Whether you refer to them as go-boxes, go-kits, or rapid deployment kits, powering a transportable ham shack is of utmost importance.

While both battery chemistry types have much to recommend them in other uses, the go-box imposes certain requirements and operating conditions that many consider unique.

Some still insist that Sealed Lead Acid is better for a generic go-box than any lithium chemistry, but I haven't found much reason to back that up.

What about the go-box requirements or operating environment might suggest that SLA might be a better choice than a lithium chemistry battery?

  • $\begingroup$ This is pretty subjective. "Some" still insist? Who? Is this the kind of go-box you keep under the bed in case of zombie uprising, or the kind you keep in your truck, in case you are called for a search-and-rescue mission? There are a lot of requirements that aren't here, and a lot of opinion relevant to the right answer. $\endgroup$ Commented Jan 22, 2014 at 22:41

    $\begingroup$ Well I think that one big plus point for SLA is that they can be recharged more or less safely by car battery chargers which I believe are more common than lithium battery chargers. Furthermore, in case of emergency, SLA can be more easily replaced by a battery from more or less any nearby car (well if it's 12 V), while lithium batteries usually have different voltages than lead-acid batteries. $\endgroup$

If near freezing or colder conditions is one of your possible operating environments, then SLA cells can still be (re)charged at slightly lower temperatures than lithium chemistry cells.


SLA cells are dead easy to recharge, improvising a charger may be as easy as a set of jumper cables. Lithium ion's require active charging circuitry and the failure mode can be catastrophic.

That said, the new LiFePO₄ batteries seem to combine the best of both, energy density comparable to lithium ion with the saftey and easy charging of lead acid.
