Just ordered two DrPrepare 100mah for $209 each delivered these are the new ones they redid them with better BMS and low temp charging protection and ten year supposedly warranty. At this price for my trolling motor cannot hardly go wrong. I was considering a change to LifePO4`s. I had picked up a NOCO Genius 3X10 charger in preparation at a cheap price. Going to be hard to give up my 23 year old Dual Pro 3X10 it has never gave me a lick of trouble it just worked.
