About this item

  • 【Upgraded BMS Circuit】 Equipped with seven pairs of Mosfet and two pairs of XT90 are designed to allow a peak current of 150A to pass through, providing emergency charging and discharging option for you(overcharge protection triggered at 1C-rate, and over-discharge protection at 1.3C-rate). The high-precision BMS design offers over 20 protections and warnings, and the heat dissipation area increased by 50% compared to others on the market to maximize the safety of your off-grid use.
  • 【Uncompromising Quality】 The high-quality pouch cells surpass severe high temperature and puncture tests to avoid fire or explosion. This battery has also passed international standards and quality requirements, such as UL1642(battery cell), UL1973, MSDS, UN38.3, FCC, CE, UKCA, PSE, and MIC. Offer over ten years of lifespan with more than 4,000 cycles (80% DOD).
  • 【Activation Switch】 With the activation switch cable, you can turn on or off multiple batteries in parallel to ensure the safety of installation and use. The open-circuit voltage is extremely low when the BMS is in the hibernate mode, which minimizes battery over-discharge when connected to appliances for a long time, ensuring the health of your batteries and extending their service life.
  • 【Auto-balancing Function】 Easily connect multiple batteries in parallel(up to 8)with the auto-balancing function, improving the average charging efficiency for your batteries in the long term.
  • 【Real-time Monitoring】 You can connect the battery monitor directly via CAT cable without purchasing an additional coulometer. You can also use the BT-2 Bluetooth module to monitor multiple battery states in real time with the DC HOME app. If you have multiple Renogy devices with communication port, we recommend adding Renogy ONE M1 to achieve smart energy monitoring with intuitive visuals and real-time data.

Notes:

● Please secure all cable connections to the proper specification in order to ensure good connection between the cable lugs and the terminals. Over-tightening cable connections can cause terminal breakage and loose cable connections can cause terminal meltdown or fire.

● DO NOT string the battery in series. ONLY connect batteries of the same manufacturer and model in parallel.

● Please avoid too high a voltage difference between paralleled batteries, despite the auto-balancing function, to avoid triggering the over-current protection.

Product Description

    Bought 4 Renogy 100 ah, 12v Smart batteries in early 2020. 4 years later I’m surprised to see the recent bad reviews. Still using the batteries today without incident. Hold a charge “forever”. Most importantly they hold a large amount of charge available for use. Interested in more of these for another project. Would be nice if Renogy or Amazon would respond to the bad reviews.

    Reviewed in Germany on November 11, 2022
    Ich habe die Batterie am 27.11.21 durch Amazon Bestellt und habe sie nun Ausführlich im Wohnmobil getestet.

    Ich muss sagen das die Batterie mich bis jetzt nicht überzeugt hat mir scheint das die AGM Blei Batterie auch 100Ah länger halt auls diese Lipo Batterie sie maag wohl ok sein aber mehr auch nicht erneut Bestellen würde ich sie nicht mehr da sie das Geld nicht Wert ist lieber 10kg mehr aber es hält diese geht zu schnell leer und ihrgend wann fällt sie unter 12volt und die Spannung fällt auf 3volt runter fallt obwohl ich nur immer den LapTop Auflade und zusätzlich eine 200Wp Solar Anlage habe und die Batterie knapp 1 woche hält finde ich das eune Schwach Leistung daher nur 2 Sterne Ende der Misserablen Story.
