Complete newbie who's been playing with the Mauler for a couple of weeks now. I've found that the Nimh batteries they came with only last around 10 minutes after charging for the recommended 3 hours. Is that expected? Seems a bit low to me. Want to upgrade to a lipo battery. Some questions: 1. Are lipo safe sacks a thing? Are lipo's that dangerous in the RC world? https://www.modelsport.co.uk/product/overlander-lipo-safe-sack-38313 2. Saw these two batteries in the thread 5000mAHr and 4000mAHr. The square one seems to make better use of the available space, so seems to be the one to get for a longer runtime. How long can I expect these to last? Is Voltz a reputable brand? https://www.modelsport.co.uk/product/voltz-5000mah-2s-74v-50c-hardcase-lipo-stick-battery-pack-442614 https://www.modelsport.co.uk/product/core-rc-4000mahr-74v-3060c-2s-lipo-388538 3. Considering this charger unless there are better recommendations. https://www.modelsport.co.uk/product/skyrc-s65-ac-charger-65w-438918 https://www.modelsport.co.uk/product/skyrc-charging-cable-xt60-female-to-deans-male-445872
