Pilot Paul Posted August 30, 2020 Share Posted August 30, 2020 (edited) Could anybody recommend a battery charger for my Bailey v4 battery please. It would need to have the correct lead to connect the battery as the terminals are covered with tape. Thanks Edited August 30, 2020 by Pilot Paul Quote Link to comment Share on other sites More sharing options...
cas_whitmore Posted August 31, 2020 Share Posted August 31, 2020 Hi , any 12v charger , with PB charge option , like model aircraft flyers use , you have to make up your charge lead though , edit , 240 mains power charger , some are 12 v and 240 input, Quote Link to comment Share on other sites More sharing options...
Pilot Paul Posted August 31, 2020 Author Share Posted August 31, 2020 Thanks Cas, I’ve got one somewhere from my old RC flying days . What’s PB charge option though? Also, any idea where I can get the connectors to make up the lead please? Quote Link to comment Share on other sites More sharing options...
Blackburn Mark Posted August 31, 2020 Share Posted August 31, 2020 I'm stumped on this connector, I have seen them before but cant identify.... you could cut the heat-shrink off to see if there is any ID markings on it or you could charge it fitted to the motor using the blue pug you showed showed us in another thread (after checking it is in the battery circuit) Assuming it is a sealed gel battery, a charger with a gel setting.... <14v seems to be a safe voltage for gel (up to 14.8v on wet lead batteries) but double check Quote Link to comment Share on other sites More sharing options...
Pilot Paul Posted August 31, 2020 Author Share Posted August 31, 2020 It’s all getting complicated I’m reluctant to cut the heat shrink as that’s a brand new battery from Bailey and cost a fortune! You think they would cover this stuff in the manual! Quote Link to comment Share on other sites More sharing options...
cas_whitmore Posted August 31, 2020 Share Posted August 31, 2020 If you’ve a charger with the lcd display , scroll through the battery options, life. Lipo , nimhs, Nicad , PB Quote Link to comment Share on other sites More sharing options...
alan_k Posted August 31, 2020 Share Posted August 31, 2020 PB = Lead, as in Lead acid battery. Quote Link to comment Share on other sites More sharing options...

The battery I have is knackered , I’ll take heat shrink off have a look , just so it’s clear , don’t use lead acid car battery charger , your battery is gel filled, not liquid electrolyte ( rain water) Quote Link to comment Share on other sites More sharing options...
Blackburn Mark Posted August 31, 2020 Share Posted August 31, 2020 (edited) 1 hour ago, Pilot Paul said: It’s all getting complicated If you make mistakes, your battery might have a shorter life than is necessary. Open wet lead acid batteries can typically take more abusive charge voltages/current because it is easy to top them up when they inevitably gas, sealed wet lead batteries cannot be topped up and Gel batteries can form permanent bubbles in the gel if charged with higher voltages/higher current. A SLOWER longer charge over a fast short charge is less harsh on lead acid batteries.... All three types are likely to read around 12.6v when fully charged (after they have sat idle for a few hours) If you are charging with a programmable RC charger..... both of mine allow me to set max current and voltage. IF I was in your position, I would limit the current to 2.0A 14.0v and make sure it didn't get too warm during charging... if it gets warmer than I am comfortable with, I would drop the current for a slower longer charge (I have the IMax B6 charger and Turnigy Accucell 6 // both very similar chargers) BUT, that is what I would do... Others might have better ideas Edited August 31, 2020 by Blackburn Mark Spelling :) Quote Link to comment Share on other sites More sharing options...
cas_whitmore Posted September 1, 2020 Share Posted September 1, 2020 The plug has Anderson power on it , ? 1 Quote Link to comment Share on other sites More sharing options...

Anderson power poles (like Lego ) Get measuring and search on ebay for "Anderson Power Poles".... pretty sure you will crack it from here.

cas_whitmore Posted September 1, 2020 Share Posted September 1, 2020 Thought It looked modular , didn’t won’t to force it apart though Quote Link to comment Share on other sites More sharing options...

Look for the holes in the image above, they take a small pin to stop the sliding apart lengthwise Quote Link to comment Share on other sites More sharing options...
cas_whitmore Posted September 1, 2020 Share Posted September 1, 2020 (edited) Holes there, no pin though might have a touch of cyno on them Edited September 1, 2020 by cas_whitmore Photo Quote Link to comment Share on other sites More sharing options...
