Question 1

Q1: How to claim warranty?

Accepted Answer

A: Once you receive your product, please register to claim your warranty on our
website.

Question 2

Q2: Why doesn't the B500K drain all its power?

Accepted Answer

A: The B500K retains a portion of its energy to prevent overdischarging, which
helps protect the battery's lifespan and ensures long-term performance.

Question 3

Q3: Can I leave the battery uncharged after fully discharging?

Accepted Answer

A: No, better to recharge it in time before its SoC drops to 1% to avoid
potential damage. Plus, place it somewhere with a temperature of at least 10°C
(50°F) for 12 hours before recharging.

Question 4

Q4:  Does the B500K support power bank mode?

Accepted Answer

A: No.

Question 5

Q5:  How many B500K batteries can l connect with AC300? Can l mix B500K/B300/B300S?

Accepted Answer

A: Up to 4 B500K batteries via the P090A cable.

Yes, you can mix use them.

Question 6

Q6:  How many B500K batteries can l connect with Apex 300? Can l mix B500K/B300K/B300/B300S?

Accepted Answer

A: Up to 6 B500K batteries. Use the CA90 cable for B500K stacks and the P090A
cable for more than 3 packs stacked separately.

Yes, you can mix use 6 packs at most.

Question 7

Q7: How many B500K batteries can l connect with AC500? Can l mix B500K/B300K/B300/B300S ?

Accepted Answer

A: Up to 6 B500K batteries via the P150D to P090A cable. Yes, you can mix use
six packs at most.

Question 8

Q8: How many B500K batteries can l connect with AC200L? Can l mix B500K/B300/B230/B210?

Accepted Answer

Up to 2 B500K batteries via the P090A cable, for 12,288 Wh capacity. You can
only mix with B300, B300K, and B500K.

Question 9

Q9: How many B500K batteries can l connect with AC200MAX? Can l mix B500K with other BLUETTI expansion batteries?

Accepted Answer

A:Up to 2 B500K batteries via the P090A cable.

Question 11

Q11: Can I use B500K alone as a UPS?

Accepted Answer

A: No.

Question 12

Q12: Can I use or charge B500K in sub-zero temperatures?

Accepted Answer

A: Technically, it can power devices below zero, but it can't be recharged.

Temperature ranges for B500K :

Charge: 0 to 40℃ (32 to 104℉);

Discharge: -20 to 40℃ (-4 to 104℉);

Storage: -20 to 40℃ (-4 to 104℉).

Question 13

Q13: How long can it run my device?

Accepted Answer

A: Runtime = Battery capacity × DoD × η ÷ (Device power +Self consumption) For
B500K, both DoD (Depth of Discharge) and η (inverter efficiency) are 90%, and
the self consumption is 3 W.

If you run a 100 W light bulb with it, the runtime will be: 5,120 Wh × 98% × 90%
÷ (100 W + 3 W) ≈ 43.8 hr

Note: For reference ONLY, actual results vary.

Question 14

Q14:  Is B500K waterproof?

Accepted Answer

A: No. Please do NOT place it in a humid environment for a long time.

Question 15

Q15:  Is it possible to replace the built-in battery?

Accepted Answer

A: No. If the battery pack is faulty or even dead, please contact BLUETTI
Customer Service.

Question 16

Q16: Any videos on connecting B500K with BLUETTI units (AC300, AC500, AC200MAX, AC200L, Apex 300, B300K)?

Accepted Answer

A: Please check out our BLUETTI Support YouTube channel for tutorials.

Question 17

Q17: How long can it run my device?

Accepted Answer

A: Running time = Battery capacity × DoD × η ÷ Device rated power DoD refers to
Depth of Discharge and η is local inverter efficiency. For B300K, both DoD and η
are 90%. If you run a 100W light bulb with it, the running time will be:

2,764.8Wh × 90% × 90% ÷ 100W ≈ 22.39hrs

Note: The above data is for reference ONLY.

Question 18

Q18: Can I use the B500K without a power station?

Accepted Answer

A: Yes, you can pair the B500K with BLUETTI ecosystem components to use it
independently. For instance, you can charge it using the SolarX 4K or the
Charger 2, and power your DC devices via the Hub D1.
