Lithium going to sleep ?

[munchie]

If one goes to sleep , I know you can hook two wires to another battery to wake it, but would a perko run charge jump switch do the same thing when switching to battery number 2 if it were the crank battery asleep ? And should it crank just by using the number 2 setting.

Most brands can be woken up by jumping them, be sure its ok with the brand you have, keep in mind if a lithium is asleep/safe mode there is a reason, the most common reason is they are dead, below 10v so when you wake it its still dead and needs charging, for a cranking thats usually ok, you can start the motor and let it start charging , if it were a trolling it would be useless to wake it in most cases
as for the perko switch yes that will work it you switch to 1 and 2 /both in parallel, some people just use a on off switch and a common ground between the batteries. on is parallel and off is isolated

If your jumper battery is not a start battery dont start you big motor before you turn the perko back off.

Ive had to wake my start battery a few times and when its woke its always started my 4s.
