Onbo Batteries BATTERIES BY Onbo-Power UK Distributor Me and my flying friends which included John Greenfield of the Ghost Squadron have tried lot of Lipo batteries from many companies, but found that most of these batteries we have found out afterwards that most are grade C quality cells, and when it comes to replacing the batteries after a couple of charges it has taken me 3 months of many e-mails one after the other In my own opinion this is why they can be cheaper then some, so I looked and looked through the internet and found a company called ONBO POWER I have had some very interesting chats with the company, and what I liked about this company was they had time to talk and listen to your requirements and to see how they could supply the correct battery and connectors that you require, with no extra charge. There prices were slightly more expensive than other companies that sell batteries that was C grade that would puff up after a few flights and in some cases before they were even used, some companies even say there batteries will puff up, I couldn't believe this when I read this in the battery description. Onbo batteries are a lot cheaper than the uk shops named batteries. but what swung it for me was the extra power , like a 4000mah battery, ONBO ones are 4200mah but lighter then the lower powered one and smaller this means longer flying time , this means the extra power will not be lost in weight being carried by the motor. So you really do get extra power to use as performance or longer flying time. There C rating has a wide range frome 20C right upto 95C on certain batteries, They also have some very good Lif'e battery packs and is one of the biggest selling batteries that has been sold in the uk mainly used as RX packs, 2 off packs of 3800 25C 2 cell packs are only slightly heavier than 1 pack of 6V 5 cell Nihms, and not like Nihms they dont drop in voltage when under load. We found this out with our glider flying with telementry pluged in we would hear the voltage drop when servo's on the gliders would be used, so once changed over to Lif'e batteries there are no drops in voltage for most of the day on the same battery packs. Now a large amount of the glider ferternity a round the uk now use Onbo batteries and Powered user's are now using these batteries.

I have found the best way is to buy in a group order this then cuts the p+p and danger tax down by splitting the cost, when being shipped out of China via UPS delivery,and this keeps the price of the batteries down.
