As a note - The latest copies of the instructions and warnings included with all Thunder Power LiPo batteries specifically state: DO NOT USE the Super Brain 969 charger.

I used to run the service center for Thunder Power (Ive since moved to marketing and promotions). When the 969 first came out, we received dozens of packs ruined due to overcharge by the falsely advertised ability of this charger to safely charge LiPo packs. After further evaluation, it was found that the Super Brain does not feature a "constant current / constant voltage" method for charging LiPos. It expects the user to "guess" how much capacity is left in their packs, then charge what they "think" the pack needs. If at any time the person was to guess wrong, the pack would typically swell from overcharge. Worse yet however, the pack could vent and cause fires.

Capacity charging is one of the most unsafe ways to charge a LiPo pack. Regardless of whether you monitor the charge like a hawk or not, the damage is already being done. I would suggest anyone using the 969 to charge their LiPos, even if it has appeared to work fine, purchases a proper LiPo capable charger.

The safety of yourself and your family is at risk, and its simply not worth it.
