ISDTBattGo BG-8S Battery Meter，LCD Display Digital Battery Capacity Checker Battery Balancer Battery Tester for LiPo/Life/Li-ion/NiMH/Nicd

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.

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.

I LOVE this thing. Yes, a little pricier than the cheap ones, but love the quick glance fuel tank that shows how much battery you have left, if you have cells out of balance, you can auto balance them. Great screen too. I was surprised how good the quality was for the price honestly.

This meter is great for getting a quick reading of the battery or even balancing a small pack, but it is not precise within 10mv as even after calibration, the values will drift over time and even based on ambient temperature. It is perfectly fine for hobby packs but not if you need to check within 5-10mv of precision. The heat it generates from balancing actually throws off the readings more despite repeated calibration. The display however is very will Iit and easy to read.

We use 4 of these testers and they've all been very accurate, fast, and they are able to balance batteries *that are able to be balanced*. If your battery is shot or has a bad cell that can't go beyond X volts, this is no fault of the balancer. You have a bad battery.This little piece of hardware makes it quick and easy to check maximum cell variance in mV, overall charge percentage, and individual cell voltages as the first thing to display on the screen.We work with thousands of batteries, and these cell testers are great, and display the same information our expensive chargers do.The guy in the reviews with the Fluke doesn't know what he's doing, and it's easy to tell by his reported issues. You can buy an expensive name brand piece of equipment, but owning gucci gear won't make you an expert overnight, unfortunately. :)

Works great for my lev 60 battery bank

Bought this to monitor and balance the 100 Ah Sinopoly and 200Ah CALB LiFePO4 batteries. Will Prowse did an excellent job reviewing this on YouTube.1) Balances the cell by moving the power from higher voltage cell to lower voltage cells (not draining the current).2) Balancing function easily reached.3) Easy to read display. Turns blue when done balancing.4) Dependable, can leave on over night and weeks consumes very little power.5) User friendly, will boot up automatically and fast from unplugging and plugging.Strike: - Doesn't measure battery internal resistance.Bought one unit, worked so well that bought another. Will buy 3rd one soon.

Yep, its expensive, maybe even overkill at times but if you dont own one and you run more than 10+ packs in any given day, you need it. I wish I had more of them! Not only is it easy to read in the sunlight but the features are packed full. Did you know you can balance a battery all by itself by just plugging it into the ISDT BG-8S meter and that's it? Ive literally re-balanced my lipos in the field perfectly when noticed a cell dropped. One recommendation for the manufactuere: Remove the BattGo funtion or sell one without it for less $$. You will see sales go through the roof. No one really uses BattGo as far as I know. It just never caught on so sell one without it guys. Because everything else this thing does is amazing. Love it!
