ISDT BattGo BG-8S LCD Display Digital Battery Meter for LiPo/Life/Li-ion/NiMH/Nicd

Works great, must have in your RC toolbox. Very compact too. Dirt cheap for what it can do. Not sure how accurate it is, I guess we would need to compare it or use calibrated equipment to verify it but the batteries I use seem happy with it, they seem properly balanced, I double checked with another device and get the same per cell readings.

I like this meter and use it every time before I go flying to check the voltages of battery packs to match them for parallel charging, and while flying to check how much juice is left after coming down. Works very well for cells from 2S to 8S. 1S works in principle, but you will likely need an adapter to plug your battery into the balance port AND another 2S+ battery to supply power to the unit then. For 2+S packs usage is super simple, just plug the balancing lead into the device and you will get cell voltages displayed almost instantly, very convenient, no need to bother with the XT-60 connector in this case. It can also balance cells and act as an USB power source for e.g. charging your cell phone. I have rarely used the balancing feature, as I always balance charge before flying and a healthy LiPo pack shouldn't be unbalanced after discharging it to 3.8 - 3.75 V (per cell resting) or so anyway. The display is easy to read inside and outside and the user interface is good via three buttons. But again, for its main function of checking cell voltages you won't have to press any of those. I think it is expensive for what it is, but if I lost this one I would get a new one, it's that convenient.

Use with up to 8 cell lipos, gives voltage for each cell and total, plus percentage of power available. Also can balance all cells to lowest. Highly recommended item and seller.

In the field you really only need to get a general reading of your cells. Showing you all cells at once is the only option for me and this does that. As for accuracy it is good enough for the field, and to balance the cells in the pack I would say it does a great job. When checked with a Fluke meter the accuracy is at +/- 0.01 or better, but typically consistent across all the cells. Love the color screen which is easy to see in bright daylight. Also nice option to be able to charge USB devices such as the DJI Goggles battery. When balancing cells it is consistent across the cells and does not get hot, although this does only discharge cells down to the lowest one so it works fine for storage mode, but probably not designed for evening out at 4.195 - 4.20 volts before using. It'll just waste energy you could use for your application.

Jai essayé d'autre modele pour équilibrer la charge de mes batterie. Mais sa ne fonctionnait pas. Mais jai trouvé se produit et la wow. Sa fonctionne. Je recommande
