Bought a Powersonic PS-12350 NB for my canoe. Weighs 25#. Is an AGM battery that does not spill. Paid $106 delivered from Amazon.ca in July.
Use a 30# Minn kota and ran it on speed 5 for 75 minutes for about 7km down a lake (2 in canoe and fishing gear). Speed was 6.2km/hr at the start,
and 4.6km/hr at the end. Use speeds 2-3 when moving around lakes Bass fishing and it lasts all day. My 5 year old portable fishfinder came with a
Powersonic battery and it is still going strong, thus the Powersonic purchase for the trolling motor. Would not use a motor larger than 30# with this
(small) battery.
