Just grabbed 2s-10s Polyquest or Hyperion Balance Board from Mr Positive | Rechargeable Batteries | Lipo Battery | Battery Charger at $15. It's a good series charger adapter having multiple balance connectors in row for seamless performance.
Worthwhile stuff indeed. I've Xtar WP6II Six Bay Li-Ion Battery Charger bought from Mr Positive | Rechargeable Batteries | Lipo Battery | Battery Charger, works well and still solid.
IMAX B6 Charger has got positive reviews about performance but never used. I bought icharger B+, found pretty on Lipos. Now, looking forward to buy solar powered charger, any recommendations?
