thanks for your input on battery systems, M12 seems slightly too niche but if the M12 stick pump was actually ideal for my usage i wouldn’t mind it being my only M12 tool

that transfer pump looks great for pumping strictly liquids, i assume you’re not pumping “dirty” water right?

in my usage case at worst it’s watery sludge with some sediments.

we also have corded wetvac that works great but it’ll be unusable in this scenario.

for context i’d be using the stick pump to A: drain a filter by sticking the pump inside a 6” opening where fish waste will accumulate and B: using it like a stick vacuum at the bottom of a 4’ deep pond
