Two small rectangular lithium-polymer batteries side by side

Common Sense RC

Common Sense RC Lectron Pro 3.7V 175mAh 45C Li-Po Battery 2-Pack drone accessory

SKU CH-A5GP-TQ6BF

Two 3.7V 175mAh 45C Li-Po cells extend flight time for Blade 70S and similar micro RC models

  • Longer sessions with 175mAh capacity
  • Responsive maneuvers from 45C discharge rate
  • Agile flight preserved by 0.18 oz weight
  • Perfect fit in Blade 70S at 1.61 x 0.47 x 0.24 in
  • Upgrade over standard 150mAh packs

Compatible micro-drone power

The Lectron Pro 2-pack supplies 3.7V 175mAh single-cell lithium-polymer batteries built for the Blade 70S and similar micro RC aircraft. Each cell delivers a 45C continuous discharge rate for responsive throttle control. The pair replaces standard 150mAh packs to extend session length. Hobbyists who need quick swaps between flights gain a ready spare.

Thermal and power behaviour

At 5 g per cell the mass stays low enough to preserve the airframe’s agility during high-rate manoeuvres. The 45C rating supports sustained current draw without voltage sag that would shorten flights. No active cooling is required in normal micro-drone use. Pilots who push continuous full-throttle runs beyond the cell’s thermal limit will see performance drop.

Included hardware impact

Two pre-wired cells arrive ready to install; no soldering or connector changes are needed for the Blade 70S. The 41 x 12 x 6 mm footprint matches the stock battery bay exactly. Builders whose frames demand a different connector or larger capacity must source adapters or higher-capacity packs separately.

Questions about this item

How do I install the Lectron Pro 3.7V 175mAh battery in my Blade 70S and what step causes the most issues?

Slide the battery into the compartment until the connector clicks into the JST-PH port; the step most pilots miss is fully seating the plug so the latch engages, otherwise the drone loses power mid-flight.

What maintenance or replacement will these 45C Li-Po packs need over time?

Inspect each 5 g cell for puffing or voltage imbalance after every few flights; retire a pack once it no longer holds a full 175 mAh charge or shows physical swelling.

Which limit appears first during extended high-throttle runs with the 45C discharge rating?

The 175 mAh capacity depletes in roughly three to four minutes of aggressive flying, so flight time ends before the 45C thermal limit is reached.
