Tenergy 4.8V 2000mAh Capacity NiMH Battery Pack with Hitec Connectors, Futaba, Square Rechargeable Battery for RC Receivers, Airplanes, and More

The OEM batteries for HP RAID controllers are far too expensive, so we purchased this generic pack. The server/controller provides charging for the cache batteries and that works just as well for these. While the form factor is different there's plenty of room to tuck this pack into the server. It has been working well for a couple of months now and we expect it to continue.

I formed charged this battery and then completed a discharge. The first cycle showed 1980 mAh. The second cycle exceeded the 2000mAh battery capacity. Unlike other batteries I have purchased, this battery actually provides the advertised capacity. I will purchase more.

I've been using this one pack for almost a year. It's held up very well through many charge/discharge cycles. No problems with it.

Used in an RC device, works great.

This battery holding up good and holds a good charge

Although this battery is for RC cars and such, I actually bought it to replace the battery in my cordless vacuum, which required the same voltage. After a couple of easy splices, it worked perfectly and with greater staying power. The battery from the company was 3x the cost of this one, so it was a great cost-saving upgrade.

Works great in my rc sailplane.

I fly a lot of 80’s era gliders and these packs fit the traditional (4) AA size battery that the designs typically accommodate. LiFe’es are lighter and more trouble free but for a traditional battery, this product has not let me down. Wiring is solid and lots of mAh for my needs.
