Wellpower Lipo batteries with a sensational price-performance ratio! SE Series = high-quality workmanship, outstanding performance data, and the best price-performance ratio! Depending on the type, they can handle up to 100C (peak current) and charge currents of up to eight times the nominal capacity, making our Wellpower Lipos the first choice for ambitious model builders. Balancer connector system XH. Version V2 comes standard with a specially made Liposafe tailored to the battery size (from 1000mAh) for maximum safety during transport and storage. The battery along with the Liposafe can even be installed directly in the model (be mindful of temperature development!). For cost-conscious model builders, we specifically offer the ECO Series, which has slightly lower nominal load capacity and does not include a Liposafe, but maintains the known quality features at an unbeatable price. Splitpacks have two balancer and four main current connections. The ULTIMA version features true 35C or 60C continuous load and peaks between 70C and 90C (1 sec.) or 120C (max. 0.5 sec.) for uncompromising applications such as competitions. The CHECK version comes with a built-in LED voltage indicator for a quick test of the battery's charge status.
Discharge currents SE/V2: Values in parentheses apply only for short-term loads (max. 5 seconds). Charge currents: CHx values indicate the maximum allowable charge current. For CH2, for example, this is twice the nominal capacity (so for a 2.0Ah battery, max. 4A), CH6 is six times the value, and so on.
Tip:
- The maximum continuous discharge current is only recommended with active temperature monitoring!
- Preheating cold batteries increases performance and lifespan.
- Never allow batteries to exceed 60°C.
- Recommended storage voltage is 3.70… 3.80 V / cell.
- Protect against short circuits, mechanical damage, overheating, deep discharge, and overcharging.
- Only charge on a fireproof surface with a suitable LiPo charger.
- Do not reuse damaged cells!
