This is a mod to essentially refurbish your stock Solo battery with new cells. The cells used are the Tattu 4S 5200mAh 35C.

For a fully ready to fly Solo smart battery choose the default options, then send in your Solo battery or BMS to:
Jon Brotherton
4142 Cedar Dr.
Grapevine, TX 76051

Please note that this battery must be secured with a 400mm velcro strap. It does not snap into the Solo's battery latches. It performs in all other ways exactly like an original Solo battery.

For semi DIY, send in your old Solo battery (or remove the BMS and send it) and we will extract the BMS and install the BMS into an optional enclosure with all soldered on standard connectors (4S balance and XT-60) for a standard LiPo battery to connect. You connect the battery and calibrate it yourself.

The battery mod and strap weighs 490g.

Send your Solo battery to:
Jon Brotherton
4142 Cedar Dr.
Grapevine, TX 76051
