Weise lithium batteries

[Jig Man]

Anyone know anything about them?

No experience with Weise. The brand advertises being lighter weight and compared to Iconic 12V 50AH @ 24 lbs the Weise is 17 lbs. my guess the weight savings is due to thin light case and less internal materials. Weise claims 8,000 cycles, but the case list 2,000 cycles and doesn’t recommend TM use, sonar is OK.

Will Prowse gave them a great review on his YouTube channel and then looked at them again 18 months later and they were completely different internally.  I think that’s probably true with all of the cheap brands.  They buy a batch of them from the manufacturer and the next batch may be from a different manufacturer.  That said they all get pretty good reviews on Amazon.   For most consumers you buy it and it works. Some have slightly better build quality which might translate into slightly better reliability.  I wouldn’t put much stock in long warranty.  I really doubt any of these brands will be around in 10 years.

I think that you mean Weize and not WeiSe.

 

Anyway, I have a 100Ah that I use with my Old Town Autopilot 120 and it has been great. 

 

For tournament fishing I may even keep a second one on board so I can cover more water at speed. The specs say it weighs only 29 pounds.

I've got a Weize 50Ah lithium and use it for the trolling motor (MK Endura C2 30) on my kayak.  I've had it about a year and a half now and have no complaints.  Well, I did replace the stock bolts on the top with SS wingnuts to make hooking it up easier.  I guess it would have been nice if it came with those.  But that's about the worst thing I can say about it.  

 

The 8,000 cycle rating is for draining to 50%.  The 2,000 cycle rating is for draining to 0%.  So in theory, under normal use you'll likely land somewhere in between.  But who knows where they dig up these numbers and how accurate they truly are? 

 

The 50Ah sized battery has a max continuous discharge of 50 amps, so it should be fine with smaller trolling motors.  But if you're using something like a 55lb thrust motor, it's going to want to pull around 52 amps at full speed, which is over the limit for the battery and will probably cause it to shut down.  Which is probably why it's not recommended for trolling motors in general.  The 100Ah version is rated up to 100 amps of continuous discharge, so it should cover all trolling motors without issue.
