You can charge/jump lithium batteries with just some basic rules, all aimed at not putting too much current through the battery:
1.) Don't use a battery charger where you can't turn off the battery repair/de-sulfication process. This basically shoves a bunch of current into the battery to break off the crystals on the cells, which is BAD to do on a lithium battery, but GOOD to do on a lead acid.
2.) Don't leave a charger on that will charge it without shut-off, the battery will over-charge
3.) If jumping, don't use an aggressive jump box, just jump from a plain battery.
Also, never let lithium batteries get too low. Once they reach a really low voltage, even once, they won't take a charge ever again.
