A: Yes, you can. The maximum number that can be connected in parallel is 4. There are no limitations in series.
Q: Can I connect a 100 Ah battery to a 200 Ah battery?
A: No, you cannot do that. To ensure optimal performance and safety, all batteries connected must be of the same capacity (Ah), the same voltage (V), and most crucially, the same type (AGM). Ideally, they should also be from the same brand for compatibility.
4.Q: What's the best way to place and store this battery?
A: This is a sealed battery, and we recommend placing it upright for optimal performance. If special circumstances require, the battery can be placed on its side but never upside down. Store it in a dry, cool area with temperatures ranging from 5°F to 104°F (-15°C to 40°C). Make sure the battery is fully charged before storing and recharge it every three months for maintenance.
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%. For periods of non-use, charge it to 100% before storing and recharge it again after three months.
Q: I will be staying at my forest cabin during the winter holidays. Can this battery be used in freezing temperatures?
A: The discharge operating temperature range for this battery is 5°F to 122°F (-15°C to 50°C), and the charging temperature range is 5°F to 104°F (-15°C to 40°C). Using the battery outside these temperature ranges may shorten its lifespan. We highly recommend checking the specific daily temperatures of your location before using the battery.
Q:
Would 2 100Ah batteries be better or the same as one 200Ah?
A:
In terms of capacity, 2 100Ah batteries are equivalent to one 200Ah battery. However, 2 100Ah batteries offer a significant advantage: if one fails, you still have the other to rely on, unlike with a single 200Ah battery, which would leave you without power until it is replaced.
Q:
I am consuming 17k watt power per day. How many of these batteries will I need for my power bank?
A:
To support a daily consumption of 17 kWh, you need to divide this by the battery's voltage (12V), resulting in 1417 amp hours. Considering batteries should not be discharged below 50% to ensure longevity, you would need 2834 amp hours of rated capacity at 12 volts. This equates to 15 of the 200Ah batteries, or alternatively, 29 100Ah batteries. Additionally, ensure your charging system can provide about 20 kWh (1700Ah @ 12 volts) per day to account for storage and discharge inefficiencies.
