Be aware batteries wires come out middle top corner making them go directly towards pinion and spur. Mount battery a different way you say? You can if you force wires down against side guards possibly causing damage to wires, battery, and potential fire. Needs re-design

Awesome and great battery for my losi mini T 2.0 perfect fit no mods needed, great power and battery life 10/10

Bradley DanielVerified owneron Gens Ace 2S LiPo Battery 60C (7.4V/850mAh)

Great battery for the Mini B and Mini T, fits perfectly without any issues. If you're running Brushless may want a connector adaptor or change the connector type if you don't like making it fit without one.

Connector did not fit my Mini-B Brushless. Great battery otherwise, just had to solder on a new connector.

What reviewers say

Reviewers generally praise this 2S 850mAh LiPo for fitting Losi Mini-B and Mini-T chassis well and for good runtime and power for the price. Several note the fit is tight, with one saying it leaves no room to spare. Connector compatibility is the main point of disagreement: one reviewer found the EC2 connector did not fit a brushless Mini-B and had to solder on a new connector, and another suggested a connector adaptor for brushless use. One reviewer reported that the wires exit at the top middle of the battery, routing them toward the pinion and spur, and said that forcing a different mounting risks wire damage and fire, calling for a redesign. Reviews are few.

  • + Fits Losi Mini-B and Mini-T well
  • + Good runtime and power for the price
  • + Added capacity over stock packs
  • − Connector may not fit brushless Mini-B without modification
  • − Tight fit with no clearance
  • − Wires exit toward pinion and spur, risking damage
