Brand Name: | Heltecbms |
Certification: | FCC |
Origin: | Mainland China |
Warranty: | One year |
MOQ: | 1 pc |
Battery Type: | LifePo4/Lipo/LTO |
Balance type: | Capacitive Energy Transfer / Active Balancing |
1.5A active balancer *1set.
2.Antistatic bag, antistatic sponge and corrugated case.
3.With acrylic protective case(Optional).
The bigger the differential voltage, the bigger the equalization current; and the more balanced the battery, the smaller the working current. This active balancer can reach the maximum equalizing current of 5.5A and the balance voltage accuracy is within 5mV. Meanwhile, it will only release less than 0.1mA current under sleep mode.
With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 3.0V for NCM/LFP battery, and 1.8V for LTO battery. The standby power consumption is less than 0.1mA.

More versions:
1. Version for using on LTO battery by default (Welding LTO pad of Balancer 4-6S/6-8S/12-16S/9-14S/17-21S)
2. 5.5A balancer for LFP battery , stop when first cell voltage is 3.3V and start working when voltage is 3.465v
3. Add PH2.0 connector at RUN pad ,balancer is not working by default. Ship the cable together
* We keep upgrading products to meet requirements of our clients, please contact our sales person for more accurate details.
Take the standard 3-4S 5A Balancer (0855A) as example to demonstrate the updated versions of our 5A active balancer. Most of the balancers can be customized. Please contact our sales person for your own application.
SKU |
Definition |
0885A |
Standard version. |
0855C |
For LTO battery only. (not for NCM/LFP) |
0855D |
Stop balancing when cell 1 (the first cell of the first string) is 3.3V; and when it reaches 3.456V, re-start balancing. |
0855PH2 |
PH2.0 connector instead of RUN point, balancer not in work by default. Wires can be connected to a switch or any BMS, so you can control the on and off of this balancer. |
For example:
You have 16S LFP/NCM cells, and you want the balancer to stop balancing when cell 1 (the first cell of the first string) is 3.3V; and when it reaches 3.456V, re-start balancing. You can choose our 0999A16D balancer.
It has the same appearance as standard version but changed in chips design.
You have 6S LTO cells, you can choose our 1004C balancer. It’s specially designed for 6S LTO battery.
You have 4S LFP cells and you want to be able to control the on and off of the balancer, you can choose our 0855PH2 balancer. Connect the other end of the additional red wire to a switch or soldered to your BMS, you can turn the balancer on and off without keeping it working all the time.
TFT-LCD Display (with voltage collection function)
It is connected directly to the battery and can be used in parallel with any balancer or protection board. It displays the voltage of each string and the total voltage. Regarding accuracy, the typical accuracy is ±5mV at room temperature around 25°C, and the accuracy is ±8mV in the wide temperature range of -20~60°C. The direction of voltage deviation cannot be guaranteed to be consistent.
