【Like New】Redodo 12V 230Ah LiFePO4 Battery | 2.944kWh & 1.92kW

Hi, our 12V(12.8V) 100Ah LiFePO4 battery built-in 100A BMS, which could support 100A max. continuous charge/discharge current, 1280W max. load power, and 1280Wh max. energy. In general, the power of the inverter depends on the power of your load. Most of our customers will use 1000W PSW inverter for one of our 12V(12.8V) 100Ah LiFePO4 batteries. To help you analyze and optimize your battery system precisely, we welcome you to contact us at service@redodopower.com, and we will help you with an in-depth analysis according to your detailed information.

Hi, our 12V(12.8V) 100Ah LiFePO4 battery built-in 100A BMS, which could support 100A max. continuous charge/discharge current, 1280W max. load power, and 1280Wh max. energy. In general, the power of the inverter depends on your power of load. A 2200W PSW inverter will also work with one 12V(12.8V) 100Ah LiFePO4 battery, and it still has room to extend by adding batteries if there are more appliances in. However, it is still depends on the power of your load.

Hi, many of our customers use 2 of Redodo 12V(12.8V) 100Ah LiFePO4 batteries connecting in series for their 24V trolling motor, and it works well. But it is also depends on the power of the trolling motor. One of our Redodo 12V 100Ah LiFePO4 batteries could support 100A max. continuous charge/discharge current, 1280W max. load power, and 1280Wh max. energy. Connecting two of Redodo 12V 100Ah LiFePO4 batteries in series will build a 24V(25.6V) 100Ah battery system, which could support 100A max. continuous charge/discharge current, 2560W max. load power, and 2560Wh max. energy. To help you analyze and solve your question about the batteries more specifically, we welcome you to contact us on service@redodopower.com, and we will help you with an in-depth analysis according to your detailed information. 

Dear Customer, 1)Yes, 1 charger could works for 2pcs Redodo 12V(12.8V) 100Ah LiFePO4 batteries which connected in series. One 12V 100Ah LiFePO4 battery built-in 100A BMS, which could support 100A max. continuous charge/discharge current, 1280W max. continuous load power, and 1280Wh max. energy. Connected 2pcs of those 100Ah batteries in series will build a 24V(25.6V) 100Ah battery system, which could support 100A max. continuous charge/discharge current, 2560W max. continuous load power, and 2560Wh max. energy. Regarding the charger for the 24V 100Ah battery system, we recommend a dedicated LiFePO4 battery charger, the DC charging voltage should be between 28.4V~29.2V and charging current less than 100A (usually, we recommend the current of 0.2C, which means 20A, and it will take around 5hrs to fully charge the battery system). 2)Here are two steps are necessary in order to reduce the voltage difference between batteries before connection, and through these, the battery system can perform the best of it in series or/ and in parallel. Step① fully charge your batteries separately. Step② connect your batteries one by one in parallel, and leave them together for 12~24hrs. And then, you can connect your batteries in series or/ and in parallel to build your own battery system. BTW, for charging one 12V 100Ah LiFePO4 battery, we recommend a dedicated LiFePO4 battery charger, the DC charging voltage should be between 14.2V~14.6V and charging current less than 100A. To help you analyze and optimize your battery system precisely, we welcome you to contact us on service@redodopower.com, and we will help you with an in-depth analysis according to your detailed information. 

Hi, for safety reasons, we don’t suggest connecting 5 or 6 pieces of the Redodo 100Ah batteries in series. Our 12V 100Ah LiFePO4 battery supports up to 4 identical batteries for up to: 48V 100Ah battery system (in series) 12V 400Ah battery system (in parallel) And we recommend connecting MAX. 16pcs of Redodo 12V(12.8V) 100Ah LiFePO4 batteries in 4P 4S to build a 48V(51.2V) 400Ah battery system(“P” refers to parallel, “S” refers to series). To help you analyze and solve your question about the battery connections more specifically, we welcome you to contact us at service@redodopower.com, and we will help you with an in-depth analysis according to your detailed information. 

Hi, at the beginning, we had set up the low temperature cut-off function for Redodo 100Ah LiFePO4 battery, but later many customers responded that they also want to discharge it under 32°F/0°C. After careful research, our team has decided to block this function. Some of our customers who live in the cold areas who are happy to use our batteries too, because it can discharge well and their loads can work under low temperature. If they need to charge the battery below 32°F/0°C , they told us that they choose a dedicated LiFePO4 battery charger with a low-temp cut-off function, or take the batteries to the house where the temperature is higher than 32°F/0°C. We will have the LiFePO4 batteries that have low temperature protection in the near future. 

Hi, usually, you can leave LiFePO4 battery connected to charger after it has been fully charged for a while if your battery charger has automatic power off function. Redodo LiFePO4 battery also has over-charging protection too. But for the safety reasons, we suggest that disconnect the battery with the charger once it is full charged.

No, we do not suggest you to connect 12v 200ah battery to the battery system of 2*12V 100Ah battery. Although Redodo 12V 100Ah LiFePO4 battery and Redodo 12V 200Ah LiFePO4 battery have built-in 100A BMS, the capacities of two battery models are different. To connect in series or /and parallel, batteries should meet the below conditions: a. identical batteries with the same battery capacity (Ah) and BMS (A); b. from the same brand (as lithium battery from different brands has their special BMS); c. purchased in near time (within one month) So if you want to expand your battery system, we suggest you to add 2*12V 100Ah battery.

Hi, we do not recommend to connected the Redodo 12V 100Ah battery and 200Ah battery together. Here are two main reasons why we don't suggest connecting batteries with different capacities: 1) After parallel connection of batteries with different capacities, the current of 200Ah is twice as large as that of 100Ah when charging/discharging at the same time. 2) The internal resistance of the 200Ah battery is 2-4mΩ, and that of the 100Ah battery is 7-9mΩ. When the batteries with different impedances are connected in parallel, it is possible to damage BMS after long-term use. To connect in series or/ and in parallel, batteries should meet below conditions: a: the same battery capacity(Ah) and same BMS b: from same brand(as lithium battery from different brands has their special BMS) c: purchased in near time(within one month) d: from same types of battery

Hi, we suggest that you place Redodo 12V(12.8V) 100Ah LiFePO4 battery with the terminal bolts upward. If you have more than one Redodo 100Ah LiFePO4 battery, please avoid their post bolts having direct contact when mounting them. To help you analyze and solve your question about the batteries more specifically, we welcome you to contact us at service@redodopower.com, and we will help you with an in-depth analysis according to your detailed information. 

Hi, Redodo 12V 100Ah LiFePO4 battery have cells which get certificate from UL and the protection class is IP65 and the battery quality is Grade-A.

Hi, 1)We don’t suggest that to connect the Redodo 12V(12.8V) 100Ah LiFePO4 batteries with any lead-acid batteries because they are totally different: 1. The LiFePO4 batteries and the lead-acid batteries own different charge/discharge modes; 2. The voltages of the LiFePO4 batteries and the lead-acid batteries are different(even if they are written in 12V); 3. The LiFePO4 batteries are built in BMS while the lead-acid batteries are not. 2)To connect in series or/ and in parallel, batteries should meet the below conditions: a: the same battery capacity(Ah) and same BMS b: from the same brand(as lithium battery from different brands has their special BMS) c: purchased in near time(within one month) d: from same types of battery To help you analyze and solve your question about the battery connection more specifically, we welcome you to contact us on service@redodopower.com, and we will help you with an in-depth analysis according to your detailed information. 

Hi, Yes, for Redodo 12V(12.8V) 100Ah LiFePO4 battery, you can connect 6 batteries to make a 3P2S (P refers to Parallel and S refers to Series) battery system of 24V(25.6V) 300Ah. One Redodo 12V 100Ah LiFePO4 battery built-in 100A BMS, which could support 100A max. continuous charge/discharge current, 1280W max. continuous load power, and has max. 1280Wh energy. The 3P2S battery system of 24V(25.6V) 300Ah could support 300A max. continuous charge/discharge current, 7680W max. continuous load power, and has max. 7680Wh energy.
