Our dealer has been in contact with you all.  They stated that Malibu has de-featured all newer models to not have a proper EQ.  This stinks....

My 2023 M220 has the EQ feature. I wonder why some models have it and some don’t. 

Ok, thanks @justgary. Boats going into the shop today and we’ll see later today.

 Be cautious on lifepo4.

there is a guy on YT that opens them up many don’t actually have low temp charging protection thus they will get damaged at below 32F. Some are ok and are getting better for sure

U also need to get the larger sizes with a minimum 100A BMS to handle most cable lifts that use a winch motor however hydraulic lifts all use 150/230A so you will blow the BMS or it will stop outputting and you would need two in parallel and if you have 24v hydraulic then u need at least 4 batteries sometimes 6 on monster lifts $$$$

also These are all honeycomb structures so if you get a bad cell you avg joe would never know they loss 25% capacity. 
 

For boat lifts $90 Walmart marine batteries is the max I’d spend unless you want AGM then go to Amazon and grab a Weiss or mighty max, the solar will also recharge the AGM about 1.5-2* faster so it’s like having a larger solar/faster recovery and in most cases you can downgrade one battery size with AGMa to have a lighter weight battery in the lift. Example I went from group 24 deep cycle to smaller AGM 12v-55A wheel chair size and works great and are smaller and lighter!

LiFePO4 will get damaged with significant charge current when below about 32F, but I seriously doubt the lift will be used then.  Note that discharge is OK when cold.  Since the battery will most likely be full when it gets cold, charge current will be very low.

Yes, quality of the BMS matters.  JBD makes 200A and 300A versions with temperature control (e.g. to run a heater blanket when the temperature drops, if desired). 

LiFePO4 will allow full discharge, where lead acid is considered fully discharged at 50%.  In other words, you can get about 50Ah from your 100Ah lead acid, but you can get 100Ah from a 100Ah lithium.  Lithium also has a much lower internal resistance, so the voltage doesn't sag much at all under load. 

The honeycomb comment/bad cell advice is wrong.  You will definitely know if you have a bad cell because the battery voltage will drop, just like it will with lead acid.  Besides, the BMS will report actual cell voltages to you if you care to see them.

If choosing lead acid, I would always go with wet cells over AGM in any non-portable situation.  The ability to check specific gravity and add water are definitely a plus when trying to keep the batteries around for a long time.

As always, do your homework before you buy.

1) No front ballast. I just don’t understand this design decision. Why do we need a walk thru bow? It’s not a Bayliner. Nobody uses these boats like that. As a result, the nose runs a little high (with full ballast and wedge) for such a big, long boat. And to dial the wave in I found we needed to add lead up there anyway. It makes no sense to me that Malibu would change the ballast recipe on just ONE boat… 

This is interesting to me / us.  We love the concept of a walk thru.  In fact jealous of the tow boats with it.  But wouldn't want to compromise with no front ballast.

I ordered from Amazon. Same Quicksilver kit but 50 dollars cheaper than Bakes Marine. Haven't put on yet given my code dropped this week, but expecting it to come back soon knowing my luck.

Holy crap.  $111 for a cap and rotor?  This is the Accel stuff on Amazon
