If there was a higher amperage source available, would the system draw it? To answer this just take into consideration that a LiPo cell has a maximum charge capacity ( aprox 3,3 amp/h), so 1C=3,3 Amps/h. The cell could be discharged at a highier rate (more than 1C). But in order to prevent cell...

Hi Yako, I agree with you. There is little point in racking our brains trying to figure out whether or not the Mahle system has a 2 amp limiter on the main battery, whether or not it has a limiter on the extender, whether it does passive charging, whether or not it works in parallel with the...

Hello Chamzamzoo, Allow me to make an explanatory summary about the Mahle extender system and the options we have when building a DIY extender. These conclusions that I will summarize are the result of my careful analysis of the Mahle and Orbea specifications on their battery extender. As a...

Hi Yako, How small is the world.! Let me know if you have made any improvements to your extender, or if you have made new measurements. I have ordered some components and battery to build one. I think I am clear about the difference in the operation of the Orbea extender versus the one you have...

Hi Nealh, I would like to know if in all your experience with battery extenders you have built one specifically for Orbea Gain. If so, what has been the actual performance?

Hi Yak, I have read enough comments in this forum about DIY battery extender for Orbea Gain. I would like to know if you finally built your extender and if so what has been the behavior in reality.
