Gens Ace Lipo Battery Charger IMARS D300 G-Tech Series Smart Dual Lipo Charger 16A AC 300W DC 700W Lipo Charge（White）

Fast charger. i dont have any super large batteries 5200mah largest, for now. My old charger could only charge one at a time and not near as fast as this. The old charger was always getting hot to the touch, this charger does get warm but it has fans that kick on as needed to cool it off. the fans can be loud, but they are powerful so its a necessary evil.Please be careful and charge your batteries responsibly and not on 16amps for everything. yes they will charge faster but its potentially dangerous and not good for the batteries. But the option for both sides to charge at 16amps is huge! sadly the discharge is not near as fast but we should have more fun ways to discharge batteries anyway.

Great charger for a great price point! The storage function is great for RC enthusiast utilizing LiPo or LiHV batteries. The charger is small and compact which makes packing up easy!

Great charger. The size of it makes it easy to travel and store.

I want to preface my review by saying I had done a ton of research into chargers and had watched a countless amount of Youtube videos looking for a charger that would work for my needs. I needed a charger that could charge Lipo and Li-ion battery packs for FPV quads as I had recently gotten into the hobby. Needless to say, all the "Best options" that were pushed heavily by a lot of the major FPV channels were definitely seeming like they'd fit the bill, until I saw what the "bill" would be. $250-$300 for a charger seemed to be the norm. and they were all 400watt chargers. I couldn't really find a decent 400watt charger for under $250... so I started looking at some 200watt chargers and they just didn't seem like they'd do what I wanted in the long run. That's when I stumbled on this charger browsing amazon. It was the perfect middle of the road charger. 300Watt and at less than $150... I made up my mind and pulled the trigger. Once I got this thing... I immediately realized how much of a value it was. I charge at 1C with mainly 6S lipos but also 6S li-ion packs that I've built, but this can satisfy pretty much any of your charging needs. It's fast, it's not terribly loud, (the fan is only on at max load) and it was super intuitive in the way that it functions. I'm a big fan of the menu navigation, despite there being so few buttons. It also remembers your last used setting after a power off, so I can have one side configured for my lipos, and the other for my li-ion packs and charge both at the same time without having to get back into the config menu each time unless I'm changing the charging current for different mah packs. I've been using it for a while now and I have been so impressed I went out of my way to write my review. This is a great charger.

Awesome charger, charges fast, fan is very quiet, different charging modes.If you have gens Ace battery with g connection, this will work even better!

Works very well.

I've put at least 100 charges thru this thing so far from 2S lipos from 750mah to 5200mah, 3-7s nimh, even 6s nicd, and it's been great. I'll just get to the point and talk about some downsides I've seen that aren't deal breakers for me, but could be improved upon.Fan noise, it's fairly loud. I can say for certain if you charge two 2s lipos at 10.4A it'll stay on the entire time. WHHRRROne XT60 for power input OR discharge. while I haven't used an external PSU, being limited to ~15W discharge per channel could limit you if you're trying to charge 350W per channel.When discharging a 2s Lipo I can get ~1.7A of discharge, yet my 6s nimh/nicd batteries can only discharge 0.6-0.8A. not sure if this is a hardware or software limitation, but it's worth a note.Below are software things that could, theoretically, be fixed or added with a firmware update.Nicd mode, they still exist. I don't blame them for leaving this one out, would be nice to have.when using a g-tech battery the estimated time to completion gets stuck for me, every time on both channels. mildly annoying.Beep sounds awful on anything but high volume in my opinion.A volume control for both button inputs and charge completions would be a great addition.

This charger works great. It's compact size is great for taking to the field. With 150 watts per channel when AC power is used and it's 350 watts per channel when using it on DC makes it quicker charger than most anything it's size especially for the price. The user interface is easy to learn and use and it has most all the charging/discharging options you might use. In the Charge mode it Charges & Balances at the same time even though it has a separate Balance for those who want to fine tune their batteries. I had a Venom 4 channel charger and it worked well but was limited to 100 watts per channel and would only discharge at 0.5 amp. This charger will discharge from 0.1 to 3 amp. This charger handles these Supported Battery Chemistries: LiPo/Li-ion/LIHV/LiFe 1~6S; NiMH/Cd 1~16S. A great buy for the price given the size and power.
