Our 12v 200Ah LiFePO4 Battery is waterproof, and the IP level is IP65.

This IP grade indicates that the product will not enter the water when you put it outside on at rainy day. In normal rain, the water will not affect the product;

However the battery terminal should not contact with water during use, otherwise it may cause a short circuit of the battery.

1. Initial Activation:

Before deploying the 12V 200Ah LiFePO4 Battery for the first time, you'll need to activate it. This can be done by subjecting the battery to a charge or discharge current greater than 1 ampere.
2. Terminal Voltage Validation:

After the activation, measure the terminal voltage of the battery to confirm that it meets the required specifications.
3. Periods of Extended Storage:

If you plan to store the 12V 200Ah LiFePO4 Battery for an extended period, it's advisable to disconnect it from the system. This precaution is taken to preserve the battery's condition.
4. Automatic Shelf Mode:

The battery will automatically enter what is known as "shelf mode" after 24 hours. In this mode, the battery exhibits a low self-discharge rate and can retain its charge over an extended duration.

To ensure optimal performance and longevity for your Motawill 12V 200Ah LiFePO4 Battery, we recommend using a charger that meets the following specifications:

1. Charging Voltage: It is essential to use a charger that provides a charging voltage within the range of 14.2V to 14.6V.

2. Charging Current: The recommended charging current can be selected based on your specific requirements:

20A (0.2C): This charging rate will fully charge the battery in approximately 5 hours, bringing it to 100% capacity.
50A (0.5C): Opting for this charging rate will get the battery to around 97% capacity in roughly 2 hours.

We strongly advise against combining a 12V 200Ah LiFePO4 Battery with a lead acid battery pack. Such a configuration may lead to damage to the batteries and should be avoided.

When wiring or connecting batteries, it is essential to match batteries that are of the same type (in this case, lithium), possess the same capacity in Ampere-hours (Ah), have the same voltage (V), and are from the same brand. Mixing different types of batteries, especially lithium and lead acid, can result in operational issues and potential harm to the batteries.

Certainly, You Can Charge 12V 200Ah LiFePO4 Battery with Solar Panels

1. Series and Parallel Connectivity: Our 12v 200Ah LiFePO4 Battery are designed to support both series and parallel connections, allowing for flexibility in configuration.

2. Maximum Configuration: With this in mind, you can expand your battery system to accommodate up to 16 batteries. This can be achieved by connecting them in sets of 4 in series and 4 in parallel.

Connecting batteries with different capacities, such as a 12V 200Ah LiFePO4 Battery and a 12V 100Ah Battery, is not recommended for two primary reasons:

1. Current Discrepancy: When batteries with different capacities are connected in parallel, the larger-capacity battery (200Ah) will contribute double the current compared to the smaller-capacity battery (100Ah) during both charging and discharging. This mismatch can lead to imbalanced performance and potential issues.

2. Impedance Differences: Batteries often have varying internal impedances. When batteries with differing impedances are linked in parallel, it can result in long-term strain on the Battery Management System (BMS) and may lead to damage over time.

To ensure the safe and efficient operation of your battery system, it's advisable to use batteries with the same voltage and capacity when connecting them in parallel.

It is recommended to store Motawill 12v 200Ah LiFePO4 Battery at 50% state of charge (SOC). If the batteries are stored for long periods, cycle the batteries at least every 6 months. Recommended storage environment: 10℃~35℃ (50℉~95℉),45%RH~75%RH

  1. AI Lai to

    I used my battery for the first time after receiving it about a month ago. I used it for a weekend of camping in Jasper where night time temperatures were around 5C or less.
    When I connected the battery and checked my RV monitor it said “Charging” which I found unusual as normally this is only lit up when plugged in or on a generator. I checked again that evening when the furnace was running and a couple of lights (LED bulbs) were on. It was now displaying “Good” which is what I normally see with the four 6 Volt batteries that I previously used. When the furnace shut off it went back to charging. This didn’t change after three nights of camping. I did use a couple of 100 watt solar panels to charge during the day but I didn’t really babysit them and only turned them a couple of times. I just used my multimeter to check the battery and it’s showing 13.05 volts, I started with 13.65
    Needless to say I’m impressed with the performance of the battery. I do wonder about the performance over time but so far I’m very happy. I did remove the battery and will store it inside.
    Last year I bought a 100Ah battery from this company and used it for 6 nights last summer to run my CPAP machine. It’s performance hasn’t changed at all from last year. I checked it after three nights of use this past trip and it’s at 13.10 volts. I had it hooked to a 100 watt solar panel as well.
    It’s definitely a change from the old lead acid batteries but so far I’m very impressed. So much easier to move around. I still have two 6 volts lead acid batteries so I installed a switch to isolate the two battery systems from each other.

    I highly recommend the company and the batteries.
