update: I tested charging/discharging simultaneously, it worked well 348w in, 230w out, not bad, I will server my needs for Sienna, it is unseasonably warm in MI this spring, so I have not had a need to use this yet.

FYI: look at the size CAREFULLY pls, they are all not 1:1 replacement for some Lead Acid batts, make sure your space will fit them.

zero, I bought the mephr whatever it is called with bluetooth bms from amazon for 180$ Next time it drops to $130s, I might get 3 more to make a 48v in series. with the one battery with bluetooth and 3 regular in series I can monitor the current and level of charge for cheap for the 48v system

Agree, sub zero BATT temps are no good. My use case: Batts stored in heated garage, stays at 50F in peak winter, Van driven with heat on to fishing destination, batts remain in the van at room temp once at fishing spot, the heat from batts will run continuously for say 8 to 10 hours. So the...

Sorry, I should have stated, they call have the same specs on bluetti's FAQ. Good Point, I have not tested mine at 32 F, You sure? from I what I have read, the battery makes spec out this, A123 for example were made for the DOD and have better ranges :) yes, not knowing what the hardware is...

Op, 1. Please look up the alternator output curve, most alternators output is low at low rpm or idle. 2. Look into HIGH IDLE switch or ECU option 3. Test the same and have someone sit at the helm and raise the idle to 1300 rpm and see how the unit does, 4. Gun your alternator with a laser...

FYI: BOTH Bluetti's have the same LFE chemistry they have is temp range on the website: Q10: Can I use or charge AC180 in sub-zero temperatures? A: You can use the AC180 to power your devices in cold weather, but please avoid recharging it below freezing. The operating temperature ranges for...

Thanks!

Dave, where did you find that shiny insulation? I bought the one from lowes and it is the bubble type, also which velco is that, looks like it was strong adhesive on it, nice, I like it. I am going to double tint the windows and then put that shiny insulation but I will spray paint it black and...

Congrats, I raise my mug of Chai with lotsa half and half!

Dave, No solar panels, I will be using the bluetti with external battery plugged in into the solar input. I have an 8KW battery bank and adding another 3kw battery if needed. In both the sienna and transit: Primary source of heat, if I want to sit in my jam jams, will be to idle the vehicle...

Op, not sure if you looked into the bluetti's, if I use my transit as an office on wheels and I use a bluetti AC200P with cheap external connected to it to extend the run time. Maybe some to consider... 4 DC House 12v 100AH batteries in series or 2s4p tied to a bluetti will give you around...

Dave, you correct, external batts will feed into solar input for the Blue I am using 10 awg wire, the run is about 4 ft max. I will look for a 20A~25A CB, The sienna is tiny compared to my 350 Transit Van (extra high), so a little bit of heat will go a long way. I will have air gap insulation...

Op, I would get a 36v charger, if you need a waterproof one, you can get a meanwell hlg-xxx-36A else, my go to charger is a meanwell NPB-450-48 to monitor current/voltage you can a victron external monitor. I opt'd to get a 12v with bluetooth bms, and one in a chain, just one BT battery will...

yes, free shipping, $133 plus tax, it sold out with a few hours in the morning,

I have been thinking of adding a rocket launcher and a small 200w solar panel, it would serve has shade in summer and charging :) solar panel > victron solar smart solar controller > batts you can control/watch it from you phone.

op, I broke down and bought a bluetti ac180p to charge my trolling batts, while tidy up and pack stuff away, the bluetti charges the battery. I also have a minnota alternator charger in my little tin boat, it charges the trolling batts while I motor out to my super secret honey hole.

Good Monday Morning from West Michigan, Grandma and I are planning on hitting the piers for some spring fishing, I bought an old (2013) sienna awd to fish. I want to run a 300w small heater in the van for heat. The setup will be simple Heater > Bluetti Bluetti Solar input > 36/48v...

Get em boyz/girlz https://www.ebay.com/itm/145441548113 I watch a guy take one apart on youtube, that one had prismatic cells, I wrote to the seller, asking to confirm type of cell, the guy refused to answer the question. Sale is back, $133 is gone but still good price

Any of them with In-Rush current protection built in?

There seems to be an issue with JK? next video show a fix for it. FYI:

I have the same problem with my boat and van, Solar panel (50w) > charge controller > battery Solar panel on roof using VHB tape > run cable down rear door half way down the side, make a drip loop.

Curt thks, nice job in fitting it in the box. if you ever open up the ps, pls take some pics of the inside and post.

Struc: Can you open it up and post pics of the inside pls? the price is pretty good for the power output.

Here is the response from Jag35: Thx for your email. You purchased "untested" packs. These packs were advertised as "reclaimed", "these packs are untested", and "These items are sold for DIY and Second Life purposes". There are no guarantees made or implied of full 9ah performance. Have a nice...

hmm, the pack has a working bms, I am expecting all the cells to be working, else the 9ah rating is void.

I have a bunch of 50 bmg and other sized ammo cans, I buy a bunch from ammo from CMP store at Port Clinton, maybe I can find a bigger mortar case or something?

I might have to call my ex to help me lift this one, lol

good question, the pack produced 2ah

Agree, yes, I have glands and terminals, so I need a metal box of like this, I looked at amazon and could not a box as big as this. I could always fab but trying to avoid that,

The bms cut out due to low voltage, so pretty much zero volts at the output

Saw this battery, nice case, any clue where I can get one? I love the nice clean shiny look!

deleted wrong thread, sorry

All I can say is OUCH! I bought the r7 ebike battery cuz it came in a "cute" downtube enclosure. It is rated at 9ah at 36v. Batteries were heaters, I charged them in stages and let them sit, charged them again.... fully charged them and then connected them to my capacity meter, walked away...
