I will be replacing my battery sooner than later. I had searched high and low for a good LifePo4 replacement that meets my needs. There are a few but, there will be more in a few years time.
My only issues is the useless jump start reserve that many are pushing as a bonus. IMO, LifePo4 does not need such a thing. Anyway there are some things that irritate me about lack of battery specs from the many manufacturers.
I have come to a rule of thumb with LifePo4 batteries... look for dual purpose battery or start / deep cycle type. If not given in the battery info, look at CCA and AH. If a LifePo4 battery lists a CCA above 1000. Most likely it can deliver start current for winching without tripping current limiting protection. As for AH, almost all 80AH and higher don't supply high current well enough for winching or are limited to small engines. Jeepers seem to want high current and high high capacity, which goes back to why place a reserve capacity for jump starts? Just a thought, no burning question about it. Prolly is that you are enabling a circuit to allow high current discharge for producing its advertized CCA. So lifting the hood will be required to winch. Not a problem unless it's impossible to move to both sides to unlatch without risking injury. Well, maybe about sure footedness?
So my quandary is how the protection circuit is designed. Some report 1% a month internal depletion to 1% a year. Usually the ones lacking good CCA have the lower internal depletion. Seems like having a jump start feature allows for a lower internal depletion rate. Only a few offer Bluetooth remote jump start activation.
There is one Chinese brand that boasts dual purpose and is cost effective, but it seems to be only in one type of case format, which has reversed posts. Redoing a JL battery wiring for a different case is not what most would do. But it would have been nice to give it a try, as the reviews seemed good from US buyers.
But then again going for cost savings... you will find many require a DC to DC LifePo4 charger to be installed to your charging system.
So far only 3 LifePo4 batteries will fit my needs, yet $$$$$ and the jump start feature I am trying to ignore makes me want to wait it out for better options in the near future.
The closer I get to need of replacement the more I am being pushed to AGM. There is no perfect LifePo4 battery as a drop in replacement for a Jeepers needs.
Just remembered.... I posted a link some time ago, about two good drop in LifePo4 battery options. One is for below zero use. Rather have a heated battery than a hardly ever used jump start reserve.
Well only time will tell which direction I go.. Tick tock, tick tock, tick tock...
