. So, the mail from Lee indicates that relay coil 2 gets

Bill, the OP said there is a significant spark when reconnecting the pack to the charger, that is the reason he wants to leave the charger connected to the pack at all times. The proposed diode is to avoid the charger draining the pack when it is not powered. Best I can come up with is to keep

David, On the contrary - when the charger is UNplugged, it is draining the battery, so my question is meant to tell: what if you DON'T unplug it? If it only drains the pack when it loses power, would there still be a problem when you make it NOT lose power? Cor. On Mon, Mar 21, 2022 at 1:54 AM EV
