Absolutely no reason to entertain NiCad batteries when NiMH will do.
Besides, most (no-mechanical) Li-Ion hazards are related to the charging circuits and not the battery itself (knowing its limitations).
Why would anyone consider NiCad over NiMH ,,, in any environment?
I'd rather go back to lead acid. NiCads and MiMH can both go into an overcharged/overdrawn/overheated state that can lead to venting or fire. Lead acid generally do not (without actually throwing them into a fire).
Also, the nice thing about lead acid is they tend to fail slowly and have a more measurable output drop (they give warning when they are getting weak while NiCads and NiMHs do not).
