To improve the energy density of lead acid batteries, Yaheng started developing the Bi-polar battery in 2021. With complete production chain for lead acid battery business, Yaheng has great advantage in developing new batteries. And Yaheng succeed in developing the bi-polar batteries. 12V12AH(BP12-12) Bi-polar battery is brought to market in March, 2023. 12V12AH(BP12-12) Bi-polar battery, size L 151*W 98* H 95/98 mm, weight 3.8 KGS, capacity 12AH@ 2HR, 16AH@20HR.
Capacity Test Report:
| ITEM | Model | Dimension（mm） | Weight | OCV， | CCA | Discharge current 6A | Capcity |
| 1 | BP12-12(12V12Ah) | 151*98*98(101) | 3.8KG | 13.3V | 135A | 2:3:12 | 12.3Ah/2HR |
12V12AH Bi-polar battery applications:
UPS
Security System/CCTV,
backup power system,
Electric Scooters, Electric Wheelchair, Electric Bicycle.
12V12AH(BP12-12) Bi-polar battery characteristics:
Continuous discharge at high rate workable
20% more energy density.
Consistency in Capacity, OCV, Inner resistance improved
Charge acceptance can get to 97%, save more than 20% charge cost
High rate charge and discharge rate, no need BMS
25% more cycles than traditional EV battery
Produced according to IEC60896-2-1
Vibration and drop test OK, U.N. 3.3 Special Provisions 238 approved
Pass the California Proposition 65
Yaheng’s advantage in developing new batteries:
Complete production chain for lead acid batteries: materials, plates, machinery and automatic production lines
Cooperate with famous R&D organizations.
Experienced engineers team
More than 45 years of technical reserve
Chemical formulation for different applications reserved.
Unique configuration makes the discharge high efficiently, can be discharge at high rate frequently. 10C Performance is very good.
Good consistency improve the battery banks performance
The inner resistance decreased too. The Bi-Polar batteries have very good charge acceptance. The normal charging time can be shortened by 20%.
12V12AH(BP12-12) Bi-polar battery has very good cycle life:
Discharge at 100% DOD at the first 200 cycles, the capacity is almost same
100% DOD to 70% remained capacity near 400 cycles.
With advantages such as higher density, high charge acceptance, longer cycle life and low cost, the 12V12AH(BP12-12) Bi-polar battery is competitive in applications of UPS and electric vehicles.
