    GOOD BUY? Lithium 12.8V 200ah Battery BMS $899.

    I can't afford a Battleborn battery or others of the same dollars but this one really caught my eye.
    Now I know it's not the best but for someone just starting out this would go a long way with my limited budget $$ in getting started with a Lithium battery setup.
    Can you give me your opinion on buying this 12.8V 200ah Battery BMS LifePO4 Deep Cycle Solar LED Display Marine Solar RV for $899.

    Here is some basic information:
    * 12V 200Ah Lithium Battery pack is made of 2parallel 4 pcs of 200000mAh Lithium Cells
    * Rated Voltage:12.8V
    * Rated Capacity (0.2C): 200Ah / 2560Wh
    * Maximum Continuous Discharge Current: 100A
    * Max. discharging current: 200Amp(Duration: less than 5 seconds)
    * Maximum Charging Current:100A
    * Over Charging Protection Voltage: 14.6V
    * Cycle Life: 2000 cycles 100% DOD,Depth of Discharge (DoD),up to 5000 cycles at 80% DoD
    * Charging time: Approximately 6 hours
    * Operating temperatures: Charge 0°C~50°C,
    * Discharge -20°C~60°C, Storage -20°C~50°C
    * Impedance: ≤ 15mΩ
    * Cut-off voltage: 10V
    * Depth of Discharge (DoD): 100%
    * Output: 14.4 - 14.6V; Input:110v/AC/50HZ
    * Standard charge current: 20A
    * Max continuous charge current: 50A

    Here is the web link to the battery:

    I've never heard of BtrPower. I looked at their website and it's apparent somebody threw it together quickly (lots of typos). One year warranty is the lowest I've heard of (others have 10 years to life). I personally wouldn't buy a LiFePO4 battery unless somebody had done a tear down review and tested it. I'd want to see the quality of the wires/lugs/cells/BMS/case, etc. I'd also want to see a capacity test and also confirm it has high/low temp cutoffs.

    If I couldn't afford Battleborn, I'd consider something like the Lion Energy UT1300 which are on sale right now at Costco for $1,399 for two.

    Do you like the Dual Case (2 in one case) or 2 separate batteries for RV use?

    I prefer fewer connections between batteries for RV use. But that's just me. I'm moving from two Lion Energy UT1300's to two of the new 270ah Battleborn GC3 batteries. The downside of going with a single, larger battery is if it fails, you're SOL.

    Did you have any problems with vibrations on your RV with the Lion batteries? The video said that vibration can cause problems for the Lion battery.

    No, but I've never liked the post design. You can tighten the lugs but when I do it, I cringe wondering if the nut in the case will strip out. So they are snug but not really as tight as I'd like. That's one thing I really like about the BB batteries. The posts are designed such that you can crank down the lugs with zero chance of damaging the battery.

    Will's concern with vibration in the Lion Energy battery holds true across all the cheaper brands. The construction just isn't the same as higher quality batteries. He has done several battery tear downs where he cuts open the case and dismantles and tests everything. The build quality and components (wiring, lugs, crimps, etc) used in some of the cheap batteries is scary.

    I’m in agreement with your assessment of Li fly by night companies with unproven quality control.

    He does have an alternative. Instead of the Lion Energy or any lithium we have Oasis Firefly Carbon Foam AGM. Not at all like any other AGM with lots of similar performance properties of Battleborn. You can draw the down to 20% easily and without penalizing cyles. Can get 3000 cycles. No special battery management system. No danger in an accident of a lithium fire which could be spectacular. ( First responders get special training when appearing at an accident with lithium battery powered cars) the cost is just north of $500. 6 year warranty

    You are thinking of lithium ion, not Lithium Iron Phosphate (LFP). The FAA has done fire tests and concluded that LFP batteries are dramatically less likely to become a fire hazard than lithium ion.

    the cost is just north of $500.
    Best I can find is just under $700 including shipping. And it's still really heavy, and has less capacity than a Battle Born LFP (which includes shipping in the advertised price).

    6 year warranty
    Just over half as long as the warranty on a Battle Born, which is only $200 more (and has slightly more capacity).

    Also worth noting is that the carbon foam battery still has problems with relatively high self-discharge rates, and it has a 'memory' and will lose capacity over time until you draw it all the way down and fast charge it back to full. LFP batteries don't have this problem.

    I think the carbon foam battery is a very interesting competitor to AGM, but it's overpriced by about 2x.

    It's especially bad if you compare it to a budget LFP like Ampere Time, which are built pretty well but cost $500 for 100 Ah or $800 for 200 Ah, and still have all the usual LFP benefits.

    I'm intrigued. Did you have to replace the factory installed converter/charger?
    Thanks.

    Since I'm sooooo new at this. I'm really looking for a entry level on this whole thing.
    If its not too much to ask could you give me a $$ breakout on what a inexpensive dual lithium batteries, inverter/charger and monitor would cost?
    Then in a 5 years I would update the system for more serious dry camping. As it is now me and the wife will only be dry camping a 1-3 days max.
    Thanks on behalf of all us Newbies.
