About Our User-Friendly BMS Smart App
BLUETOOTH PHONE INTERFACE
Showcase battery data on your phone! Connect two 12V Lithium batteries in parallel to double the Amp-hours, or in series to create a 24V system. The integrated DALY Battery Management System is easily accessible via a mobile app.
With the App, you can monitor and verify the battery's current state of charge, voltage, cycle status, and temperature, as well as individual cell voltages and their minimum and maximum voltages.
The BMS includes temperature sensors (for both prismatic cells and the BMS itself) to guard against over-charging, over-discharging, and short-circuiting, thereby extending the battery lifespan. Without a memory effect, this battery can be charged and used anytime under any conditions, eliminating the need for a full discharge before recharging.

batch products, we will repair and resend them to you, or discuss a recall solution based on the situation.
Q: Can I connect batteries in series and parallel?
A: Yes, you can. The maximum number that can be connected in parallel is 4. There are no limitations for series connections.
Q: Can I connect a 100 Ah battery to a 200 Ah battery?
A: Unfortunately, you cannot mix different types of batteries. All connected batteries must have the same capacity (Ah), voltage (V), and most crucially, must be the same battery type (AGM). For optimal performance and safety, it's best if they are from the same brand.
4.Q: What's the best way to place and store this battery?
A: This is a sealed battery, and we highly recommend placing it upright. It can be placed on its side only if absolutely necessary, but NEVER upside down. Store it in a dry, cool location (5°F~104°F / -15°C~40°C). Ensure the battery is fully charged before storing and recharge it every three months.
Q: Can I discharge the battery to 0% and then recharge it again?
A: To preserve the battery's cycle life, avoid discharging it below 50%. When not in use, charge it to 100% before storing and recharge it every three months.
Q: I plan to stay in my forest cabin during the winter holiday. Can this battery operate at freezing temperatures?
A: The discharge working temperature range is 5°F~122°F (-15°C~50°C), and the charge temperature range is 5°F~104°F (-15°C~40°C). Operating the battery outside these ranges will shorten its lifespan. Check the daily temperatures of your location before using this AGM battery under such conditions.
Q:
Would two 100Ah batteries be better or the same as one 200Ah battery?
A:
Regarding capacity, they are the same. However, two 100Ah batteries offer more resilience. If one 200Ah battery fails, you're left powerless until it's replaced. With two 100Ah batteries, you still have a functional battery if one fails.
Q:
I consume 17k watts of power daily. How many of these batteries do I need for my power bank?
A:
To calculate, divide 17kWh by 12V, equaling 1417Ah. For a reasonable service life, batteries should be discharged to a maximum of 50%, requiring 2834Ah at 12V. You would need 15 of the 200Ah batteries (or 29 100Ah batteries). Additionally, ensure you have about 20kWh (1700Ah @ 12V) of daily charging capacity to account for storage and discharge inefficiencies.
