Check
@Mooch's blog for his latest charts and rest results. Any battery with 20A or higher CDR should be able to handle up to 120 watts in pairs, easily. If you want to take it up to the full 220 watts you're looking at around 40A at low charge; no battery has a CDR this high and precious few even have MVA's that high. (MVA is "max vaping amps," mooch's own "safety limit." CDR is more about keeping the battery in good health and, as such, has a significant "safety" margin sort of built right in. Habitually driving a battery at max vaping amps is not recommended, as it is hard on the battery and will shorten their life significantly, but it
probably won't end in catastrophic failure.)
