    Hi Roy
    Thanks for your in depth response, I have 3 x Planet T5's (2.4 Ghz) although usually only 2 are in use at the same time.
    The chargers I am currently using are Tronics as sold at Lidl and charge quite fast, however I believe they stop charging when a certain temperature is reached rather than voltage.
    As the charging cells get very warm in the process I use a fan to dissipate the heat and this lengthens the time taken to charge, which is why I am suspecting temp prioritises voltage.

    Hi Bikerjohn, I know that the high capacity AA cells look a good idea, there are some buts however. If you are using old 40 Mhtz or even 27 (like wot I duz) you will find that the new hi cap cells are a little fatter than the 600 and 800 mAh cells we used to use.

    You may not be able to get the back cover on the Tx.

    Also consider how long you wish to run the radio for. I am happy with a long afternoon say 3-4 hours. This means that you may be overlooking cheaper 2000mAh cells that will do the job just as well.

    I have some old 40 MHtz Tx's and have found another solution. I favour the 3 channel Hitec 40Mhtz FM Tx's as they are 2 proportional channels and a 3rd. ch with a set position that I use for sail trimming.

    Component Shop made me a couple of 10 cell 12 volt AAA batttery packs. These are 950 mAh capacity and last 4.5 hours. I asked for a normal servo end connection and soldered a female end on a wire into the back of the Tx. It can be charged en situ.

    I do not need to remove any cell contacts as the pack fits in nicely and best of all it is cheaper!

    I use an intelligent charger that can handle 10 cells or 12 volts, choose carefully as not all of them can, I think it cost ยฃ13.

    I am not conversant with 2.4 Ghtz but I understand some run on just 4 cells.

    Sorry to muddy the water.
    Roy

    Hi John,
    The B6AC is very nice, but has all sorts of bells and whistles you don't need for charging single cell NiMh TX batteries. Ultimately the choice is yours (and your budget's!) Happy investigating.

    Many thanks to all that helpfully replied, was considering the Imax B6AC and was surprised it only received one recommendation, looks like I need to investigate further.

    Depending on whether they are single cells or in a pack there are several types available. Try looking at
    https://www.componentshop.co.uk/chargers/standard.html
    The site also lists chargers for made up packs.
    I have used many types over the years and all work well and are suitable for your purpose.

    I use 2800 mAh EBL or 3100 mAh Xtech Ni-MH batteries. I use these in two-way radios as well as RC radios. The high mAh rating on these batteries give me an outstanding run/use time. I bought both brands with a charger from the manufacturer. I'd easily recommend either of them. I bought Xtech off eBay, and EBL off Amazon.

    So far my collection resembles "The Island of Misfit Toys". I've picked up several boats that are old builds and have been neglected. I'm giving them the TLC they need, hoping to bring them back to their former glory. Once I get enough practice/ experience I intend to take on a full build.
